PREMIUM COMPETITON coilovers are designed and developed for use in most motorsports. Through years of competition and testing, we have made uncountable improvements in setup for racing use in order to provide the most durable and competitive damper. Spring rates and shock valving are made for competition to make the vehicle more controlled and balanced.

This suspension system features 33-way dampening adjustment and full length adjustment to accommodate every driver’s needs. The lower mounts are manufactured from lightweight alloy aluminum to reduce unsprung weight. The pillow ball top mounts are used on McPherson struts for maximum handling and performance.

When placing your order please specify what type of racing the vehicle is used for. The PREMIUM COMPETITION coilovers are spec built and setup different for each type of racing.

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 ride feel.

PILLOW BALL UPPER MOUNT W/ ADJUSTABLE CAMBER PLATE

The pillow ball mount with camber plate is included on the front and the rear to offer direct and complete handling response (not available for some applications).

MONO TUBE INTERNAL DESIGN

The needle valve piston (material imported from Sweden) isutilized to make the steering more agile and to stabilize the vehicle. Spring rates and shock valving made for competition are significantly different from the ones for road use. High rigidity 52mm shock body 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. 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 words.

HIGH RIGIDITY STEEL SPRING

Spring rates and shock valving made for competition are significantly different from the ones for road use. All springs are produced from high quality SAE9254 spring steel for optimal durability and high tensile strength. The spring rate remains unchanged and undeformed, even after the spring has been used for a long time, 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.

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

High-viscosity formula damping oil for competition is used for oil molecule protection against the highest temperatures to last the lifetime of the damper or longer.
