XYZ Racing Tarmac Rally Coilovers — BYD F3 2008-2026

The Byd F3 is not a chassis you see on a service road at a tarmac rally very often, and that is precisely the point of fitting a coilover like this one. The factory damping was specified for a saloon that has spent most of its life as urban transport in China and selected export markets, which means the standard struts give up long before the front tyres do on a sealed stage. The XYZ Racing Tarmac Rally coilover rebuilds the F3 around a stiffer, more controlled platform without ripping out the rest of the suspension geometry.

Compared with a fast-road kit, this one is set up for the specific brutality of sealed-stage rallying – kerb strikes, mid-corner ridges, crested junctions taken in fourth – rather than for ride compliance on a B-road. If you are building a BY02-chassis F3 for closed-road events or club tarmac stages, this is the part that turns it from a parts-bin saloon into something that holds a line.

What this coilover does for your 2008-2026 Byd F3

The biggest change is bump compliance under load. The Tarmac Rally damper is tuned to absorb the sharp vertical input from a poorly patched stage surface and keep the contact patch loaded, rather than skipping and unloading the way a stock strut will when it runs out of stroke. That means traction on corner exit where the F3 would otherwise spin its inside front and waste throttle.

You will also feel the F3 settling earlier into a corner. The factory car rolls onto its outside front and pushes; with rate and damping properly matched, weight transfer happens once and stays put, so steering response sharpens and mid-corner attitude becomes something you can adjust on the throttle. Ride height is set to give you enough stroke to swallow a kerb without bottoming the spring, which matters more on the F3 than on most modern chassis because the factory suspension travel is generous and the new kit has to preserve it.

About the Tarmac Rally coilover

Tarmac Rally is XYZ Racing’s sealed-stage rally series, drawn directly from the company’s own tarmac rally programme. The damping curves are written to absorb sudden vertical impact – mid-corner ridges, repair patches, the lip of a kerb taken in anger – and to suppress body movement quickly afterwards so the chassis is settled before the next input arrives. The intent is traction first: keep the tyre planted across uneven pavement, then let the driver use that grip.

Construction is geared to repeated stage abuse rather than occasional weekend use. Spring rates and valving are matched to each chassis using data from XYZ Racing’s own rally experience, not a generic catalogue setting, which is why the BY02 F3 specification differs from the saloon kits one shelf along. The kit gives you a stable, predictable platform that lets you commit to a line through surfaces you would normally lift for.

Fitment for the Byd F3 (2008-2026)

This kit is built specifically for the BY02-chassis Byd F3 sold from 2008 through to current production. Mounting hardware, top mounts and stroke are matched to the F3’s MacPherson front and torsion-beam rear layout.
