XYZ Racing Super Sport Coilovers — BMW 3 SERIES E30 4 CYL OE φ45 (Front Welding OE Rear Separated) 1982-1992

The E30’s four-cylinder front strut mounts a φ45 OE-diameter housing that XYZ Racing’s Super Sport kit replaces with a welded front assembly matched to a separated rear damper, keeping the factory geometry intact while opening up 36-way damping adjustment. On a chassis this light, small changes at each corner show up immediately in how the car turns in and settles, which is exactly where Super Sport is built to work.

This is a fast-road and weekend track spec, not a full race setup. It’s aimed at E30 owners who drive the car regularly and want a firmer, more controlled platform for the odd trackday without living with a harsh daily ride.

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

Ride height adjustment lets you correct the E30’s factory stance and set corner weights properly, which matters on a car this old where original springs have usually sagged unevenly. The 36-way damping range gives you a wide enough window to run the car soft for motorway miles and stiffen it up for a track session without swapping parts. Because the front uses a welded φ45 housing rather than a bolt-in cartridge, the strut assembly sits stiffer in the towers, so damping changes translate more directly into what you feel through the wheel instead of getting soaked up in the mount. At the rear, the separated damper design keeps spring and damper forces distinct, which on the E30’s semi-trailing-arm rear end helps keep the axle load consistent through mid-corner rather than letting the whole assembly move as one compromised unit. The net result on a lightweight, rear-drive chassis like this is sharper direction changes and less body roll without the ride turning brittle.

About the Super Sport coilover

Super Sport is XYZ Racing’s damper built to take the harshness out of rough tarmac while still giving a real adjustment range to work with. It runs 36-way damping adjustment alongside independent ride height control, so the same kit can be wound softer for potholed B-roads or firmed up for a circuit without changing components. The construction is aimed at cars that see both daily use and the occasional weekend at the track, rather than being a dedicated race-only product – it’s built to be lived with, not just driven hard once a month. For the E30’s OE φ45 front-strut layout, XYZ Racing engineers the housing to weld directly into the factory strut, preserving the original geometry rather than forcing a different top-mount arrangement, while the separated rear damper is sized to match the E30’s own rear suspension design.

Fitment for the Bmw 3 Series E30 (1982-1992)

This kit is built specifically for the 3 Series E30 4 CYL OE φ45 chassis with front-welding construction and a separated rear damper (chassis code BM05-1), covering the full 1982 to 1992 production run. Confirm your car uses the OE φ45 front strut diameter before ordering, as E30 variants differ in strut sizing across the range.
