XYZ Racing Super Sport Coilovers — BMW 3 SERIES E30 4 CYL OE φ51 (Front Welding Modified Rear Integrated) 1982-1992

The E30’s four-cylinder cars carry noticeably less weight over the front axle than the six-cylinder versions, which is exactly why the standard OE φ51 strut geometry rewards careful spring and damper matching rather than a generic drop. The XYZ Racing Super Sport coilover kit for the Bmw 3 Series E30 4 CYL is built around that reality: a front conversion that welds onto the OE φ51 strut housing and a rear kit that integrates spring and damper into one unit, replacing the E30’s separate rear components.

For an owner splitting their time between fast-road driving and the odd track day, that rear integration matters more than it sounds. The E30’s semi-trailing arm rear axle is sensitive to ride height and preload, and a properly matched damper stops the rear end wandering under trail braking into a corner.

What this coilover does for your 1982-1992 Bmw 3 Series

Ride height adjustment lets you correct the E30’s factory stance and drop the centre of gravity without resorting to cut springs, which keeps suspension geometry and damper travel intact. The 36-way damping adjustment means you can run a soft, compliant setting for a motorway trip to a track day and firm the front and rear up separately once you’re on circuit, rather than living with one compromised setting all week. On a car this light, small changes in damping force are easy to feel through the wheel and the seat, so the range on offer here is genuinely usable rather than decorative. The welded φ51 front conversion keeps the factory strut mounting points, so the geometry changes stay limited to ride height and spring rate rather than introducing new camber or caster errors. Combined, the kit lets a four-cylinder E30 carry more front grip into a corner while keeping the rear settled on the way out.

About the Super Sport coilover

XYZ Racing’s Super Sport line is built to take the harshness out of poor road surfaces without turning the car soft, which is the balance a fast-road E30 needs more than an all-out track spring rate. Ride height is adjustable independently of the damping, so lowering the car doesn’t force a compromise on preload or bump travel. The headline spec is 36 stages of damping adjustment, giving a genuinely wide window between a comfortable daily setting and a firmer one for repeated hard driving, rather than a token handful of clicks either side of a fixed middle. Construction suits both the front φ51 welded conversion and the rear’s spring-and-damper-in-one layout, so the whole car is matched to a single design philosophy rather than mixing damper types front to rear. It’s built for owners who want one car to do the commute and the weekend track session without swapping parts in between.

Fitment for the Bmw 3 Series E30 4 CYL OE φ51 (Frt Welding Modified Rr Integrated) (1982-1992)

This kit is specced for E30-generation 3 Series cars fitted with the four-cylinder engine range built between 1982 and 1992, using the OE φ51 front strut diameter. The front fitment is a welding-modified conversion onto that φ51 housing, and the rear uses an integrated spring-and-damper unit in place of the separate OE components, so confirm your car’s front strut diameter matches φ51 before ordering.
