XYZ Racing Tarmac Rally Coilovers — BMW 5 SERIES E28 4 CYL φ52 welding 1980-1990

The E28 5 Series’ four-cylinder cars – the 518, 518i and early 520i – carry noticeably less weight over the front axle than the six-cylinder 528i and 535i, and on a sealed tarmac stage that lighter nose still has to load evenly under trail braking into a hairpin. XYZ Racing’s Tarmac Rally coilover is built around a weld-on 52mm strut collar, so it fits directly onto the original E28 strut housing rather than relying on a factory threaded perch that’s now decades old. That matters on a chassis this age: the strut tube is what you’ve got, and the kit has to mate to it cleanly rather than ask you to source new towers.

This is a sealed-stage rally coilover, not a fast-road comfort kit – the spring and damping combination is set for a car on full attack for a fixed run of stage miles, not for commuting between them. For the 1980-1990 5 Series that means a damper tuned to keep the semi-trailing arm rear axle settled and the front struts controlled when the road surface changes without warning.

What this coilover does for your 1980-1990 BMW 5 Series E28

Fitted to a 4-cylinder E28, the kit’s job is to stop the lighter front end skipping across broken tarmac and mid-corner ridges. The damper absorbs the jolt from a big compression rather than passing it straight into the chassis, which keeps the front tyres loaded and gripping instead of bouncing free. That control carries through to the rear semi-trailing arms too: suppressing body shock through a stage keeps the rear axle’s camber and toe more consistent from one corner to the next, which is where a 40-year-old suspension geometry usually starts to wander. Ride height and preload adjust independently, so you can set stance and corner weights for scrutineering without disturbing the damping settings XYZ Racing carried over from its own Tarmac Rally programme. The result on a stage is a car that stays flat through direction changes rather than one you have to drive around every crest and dip.

About the Tarmac Rally coilover

XYZ Racing’s Tarmac Rally range is built for sealed-surface stage work, where the damper absorbs repeated hits from broken pavement rather than the smoother, more predictable inputs of a circuit. Construction centres on the weld-on 52mm strut collar, which lets the kit go onto older chassis like the E28 without needing OEM strut inserts that may no longer be available new. Internally the valving is set to suppress body shock through a big compression – the kind you get crossing a pothole or a ridge mid-stage – so the impact doesn’t unsettle the car’s line, and the tyre stays in contact with the road instead of skipping across it. XYZ Racing carries its own Tarmac Rally racing experience into the base settings rather than starting from a generic road-going baseline, and vehicle stability through that setup is what lets a driver commit to a line rather than react to one. Height-adjustable collars and rebound control are included, so the kit can be corner-weighted and reset per event rather than fixed at one ride height for the car’s life.

Fitment for the BMW 5 Series E28 (1980-1990)

This kit is specified for the E28-generation BMW 5 Series with the 4-cylinder engine, built 1980 to 1990, using the φ52 weld-on strut collar to mate to that car’s original 52mm strut tube. It is not shared with the 6-cylinder E28 (528i, 535i, M5), which carries a different weight distribution front to rear and a different mounting requirement.
