Concept
- GR Supra has a launch control to allow an excellent start. However, the stock suspension is set to assure traction in front and rear for multiple situations. The MAX IV SP DRAG is specifically designed to provide traction on the rear tire and maintain that traction.
- Bump rubber is attached to the rear shock in order to cope with the higher power and higher grip expected in the future. Bump rubber has the effect of a another spring.
- The special billet aluminum upper plate at rear shock was made lightweight after identifying the part that need strength. - The straight wound spring is used at both front and rear allowing to easily change spring rates.
Features:
- The full-length adjustable suspension allows the stroke ratio (bump touch timing) to be changed without changing the vehicle height. Adjusting the shock length of the rear shock to a shorter value can delay the bump touch timing and increase the nose-up angle.
- In a HKS internal test, HKS factory shock length settings can perform shorter drag time. Furthermore, it will be more competitive after the adjusted shock length of vehicle posture is properly setup for the unique vehicle and track.
- Also, HKS used launch controls to test for time differences. As a result, it was confirmed that a time of 0 -100 km has an advantage of about 1 second. It was also confirmed that the loss was suppressed by the traction applied to the rear tire in the zone inducing a wheel spin.
