Point

Sports type suspension design based on MAX Ⅳ GT for high-grip radial tires is available for JAZ80 Supra.
The product has been designed through the full use of HKS' latest technologies. To determine the final specification, extensive product testing was performed to ensure compatibility in both high ride quality for everyday driving and better handling for circuit driving. A new valve combined with the latest piston design and an all new low resistance and compliant bump rubber all work together to produce a ride which is at a new level from previous designs. While unnecessary movement is minimized on the high ways or winding roads, the smoothness on gaps and bumps on the road maintains high driving comfort and excellent grounded feeling, which invites drivers step on the accelerator with confidence. ...
