APR Roll-Control Lowering Springs are designed to improve handling while delivering a stylish visual upgrade to the vehicle. This simple, yet effective upgrade lowers the vehicle’s center of gravity, giving it an attractive new stance while remaining fully compatible with the OEM dampers. In doing so, body roll is reduced and handling improves without sacrificing ride quality or greatly impacting the life of the OEM dampers. Each spring is manufactured using premium material and the latest high-end techniques to ensure they resist sagging and withstand harsh track conditions for years to come.
APR Roll-Control Lowering Springs' spring rates are only slightly stiffer than OEM. Using an even stiffer rate would sacrifice ride quality and could also cause the system to be underdamped which would be a detriment to performance. Both the ride height and spring rate are designed in parallel around the criteria of keeping the OEM dampers and maximizing performance while maintaining OEM like ride quality.
