Product Details
These Ground Control coilover conversion kits fit the 1986-1992 Mazda RX-7 RWD.
Ground Control Coilover Conversion Kits for the Mazda RX-7 add adjustable ride height and corner balance. The threaded spring perch system lowers the car and reduces body roll, and it works with stock or aftermarket struts.
Every kit is hand-built in the USA and backed by a lifetime guarantee on the complete assembly, not just the springs. Ground Control is the West Coast distributor for Eibach ERS race springs, which are warrantied for life against sag and rate change. The anodized 6061-T6 aluminum adjusters lock securely under load.
