55mm Damper System

This advanced system offers an extended stroke, robust internals, and a unique design that allows for simultaneous adjustment of both compression and rebound damping. Large 55mm shock bodies house oversized pistons, increasing oil capacity to improve cooling during intense use. The kit includes carefully selected spring rates and damping settings tailored to each application, providing enhanced vehicle stability and superior absorption of uneven road surfaces. Constructed with aerospace-quality aluminum and featuring heavy-duty steel lower mounts, these coilovers are built for durability. The monotube, high-pressure design with inverted steel shock absorbers ensures responsive performance. Front top mounts are pillowball type with camber adjustment, while the rear top mounts are also pillowball type but without camber adjustment. The kit also features adjustable lower mounts and front camber adjustment capabilities. This coilover kit is specifically designed for the 1982-1992 BMW 3 Series (E30) RWD models, including the 318i, 320i, 325e, and 325i, provided they have the 45mm OE front strut. Spring rates are set at 9.8 kg/mm for the front and 7.2 kg/mm for the rear. Please verify fitment details, including the 45mm OE front strut requirement, before purchase.
