Point
Hipermax IV GT suspension gives GR vehicle an improved drivability on top of an expected comfort of stock suspension. Driving this car will be more fun with the new suspension kit.
Rear damper use an in-house made original rubber bushing, it employs a new adjustment dial for wide setting range of damping force. With it now it’s possible to make adjustment according to different driving situations. With use of helper spring, now it’s possible to use universal straight spring as well.
In case if front spring rate to be increased it’s possible to use helper spring. We recommend doings so, as it allows to make fine adjustments of stroke.
Please be careful, if front case length is lowered more than 325mm tire might come it contact with fender when driving.
Rear lower lock seat was moved above the ride height one, rubber seat on top of the ride height seat was removed.
