YELLOWSPEED has been working with our racers and tuners dedicating to this second-to-none 2-WAY and 3-WAY PRO PLUS RACING suspension system over a number of years. With extensive development, engineering, testing, modification and actual racing competition experiences, 2-WAY and 3-WAY Pro Plus Racing coilovers enable you or teams to fine tune for any track/circuit race, endurance race or circuit lap record competition. Racing tire is recommended with this product for more outstanding performance & score.
2-WAY PRO PLUS RACING coilovers feature separate adjustable compression and rebound damping settings and full length ride height adjustment.
2-WAY EXTERNAL CANISTER
The outstanding feature to 2-way Pro Plus Racing suspension system is external canister allowing you to adjust the rebound and compression damping separately. The canister comes with either hose or piggyback depending on application.
2-WAY PRO PLUS RACING SUSPENSION SYSTEM FEATURES SEPARATE REBOUND & COMPRESSION DAMPING SETTING
This 2-way 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 For suspension systems utilizing a Double A-Arm strut type, either pillow ball upper mount (without camber plate) or aluminum upper mount is available, our customers can select what they need at their decision. This coilover kit is supplied with aluminum upper mounts if customers do not specify when placing an order with us. For suspension systems utilizing a MacPherson strut type, this coilover kit comes standard with pillow ball mounts with adjustable camber plates fronts and rears (where applicable).
MONOTUBE RACING SHOCK DESIGN
The needle valve piston is utilized to make the steering more agile and to stabilize the vehicle. In addition, motorsport spec piston with racing flow design has been developed and is integrated into this racing product. Spring rates and shock valving made for competition are significantly different from the ones for road use. A high rigidity 52mm shock body used for MacPherson strut type for extra oil capacity enables the cushioning force to have optimal linear change. High quality oil seals are utilized to withstand high temperatures and to prevent oil from escaping. 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 YELLOWSPEED 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 steel for optimal durability and high tensile strength. The spring rate and shape remains unchanged and undeformed, even the spring has been subjected to long term wear.
FULL LENGTH ADJUSTABLE
A steel lower bracket is utilized for MacPherson strut type to increase rigidity for safety (where applicable). For most 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 motorsport. 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 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 TOP
Spring bearing top is mounted under the pillowball mount 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.
