*1. Height from road surface to fender arch.
*2. Height at factory is the data tested at HKS with the setting of Full Kit. (HKS' recommended setting.)
*3. Adjustable range (However, the lowest value may not be road legal.
Even within the adjustable range, car body, arm etc. may contact. In such case, it will be hard to drive.
Damper oil leakage or any other problems caused by low ride height setting from the factory setting will void the warranty of the product.)
*4. Drivable range that there is no contact of car body or arms etc. (However, change of tire/wheel size may cause a problem.)
Caution). Actual data depends on each vehicle.

Point
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 situation.
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 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.
 
* This kit requires the error canceller of the stock electric shock absorber.
