HKS HIPERMAX MAXIV SP Drag for Toyota Supra '20+ hks80250-AT003D

Toyota GR Supra has a launch control to allow an excellent start. The stock suspension is set to assure traction in front and rear for multiple situation. 

However, the MAX IV SP DRAG is specifically designed to provide traction on the rear tire and firmly 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 as it has effect on another spring.

The special billet aluminum upper plate at rear shock was made lightweight and the straight wound spring was used at both front and rear that allow for easy spring rates change.

HKS used the latest technology in this m HIPERMAX MAXIV SP Drag for the best performance in this modern DRAG scene.

F=59(6) / R=98(10) Spring Length (mm) 

F=200(straight wound) 

R=250(straight wound)

F=-22(-17 to -65) / R=-20(-12 to -75)

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

Since the design is based on the assumption of DRAG race, mechanical noise may occur during stroke. 

In addition, please be aware that the front grip may decrease during acceleration.
