XYZ Racing Tarmac Rally Coilovers — Buick REGAL (Non GS Model) 2008-2017

The Buick Regal of this generation is an Epsilon II saloon – long wheelbase, soft factory damping, and a chassis tuned for American boulevard comfort rather than stage pace. Drop it onto a sealed-stage tarmac rally surface in standard trim and the body movement that felt composed on the freeway becomes the limiting factor: weight transfer arrives late, recovers slowly, and the front tyres run out of grip before the chassis has settled. The XYZ Racing Tarmac Rally coilover for the 2008-2017 Buick Regal is built to rewrite that behaviour.

This is a damper engineered for sealed-stage rally use on a platform that was never intended for it. The valving and spring rates come straight from XYZ Racing’s tarmac rally programme, which means the kit is set up to soak up kerbs, broken patches of resurfacing and the compression hits that follow a fast crest – without losing the body control that lets the Regal’s nose-heavy front end actually rotate on corner entry.

What this coilover does for your 2008-2017 Buick Regal

On a Regal running this kit, the first thing you notice is how the chassis stops floating. Mid-corner bumps that previously unloaded the inside front tyre are absorbed by the damper rather than the body, so the contact patch stays planted and the steering stays loaded. Over a compression – the kind a sealed stage throws at you every few hundred metres – the suspension takes the hit at the wheel instead of bleeding it through the shell.

The Tarmac Rally valving is the key to making a long, comparatively heavy saloon usable at pace. It controls the Regal’s rearward weight shift under power-on and keeps the front axle honest under trail-braking, which is where this car traditionally washes wide. Ride height and damping are adjustable on-car, so the same kit covers a fast road set-up and a stage set-up without swapping hardware.

About the Tarmac Rally coilover

The Tarmac Rally is XYZ Racing’s sealed-stage specialist, and the design priorities are different from a circuit coilover. Where a track damper assumes a smooth surface and prioritises platform stability, the Tarmac Rally is valved to absorb the impact of uneven pavement – big single bumps, ripples, expansion joints and broken resurfacing – while still suppressing the shock that would otherwise reach the body. The brief is traction first, then stability.

Every setting in the kit is drawn from XYZ Racing’s own tarmac rally competition experience, which is the part that matters: the valving curves, the rebound behaviour over a crest, the way the damper recovers after a hit. The kit is height adjustable for corner weighting and ride-height fine-tuning, and damping is adjustable so you can match the set-up to surface condition rather than running a single compromise.

The result on a chassis like the Regal is a kit that lets the tyre do its job. The body is held under control, the wheel stays in contact with the road, and the driver feels what the front axle is asking for through the steering rather than guessing at it through body roll.

Fitment for the Buick Regal (2008-2017)

This kit is built for the BU02-chassis Buick Regal, non-GS specification, covering the 2008 to 2017 model years. It is matched to the standard Regal’s spring rates and damper geometry – GS-spec cars use different hardware and are not covered by this part number.
