This spring set will lower your car both front and back, which will reduce body roll and improve both handling and look. The change will be especially noticeable on 1975-85 Spiders which were raised in the rear due to bumper height standards. Approximately 15% stiffer than the stock springs. Rear springs are progressive rate, which means they are softer on small bumps, but become stiffer when the suspension is compressed more.
These springs will level out the stance of the car
Once installed most Spiders with stock diameter tires will have the top of the front wheel arch just under 24" (61cm), and the rear just over 24" from the ground.
Note: the progressive rear springs may make noise during driving, in that case use our spring sleeves to resolve the issue: SU0-007
