XYZ Racing Tarmac Rally Coilovers — BMW 3 SERIES E93 4 CYL 2006-2011

The E93 convertible carries weight and body flex that its E90 saloon and E92 coupé siblings don’t – the cut roofline costs torsional rigidity, and a standard-set 4-cylinder E93 shows it the moment the road surface turns rough. On a sealed tarmac stage, where crests, compressions and mid-corner ruts arrive at speed rather than the smooth, repeatable apex of a circuit, that extra scuttle shake and body movement becomes the limiting factor long before the engine does.

The XYZ Racing Tarmac Rally coilover kit for the BMW 3 Series E93 4 CYL (2006-2011) is built around that exact problem. It’s a damper set with a stage-rally brief, not a track-day one – control over sustained, high-frequency surface impact rather than late-braking grip on a rubbered-in circuit line.

What this coilover brings to your 2006-2011 BMW 3 Series E93 4 CYL

Fitted to the E93, the kit’s first job is absorbing the hit from uneven pavement and larger compressions without passing that impact straight into the convertible’s less rigid shell. Where a soft factory damper lets the body pitch and wallow over a stage’s rougher sections, this setup suppresses that shock body movement so the tyre stays loaded and in contact rather than skipping across the surface. On a 4-cylinder E93 – lighter over the front axle than the 6-cylinder cars – that translates into more usable front-end traction under braking into a rough right-hander, and a rear axle that settles rather than hops when the surface breaks up mid-corner. The net effect on your car is a chassis that holds its line through compressions instead of getting deflected off it, which is what lets you keep your foot in where a standard-set E93 would have you lifting.

About the Tarmac Rally coilover

XYZ Racing built the Tarmac Rally damper specifically to soak up the punishment of sealed-stage rally surfaces – the big hits, the broken tarmac, the mid-corner compressions that a circuit damper isn’t calibrated for. The internal damping curve is tuned to absorb that impact rather than transmit it, cutting the shock loading through the body structure and keeping the tyre’s contact patch working instead of skittering across the surface. That control is what XYZ describes as delivering real stability through a corner – the car staying settled and predictable rather than moving around underneath the driver. The settings baked into this kit come directly from XYZ Racing’s own tarmac rally programme, so the damping behaviour reflects what the team has learned running these stages rather than a generic road-going compromise.

Fitment for the BMW 3 Series E93 4 CYL (2006-2011)

This kit is built for the E93 convertible with 4-cylinder engines, chassis code BM68, covering the 2006 to 2011 model years. Confirm your car’s chassis code and engine configuration against your logbook before ordering, as coilover geometry differs between the 4-cylinder and 6-cylinder E93 variants.
