HKS MAX 4 GT-A FULL KIT FOR 2013+ SUBARU BRZ ZC6 (hks80230-AF012V)

The HKS MAX 4 GT-A FULL KIT is an "Ultimate Street Damper" developed under the supervision of rally driver Mr. Toshihiro Arai. To provide suspension available for all road conditions (stabilized road-holding performance), the stroke was extended. Tests of the spring bump rubber and damping force were conducted many times to provide the best road-holding performance. Additionally, ride comfort was much enhanced than the existing MAX IV GT. There is a range where the load shift is controlled in a critical area. Without unfavorable understeering and/or sudden oversteering and with reliable traction, high quality and pleasant driving feelings are created to enjoy BRZ for a long time. The best handling dial position Rally driver Mr. Toshihiro Arai selected at the time of testing at Gunsai is 15 for both front and rear. The value within the parenthesis under the stroke section is the stroke length of the bump rubber.

PLEASE NOTE

• Making a slit on the rear interior liner for the rear adjustment dial is required.
