Wondering what the FR-S owners think of these?

DYNAMIC PRO SPORT coilovers are designed and developed for all motoring enthusiasts wanting excellent handling without sacrificing comfort. This suspension system features 33-way adjustable dampening settings and full length adjustment to meet every driver’s handling desires. Pillowball mounts and adjustable camber plates are included for front and rear on most kits to increase steering response, while aluminum upper mounts with hardened rubber bushings are used on some applications for noise reduction. This suspension system is ideal for daily driving and occasional track use.

High quality components are adopted to ensure product durability and stability. Each application is fully test fit and completely road tested to guarantee all our customers perfect performance and comfort.


33-WAY DAMPENING ADJUSTABLE

This suspension system features 33-way dampening force adjustment (compression/ rebound). A wide range of dampening adjustments can be made to provide a variety of responses to different road conditions and to tune the ride feel.
MONO TUBE INTERNAL DESIGN

15 month limited warranty on insert
The needle valve piston (material imported from Sweden) is utilized to make the steering more agile and to stabilize the vehicle. A high rigidity 52mm shock body with extra oil capacity enables the cushioning force to have optimal linear change. We use highly reputable seal brand – NOK, whose seals can withstand high temperatures and prevent oil leakage. The piston rod is made from high quality S45C steel and is processed with Thermal Refining and High-frequency Induction Hardening Treatments for rigidity and durability. YELLOW SPEED’s commitment is to ensure safety and to provide high quality products, hence the shock stroke movement has been tested 10 million times on advanced testing equipment; this amount of testing is equal to a vehicle with 5-years of mileage. Each component of the suspension system is rigorously inspected and strictly tested by YELLOW SPEED to avoid any failure. Our commitment to continual driving improvement goes beyond
SPRING BEARING MOUNT

PENDING PATEN
Spring bearing is mounted between the spring and the top cap to make the handling more agile and to eliminate the spring noise caused by car cornering. This design enables the spring and the shock to perform together more effectively. Clean and grease the spring bearing periodically to prevent from rust or corrosion, which can make the spring bearing last longer.
HIGH RIGIDITY STEEL SPRING

The spring is made from high quality SAE9254 steel for optimal durability and high tensile strength. The spring rate remains unchanged and undeformed even after the spring has been subjected to long term wear and even if compressed or extended.

ADJUSTABLE SPRING SEAT

In addition to the lower bracket, the vehicle ride height can be adjusted by the spring seat as well. The spring seats are made from forged aluminum for durability and rigidity.
SHOCK BODY

Shock body is coated with Electroplating treatment to prevent rust and corrosion.
FULL LENGTH ADJUSTABLE

A steel lower bracket is utilized for MacPherson strut type to increase rigidity for safety (where applicable). For some MacPherson strut models, the brake line bracket is welded manually perfectly to the steel lower mount. A high quality forged alloy aluminum lower bracket is used for Double-A Arm strut type (where applicable). The steel/aluminum lower bracket is processed with electroplated/ anodized surface treatment to prevent corrosion or rust in the harsh conditions of motor sport. The vehicle ride height can be adjusted easily with the lower bracket by winding up and down to drop and raise. With the lower bracket, it allows maximum suspension travel without affecting the shock stroke.
LOWER LOCKING COLLAR

It is made from forged 6061 aluminum for increased strength and rigidity.
DEVELOPED DAMPING OIL

Our formula damping oil contains high quality deformer to prevent foaming, and the viscosity remains unchanged under any working temperature conditions to ensure that all internal components perform perfectly.

i know this thread was from a while back but wanted to add some info for others wondering the same thing. yellowspeeds are pretty much like ksport and D2, just another taiwanese coilover. They are used in D1gp though and arent really that bad at all. It's something i would put on my personal vehicles.
