Product Specifications
Built for the iconic BMW E30 3 Series (1982-1991), this Street Series coilover kit delivers a confident stance and tightened handling without sacrificing daily drivability. The signature purple anodized aluminum top mounts add a motorsport-inspired visual touch that stands out on the lift, while the twin-tube damper paired with calibrated 6/8 kg/mm springs keeps the ride composed whether you're commuting or carving back roads.
Designed as a direct bolt-on replacement for the factory suspension, the kit lowers your E30 between 5-8cm (2-3 inches) with threaded height adjustment, letting you dial in the perfect look. Front camber plates are adjustable — a real performance advantage for correcting alignment after lowering or for track-day setup. Compatible with the full range of E30 sedan powertrains including the M20 inline-six, M40/M42 four-cylinders, and M21 diesel (324D/324TD).
For RWD models only. Not compatible with M3 or non-sedan body styles. If you drive your E30 hard, this kit is your foundation — the rest of the build follows.
