Club Performance Coilover Application

CLUB PERFORMANCE coilovers feature separate adjustable compression and rebound damping settings and full length ride height adjustment. This suspension system is ideal for all motoring enthusiasts wanting excellent handling when they participate in occasional track day, weekend race, club circuit or less aggressive road competition, but also desiring adjustable damping setups for daily drive without sacrificing ride comfort. With an external reservoir, this system allows for increased oil capacity to dissipate heat superiorly, which enables you to operate this product for long period and improves performance & handling.
EXTERNAL CANISTER
The outstanding feature to this system is external canister allowing you to adjust the rebound and compression damping separately. With an external reservoir, this system provides extra oil capacity to dissipate heat superiorly, which allows you to operate this product for long period and improves performance & handling due to more stable variations in damping rates during the vehicle high speed. The canister substance is made of high grade of steel which can resist high gas pressure. The bottom of the canister is made of 7075 aircraft quality alloy, and is processed with anodized surface treatment to prevent corrosion in the harsh conditions of motor sport.
SEPARATE REBOUND & COMPRESSION DAMPING SETTING
This system has twin piston design, and features 33 levels of separate rebound and compression damping adjustment settings, which allow excellent control and tuning ability. There are 33 clicks available on rebound, and 33 clicks on compression so a wide range of damping adjustment settings can be made to provide a variety of responses to different road conditions.
PILLOW BALL UPPER MOUNT W/ ADJUSTABLE CAMBER PLATE or ALUMINUM UPPER MOUNT
The pillow ball mount with adjustable camber plate is included on fronts and rears of the kit for MacPherson strut type (where applicable) to offer direct and complete handling response. For Double A-Arm strut type, the suspension system comes with aluminum upper mount.
MONO TUBE INTERNAL DESIGN
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 used for MacPherson strut type for 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. YELLOWSPEED’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 YELLOWSPEED to avoid any failure. Our commitment to continual driving improvement goes beyond words.
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.
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.
ADJUSTABLE SPRING SEAT
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 in the harsh conditions of motor sport.
Wave Alloy Steel Thrust Washer
For FRONT MacPherson strut models, wave alloy steel thrust washer is installed between a lower locking collar and a bottom mount. The wave thrust washer can provide a controlled amount of friction between the lower locking collar and the bottom mount to effectively prevent the lower bracket from spinning around or becoming loose.
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.
The spring bearing is consumptive product such as pillow ball bearing, rubber bushing, brake pads, brake rotor, oil seal etc.., and it will be worn out or deformed after having been used for a certain period. Therefore, the warranty does not cover spring bearings or metal shims that go on top and bottom of the spring bearings.
