Nitron - NTR R1 2-Way Coilover Suspension Kit - BMW E9X M3

The NTR R1 system offers unrivaled performance and value with a design that gives drivers a wide range of effective, easy to use damping control.

2-Way combined damping adjustment. Developed from our full race suspension and sharing many components with the R3 system, the R1 offers exceptional performance, reliability and value for both road and track use. Widely praised by drivers around the world and respected for out-performing considerably more expensive suspension kits.

R1 kits provide uncompromising quality, reliability and performance without the need for a remote canister. Fade-resistant and hand built with ultra-low friction components, the R1 shock is made to last on the road and track. The high-grade materials protect against corrosion whilst reducing weight. Every R1 kit is custom built, sprung and fully serviceable. Titanium and hard-anodized parts are hand built to last not only season after season, but also the harshest of winters.
