Description

The SP Motorsports Spring kit provides four main and four helper springs to stiffen the chassis of your GT3RS. These springs are a direct-fit performance modification for the factory damper assembly. They increase response rate and stability during aggressive driving. This is especially beneficial when running a lowered ride height, smaller aftermarket wheels, or increased aerodynamic downforce.

Choose between our Standard setup at 108 N/mm front and 128 N/mm rear, or the EVO setup at 128 N/mm front and 147 N/mm rear. Each option is designed to suit individual driving styles and ride height preferences.
