Thinking to upgrade your GT-R handling, and I advise that you upgrade with a COBB Tuning Coilover Sleeve System. Adding the COBB's Tuning Coilover Sleeve System your GT-R handling will improve dramatically. The best GT-R replacement for the factory springs, is the lightweight performance COBB Tuning's Coilover Sleeve System that improves handling, reduce body roll, and do not negatively impact ride quality. The COBB Tuning's Coilover Sleeve System offers you the best way to lower your ride. COBB Tuning's new Coilover Sleeve System gives you the ability to customize the ride height of your Nissan GT-R while retaining the factory adjustable shock absorbers.

The COBB Tuning's Coilover Sleeve System suspension movement has also been enhanced by replacing the stock rubber bushings with Teflon-lined FK spherical-bearing top mounts that allow for full articulation of the suspension while maintaining linear spring movement. COBB Tuning's Coilover Sleeve System handling is dramatically improved by utilizing 700 lb/in front springs and a 600 lb/in rear spring and helper spring combination to keep the rear spring seated through the full range of motion. COBB Tuning's custom spring rates are also available. Gold anodized aluminum spring perches were designed to facilitate easy installation and adjustment with the use of the included black zinc-plated, hardened-chromoly steel 3 in 1 tool. The custom designed tool is used to change ride height, install upper perches, and to lock lower perches in place. Black anodized aluminum threaded mounts, stainless steel spacers and bump stops complete the system.
