The main objective of this kit is to provide more rear grip on lowered car. Either if its needed to maintain speed with high lock angles in drifting, to get a better start in drag racing or just being faster in circuit racing. Higher roll center (RC). Lowering the car is very important to increase performance and handling, but this would mess up the original factory designed kinematics. It lowers the roll center and increases camber gain.- On Wisefab Supra rear suspension the RC is brought back in normal range on lowered car providing higher roll stiffness. Less camber gain. Supra rear suspension has already a lot of camber gain at original ride height. With lowered car the camber gain gets even bigger. If the car would have only roll motion, then a lot of camber gain wouldnt be too bad, but during bump motion the camber would change a lot, which would decrease grip. On Wisefab setup the camber gain is decreased to provide a better grip. Anti-squat. Original Supra rear suspension has some negative anti-squat. That means the rear would squat a lot during acceleration. Anti-squat is changed to slightly positive to provide more stable motion at rear. Adjustable spring and shock absorber motion ratio. The shock has 3 attachment possibilities on rear arm, which allows to change suspension stiffness and handling very quickly without changing the spring and messing up ride heights. Other components, packaging and clearance. Hub to hub length (track) is the same as original, as this is defined by halfshaft lengths. This kit assumes coilovers to have enough clearance. Ride height is designed to be ~80mm from front subframe to ground and rear according to front Dependent on rim width and ET, inner wheel wells need to be slightly modified. Minimum rim size is 17‰. We have tested the kit with 9,5‰x18‰ ET 35 Maximum tire size that is tested is 265/35 R18 The kit is designed and manufactured the way that after installation and toe adjustment its ready to use right away. For racing use only! Happy drifting!
