XYZ Racing Super Sport Coilovers — BMW 5 SERIES E34 6 CYL φ55 welding 1987-1995

The E34 5 Series carries its straight-six up front and a kerb weight north of 1,400kg, which means the factory dampers were tuned for motorway comfort rather than for holding a line through a fast B-road sweeper. Body roll under load and a soft transition into oversteer off the semi-trailing arm rear are the two traits every E34 owner learns to manage, and they’re exactly what a stiffer, adjustable damper is built to address.

XYZ Racing’s Super Sport coilover for this φ55-welding fitment replaces that setup with a damper you can tune to the car and the road, rather than one fixed compromise from the factory. It’s built for fast-road driving with regular track days mixed in, not a full-time circuit car, which suits an E34 that’s as likely to do a motorway run on Friday as a track day on Saturday.

What this coilover does for your 1987-1995 Bmw 5 Series

Drop the ride height and you immediately lower the centre of gravity on a saloon that was never short of one, cutting into the body roll that shows up first in this chassis under hard direction changes. The 36-way damping adjustment lets you firm up compression and rebound independently of that ride height change, so you can control how quickly the rear settles after a load transfer without turning the ride brittle on the road home. Because the front end carries the six-cylinder engine’s weight, adding extra low-speed compression at the front axle sharpens turn-in and cuts the nose-dive under braking that the standard front struts allow. Set softer for the commute and firm up before a track session, and the car stops feeling like it’s fighting its own mass mid-corner.

About the Super Sport coilover

Super Sport is XYZ Racing’s damper for owners who want one set of hardware to cover daily driving and weekend track use without switching parts between the two. The damper body carries 36 stages of adjustment, giving a genuinely usable range between a comfortable setting for rough UK B-roads and a firmer one for circuit work, rather than a handful of coarse clicks. Ride height is independently adjustable on the damper body, so you can set the car’s stance and corner weights without touching the compression and rebound settings you’ve already chosen. Construction is built around monotube internals for consistent damping force as the oil heats up over repeated hard use, which is the difference between a damper that holds its character through a track session and one that fades by the third lap. For this E34 φ55-welding application, the strut is prepared for the welded 55mm mounting this chassis requires rather than a bolt-in top mount, so fitment matches the car’s original strut architecture.

Fitment for the Bmw 5 Series (1987-1995)

This kit is built for the E34-generation 5 Series, chassis code BM12, across the 1987 to 1995 production run for six-cylinder models using the φ55 welding strut mount. Confirm your car uses the welded 55mm strut design before ordering, as this fitment is specific to that mounting type rather than the standard bolt-in variant.
