Concept Details
1.Incredibly Low Price & Made in Yokohama!
FLEX Z inherits all the features and quality of STREET FLEX but the adoption of new platform allows its price to be set at amazingly low range ($800 to $1,050). FLEX Z, of course, maintains the long-favored "Made in Yokohama" quality. Ride height adjustable shock absorber, fully loaded with TEIN's comprehensive technology, is now more affordable prices than ever.Sealed Structure

New Approach to Achieve Amazingly Low Prices
After careful consideration, we came to the conclusion that we need to establish new manufacturing systems and to develop a new product platform, in order to achieve low prices the customers demand. Until now, all TEIN dampers can be disassembled for overhaul; Now, we introduce our new "Sealed Structure" for the FLEX Z. Below is a brief description of this new production process for our FLEX Z at TEIN HQ Factory in Yokohama, Japan.
Top end of shell pipe is drawn, oil & gas are injected then the opening is completely sealed by crimping process. This "Sealed Structure" process also reduces the production time, compared to the production of existing disassembable dampers.
In addition, pursuit of efficient production system, such as use of seam welding, allows us to drastically reduce the production cost.
2.Twin-Tube System for Comfortable Ride on Streets!
Considering the use of larger tires/wheels and the lowered ride height, FLEX Z uses twin-tube system, in pursuit of ride comfort on streets.

In order to maintain the ride quality on streets with rough spots here and there, a shock absorber has to have sufficient stroke, be low-frictional and move smoothly.
As an oil chamber and a gas chamber are not arranged serially in a twin-tube system, it is easy to secure enough stroke. Also, low gas pressure keeps friction low.

Its smooth stroke movement makes it possible to follow rough and bumpy road surfaces quite well, offering supple ride at low speed and stable ride at high speed.
Twin-Tube Clear Model
3.Full-Length System for Ride Height Adjustment w/ Minimal Change in Ride!
Full-length ride height adjustment system, used for FLEX Z, enables adjustment of ride height by adjusting the case length, without changing the damper stroke length and/or spring pre-load. This has the advantage that the change in ride quality is kept minimal when the height is adjusted.
This system not only makes it possible to maintain good balance between the low-down appearance and ride comfort, but also provides more setting choices for sport driving as well.

4.Damping Force Adjustable to Change Ride to Desired Settings!
FLEX Z has ever-popular 16-level damping force adjustment (comp./rebound together) feature with the use of needle valve. By turning the adjustment knob, damping force (stiffness) is adjusted linearly step by step, to change the ride and handling of the car to suit driver's needs/preferences. 
Use of well-reputed "ADVANCE Needle" at the needle valve for oil flow control secures sufficient damping force adjustable range. 
Whether it's for the handling characteristics of sport driving or for the ride quality according to numbers of passengers, finding the most desirable setting is easier than ever.

5.Compatible with EDFC Series to enable In-Car Damping Force Adjustment!
With EDFC (Electronic Damping Force Controller) series installed, damping force can be controlled from the cockpit with ease. Stepping motors attached in place of adjustment knobs control the damping force quickly and accurately. 
Use of EDFC turns 16-level adjustment into finer 32-level or 64-level adjustment mode (64-level only available with EDFC ACTIVE / EDFC ACTIVE PRO), to provide the optimum performance by fully utilizing the damping force adjustable range drastically widened by the use of "ADVANCE Needle". 

With EDFC ACTIVE / EDFC ACTIVE PRO, damping force can be controlled automatically according to changes in G-force and/or vehicle speed, to offer very smooth and slick ride like never before. (Some models are NOT compatible with EDFC series.)

7. Highly Durable & Reliable!
After many years of research and study, TEIN has developed optimally-shaped dust boot made of most suitable material. Elastic & highly-durable dust boot effectively prevents damages to the piston rod and foreign substances from getting inside the shock absorber. 
(Some vehicle models use OE dust boots.)

Final assembly of shock absorbers is done in the clean room, which is almost equivalent to operating room. Room pressure is kept under control to shut out dust & dirt and all workers entering the room must take air shower, to make sure all the assembly work is done in completely clean air, in order to maintain higher level of accuracy and reliability.

8. Thoroughgoing Rust-Proofing!
Upper mounts and lower brackets are coated with rich TEIN green powder paint. This powder paint has high coating film strength, is highly durable yet is low-pollution due to non-use of harmful solvent. After the shot blasting pre-treatment, the patented "2-layer/1-bake" treatment using anti-rust powder paint is applied for superior durability and high corrosion resistance. (Patent No. 4347712)
Powder Paint

On shell case, TEIN's self-developed one-of-a-kind "ZT Coating" is applied, for tougher protection against chipping, often caused by bounced pebbles, and rust. With zero claim rate, against adhesion, out of 500,000dampers sold, we are confident that people living in snowfall area or near seashores would even be very satisfied.

9.Highly Durable & Reliable!
For strut suspensions, sufficiently-thick ribbed plate is used for knuckle bracket to maintain high rigidity. Flange shape edge of the bracket provides larger contact area with the bracket lock, which is fastened with the conical washer inserted in between, to effectively prevent loosening of the bracket lock most commonly occurs on front strut suspensions.
Brackets for brake hoses and ABS sensor harnesses etc are exclusively designed for each vehicle model for hassle-free installation.

10.Smooth Ride Height Adjustment & One-of-A-Kind Adjusting Wrench!
FLEX Z has adopted the new wrought aluminum spring seats and low-friction hard-resin thrust washers. These effectively reduces the friction with springs, caused during ride height adjustment, and makes it easier to adjust the ride height with pre-load on the springs.
Shell cases are treated with "ZT Coating", a superlow-friction fluorine resin coating, which is tightly baked onto the surface in-house. This special coating provides superior protection against rust and high lubricity, for keeping a smooth adjustment for a long period. 

FLEX Z kit includes one-of-a-kind user-friendly ride height adjusting wrench. It has a 12.7mm (1/2in) sq. hole for attaching spinner handle and/or torque wrench for tightening at high torque.

11.No-Sag Springs!
Included springs are made of high-tensile steel SAE9254 (tensile strength 200kgf/mm2 or over) and cold formed for excellent resistance to sagging and for superior quality stability.
Surface is powder coated for superb protection against chipping & peeling, for high durability and for superior anti-corrosion performance.
High-quality spring can be used under various conditions without any worry.
The most suitable shape of spring (straight or barrel-shaped) is determined for each vehicle model, to provide wide ride height adjustable range and to secure sufficient stroke without compromising ride comfort.

12.High-Spec Damper Oil
Specially-formulated high-spec oil exhibits stable viscosity characteristics at any temperature; from low to high, to allow shock absorbers to stroke smoothly and to generate damping force stably under various conditions. The oil has superior anti-foaming characteristics hence the bubble cavitation and/or thermal degradation hardly occurs, making it even suitable for tough sport driving. The oil also does not deteriorate much with age, making it possible to maintain and deliver superior performance for the long term.High-Spec Damper Oil
13.Replacement Service to Bring Used Shock Absorbers Back to Life!
TEIN makes NO compromise on after-sales service of FLEX Z. Replacement Service is available for FLEX Z, in the place of overhaul/revalving service, as its "Sealed Structure" components cannot be disassembled.
How "Replacement Service" Works
  • NO need to return the original shock absorber
As shown above, Replacement Service allows the customer to purchase and replace the shock absorber body, excluding outer parts (upper mount, lower bracket, spring etc.).
For Overhaul/Revalving service, because the shock absorber has to be detached from the vehicle, sent back to TEIN and then returned to the owner once the job is done, there are some disadvantages;
  • Need to prepare loaner (substitute) shock absorber while waiting for overhaul job,
  • Require to do removal/installation twice, and/or
  • Can not use the vehicle left on the lift while waiting for overhaul job.
Replacement Service is time-efficient as the customer can purchase a replacement shock absorber in advance and replace with the old one whenever ready.
Replacement Shock Absorber is Customizable!
You might think that the major advantage of overhaul/revalving service, damping force and/or stroke change, is not available for FLEX Z due to its "Sealed Structure".
Well, TEIN made it possible.
Upon request, we can make the replacement shock absorber to the desired damping force specifications and/or stroke length, to the extent possible. Because the original shock absorber does not have to be returned, you can purchase and stock several replacement shock absorbers in different specifications for various purposes, not just as replacements for worn-out ones.

Such enriched after-sales service is only made available by "Made in Yokohama" quality.

98-05 Lexus GS-300 TSP Racing G Series Street Coilovers (COSGS-LE-05)

Product Description

TSP Racing G Series Coilover kits are built for road and track use, TSP's Coilovers are fully height-adjustable, allowing you to keep the ride height the same as factory, or up to 50mm/2in lower. Damping of the piston valves are matched to each spring rate. The springs are preloaded from the factory, so you don't have to configure that before driving. Just set your ride height and damping preference with the 24 click linear adjustments.

The engineers in our factory invest time and money into research and development to ensure the highest quality, best performance kits on the market. TSP Racing Coilovers are not 'one size fits all' with adapters. Each kit is designed specifically for the vehicle, and all kits are tested and developed to ensure maximum performance.

Instruction Manuals

Got your new coilovers and need to know how to properly adjust them?

Instructions


Aluminum alloy upper mounts, surface anodized treatment, very strong, heat-resistant, wear-resistant, corrosion-resistant aluminum oxide layer. TSP Racing rubber top plates are utilized frequently on our kits. If the front of the vehicle utilizes a camber plate, the rear will use a rubber top plate, although pillowball tops are frequently available for dedicated track vehicles. For all kits in which a camber plate cannot be utilized (A-arm suspensions) the top plates will be rubber front and rear. The main design feature of the rubber top plate is that it dampens NVH from reaching the cabin as much as possible enabling an OEM-like quiet ride. All rubber top plates have a durometer rating of 75A in order to achieve the best balance between performance and comfort.

Pillow Ball Top Hats

The pillowball top plate is used as an upgrade in the rear of a vehicle in lieu of the rubber top plate. Rubber is used as standard to limit NVH from making its way into the cabin although this upgrade is available on various chassis at the customer’s request. Please contact us directly to see what options are available for your specific platform. The pillowball top plate is a good upgrade for customers seeking a more track oriented, rigid setup where NVH is not much of a factor.

Camber Adjustable Top Hats

Camber plate is available on most kits that can utilize them (MacPherson style OEM suspension). The TSP Racing camber plate will allow a maximum of 3 degrees of camber adjustment depending on the kit.

SAE9254 Steel Springs

Cold roll formed, anti-deformed with its excellent steel property and prolonged life span.3 main styles are used; linear, s-barrel, and v-barrel

Springs are marked with their length and spring rate in mm-kg/mm for example 220-07 os a 220 mm long spring with 07kg/mm spring rate.

French TOTAL Rotary Dedicated Oil

Corresponds to more changing stroke, stable properties can delay the recession, and remain similar viscosity even at extremely high temperatures.

NOK Oil Seals

We use the same NOK Oil seals as Tein. They are used for Anti-attrition and spoilage after long-term usage. Reducing the problem of oil leaks.


Lower Mounts/Base

The lower mount is where our suspension bolts to your wheel hubs. Each lower mount is designed to be an OEM replacement. We provide any and all OEM mounting points and brackets that were on the OEM shock. The lower mount, and the upper mount, is where reverse engineering the OEM suspension plays its biggest role. The process ensures everything is welded and mounted in OEM positions so that your brake lines, wheel speed sensors, and harnesses are a direct fit. Our lower mounts, whenever possible, are made of seamless steel tubing and all brackets are hand welded. Once the lower mount is completed, it is then sand blasted and powder coated in order to prevent rust and corrosion.

Shocks

We are now at the center point of our kit. As you can imagine, we have a wide variety of shock types, lengths and diameters. Each vehicle depending on our data from R&D, and accounting for the OEM suspension design will utilize a different style of shock. Each shock is hand assembled in our factory and dyno tested before use in our kits. This also helps to ensure there are no oil leaks or noise. Shocks are paired together by their compression and rebound numbers after dyno testing to a 3% variance from side to side. This means that in your kit, the fronts and rears are paired almost exactly the same to ensure proper ride quality and performance of the suspension. Each shock is coated in black via EPD, which provides a cohesive appearance, and to help with corrosion resistance.

Adjustment Rings

Height adjustments are made with separate CNC-Machined locking rings for accuracy and smooth adjustment with separate damper shock length adjustment to retain full-stroke and allows for precision suspension tuning. The wide range of allowable ride-height adjustment allows for a conservative drop to more aggressive ride heights for an aggressive stance, or to fine tune your suspension for the circuit to gain full potential of your vehicle's handling capabilities.

Our basic lock ring is located under the spring seat. This ring is special because its primary function is to torque against the spring seat and lock it in place. The lock ring will torque and secure itself to the spring seat securely once properly tightened so that the preload does not change unless the customer decides to make a change. The spring seat and basic lock ring are the two rings that are responsible for gaining leverage to make height adjustment for our coilover systems. Please note that you do not turn the rings independently to adjust height, you simply use them as a leverage point to rotate the shock body into and out of the lower mount to adjust height, but they must be locked together to achieve this.

The lower lock ring is tasked with keeping the shock locked into place once final ride height is selected. The lower lock ring must be loosened before making any sort of height adjustment and locked down properly afterwards using our spanner wrenches.

If you want to lower the vehicle, you spin the spring seat clockwise to thread the shock body into the lower mount.

 

 

Tools

Tools that are included in the kit are the spanner wrenches and your adjustment knobs. These tools are what give you the ability to really customize and tune your new suspension system.

The Spanner wrenches are a crucial tool in adjusting the ride height of your vehicle. They allow you to adjust the position of the shock inside the body and insure the tension on your spring.

The adjustment knobs are used to help you customize the overall feel of your ride, whether your damping is soft or firm.

On G-Racing coilovers with 32 click adjustment your recommended settings are;

17-32: Suggested for track use.
9-16: Suggested for mountain/aggressive use.
1-8: Suggested for common street use.

On G-Street Coilovers with 24 click adjustment your recommended settings are;

17-24: Suggested for sportier/aggressive use.
9-16: Suggested for spirited driving use.
1-8: Suggested for common street use.

 

Warranty

TSP Racing coilovers come with a 1 year unlimited mile limited warranty that covers all the main shock body components.

6 month warranty of consumables like rubber top mount, end links, etc

Camber plates are not covered under this warranty and have warranty because of the metal on metal contact.

All kits are completely rebuildable and individual parts are available separately for purchase.

Talon T. from Montana

These are great. Took a little long to get but I got the first set of TSP G-Street Coilovers. I use them daily and finally broke in. Perfect for my area. No more body roll. Awesome control. If I need to change my ride height for winter mode I can easily. Thank you TSP.

Adam H. from Illinois

Seem to be built pretty good and would rate quality 7 outta 10 
Install was straight forward and everything fit perfect will rate 10/10 for install and fitment
Ride quality is good and will need to adjust the dampening again so I will rate the ride quality 7/10 
All in all very happy with the coilovers and would recommend to anyone

About the TSP brand

After quite a few years of research and networking with the industry's best manufacturers, and fabricating and building some prototype parts, TruSpeed Performance decided to launch the TSP brand early 2016. We decided to start with a focus on Suspension and Alignment parts as there are so many companies out there increasing and tuning engines but many often neglect tuning the suspension. Not only does a car need to go fast, but it needs to handle as well. We decided to start by offering quality coilover systems for a large variety of vehicles. After a good amount of searching and negotiating, we decided to work with a company out of Taiwan who was putting out an impressive product and that had over 10 years of experience building suspension systems for other major companies. We were impressed by the quality of the materials used, and their willingness to create and customize applications for our customer's needs. We are constantly expanding the applications that are well over 700 at this point.

We plan to continue to grow the brand and are already putting out our Tru-Align Alignment systems to compliment and help best utilize the power of our TSP Racing G Series Coilovers.
