*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.

・This product was designed to provide the performance to allow faster and comfortable driving on winding roads to circuits while maintaining supple driving feeling attained by Hipermax IV GT.
・Matching test for use of 052 high grip tires was conducted in a short course of Fuji International Speedway. Settings was determined by careful analysis of the vehicle fine movement.
・The front bracket was specially designed for Hipermax SP to maintain the initial camber and the vehicle height adjustment with the sufficient stroke adjustment range after increasing the spring rates.
・Utilizing the helper springs in the front side enables higher degree of freedom of vehicle height setting and stroke distribution. Rubber sheet and thrust sheet are equipped with the spring for easier adjustment.
・For the front upper mount, a new camber adjustable pillow upper was specially designed for ZC33S and is equipped with the front side that enables direct handling and higher degree of freedom in settings.
・The rear springs were specially designed for ZC33S to implement the sport performance and vehicle height together in a high level.
・The ID65 ride height adjuster is replaceable with the universal ID65 springs. (Replacing with a universal spring voids the warranty.)
・The internal parts were designed to widen the damping adjustment range of the dial. The optimal performance for a various driving scene is allowed.
・The clearance between the front damper, tire, and wheel is narrow, use spacers to avoid unnecessary contact.
・When adjusting the camber, make sure unnecessary contact does not occur since the ABS sensor installation bracket inside the fender is very close to the camber. Lowering the case length approximately 10mm may avoid the occurrence of unnecessary contact.
