Product Description

The TEIN S.Tech Lowering Springs (Part No. SKP30-S3B00) are engineered for enhanced stance and handling on select rear-wheel-drive Infiniti coupes. Specifically designed to fit the 2003-2007 G35 Coupe (V35), the 2008-2013 G37 Coupe (V36), and the 2014-2015 Q60 Coupe (V36), this set of springs lowers the vehicle approximately 1.2" at the front and 0.9" at the rear, giving the car a sportier appearance while helping to improve cornering response and reduce body roll.

Built from high-strength Chrome Vanadium SAE9254V material with TEIN's signature green powder coat finish, these S.Tech lowering springs are designed to work with OEM or OEM-replacement dampers for a smooth balance of performance and comfort. The progressive spring rate design helps maintain daily-driving ride quality while delivering sharper handling and a lower center of gravity. Included silencer rubbers (on applicable applications) help minimize noise, and the springs are backed by a 1-year limited warranty against excessive sag and manufacturing defects.
