Product Description

The HKS 80280-AT001 HIPERMAX Touring Adjustable Spring Kit is engineered to deliver both performance and versatility for the Toyota GR Supra (A90/A91) with adaptive electronic suspension. Unlike fixed lowering springs, this adjustable spring kit works with the vehicle's stock adaptive damping system, allowing you to lower ride height while retaining comfort and control. The variable-pitch spring design improves chassis stability and handling dynamics for spirited driving, whether on twisty roads or daily streets.

This height-adjustable kit provides a broad range of ride height settings - enabling up to roughly **-25 mm to -52 mm** at the front and **-24 mm to -57 mm** at the rear compared to stock - so you can fine-tune stance and performance. HKS also includes reinforced bump rubbers and specific dust boots designed for lowered suspension applications to enhance durability. Installation requires some modification of front bump rubber, and this part is optimized for adaptive suspension variants of the GR Supra. With sport-oriented spring rates and precise engineering, the 80280-AT001 improves handling posture and driving confidence without compromising ride quality.
