*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

It was tested with Yokohama Advan A052 tires on Fuji Speedway Racing Course.
This kit has a higher sport driving performance than the factory electronic controlled shock absorber.
By properly balancing the match between the high-grip tires and the GR Supra's strong body rigidity, we have achieved to bring out the best stable riding of Supra.
Newly adopted high-spec springs provide all-around coverage from street driving comfort to track. They provide such comfort that you may forget that high-rate springs are installed.
The front suspension adopts "inverted" strut type. The cylinder and outer diameter are penetrated into the upright mounting area to secure the necessary stroke volume even at a lowered ride height.
Adjustment type pillow upper allows to adjust the camber angle.
The rear coilover is equipped with a special upper plate machined from aluminum, and weight reduction is taken into consideration after determining the areas where strength is required.
*A separate error canceller is required due to the removal of the electric shock absorber.
