XYZ Racing Tarmac Rally Coilovers — Hyundai GENESIS COUPE BK 3.8 (Modified Rear Integrated) 2008-2010

The Genesis Coupe BK’s 3.8 V6 puts a genuine 300kg-plus over the front axle, and on the loose, cambered surfaces of a tarmac stage that weight transfer arrives fast and unforgiving. Stock dampers weren’t specified for the compression spikes a rough stage throws up crest after crest – they were tuned for a smooth road surface, not a rally special stage with mid-corner ruts and camber changes.

XYZ Racing’s Tarmac Rally coilover is built for exactly that environment. It’s the spec for a Genesis Coupe BK owner running competitive tarmac rally rather than lapping a circuit, where the demands on a damper are completely different from track work.

What this coilover does for your 2008-2010 Hyundai Genesis Coupe BK

Fitted to the BK chassis, this kit is set up to absorb the impact of an uneven stage surface rather than transmitting it straight into the chassis. Where a big compression event would normally kick the body and unsettle the rear-drive platform mid-corner, the damper is tuned to suppress that shock and keep the tyre loaded against the road instead of skipping off it. That translates directly into traction – on a car putting V6 torque down through the rear axle, keeping the contact patch planted through a bump is what actually determines whether you carry speed out of a stage corner or lift and correct. The result on the Genesis Coupe is a car that holds its line over broken surfaces where a standard setup would have you fighting the wheel.

About the Tarmac Rally coilover

This is a damper built specifically around the loads of sealed-stage tarmac rally, not a road coilover with a rally badge on it. XYZ Racing developed the valving using data from its own rally programme, so the compression and rebound settings reflect what actually happens on a stage rather than a generic track calibration. The core job of the damper is absorbing the jolt from big, sudden bumps – crests, ruts, camber changes – without letting that energy travel into body movement that unsettles the car. Suppressing that shock is what keeps the tyre’s contact patch consistent and stops the car from stepping sideways when a compression hits mid-corner. All of the settings on this kit come from that Tarmac Rally racing experience, aimed at giving the driver predictable, stable handling stage after stage rather than a soft ride for the commute.

Fitment for the Hyundai GENESIS COUPE BK 3.8 (Modified Rr Integrated) (2008-2010)

This kit is built for chassis code HY09-1, covering the Hyundai Genesis Coupe BK with the 3.8 V6 across the 2008-2010 production run, in the modified rear-integrated configuration. Confirm your car matches the 3.8 V6 variant and this year range before ordering, as the Genesis Coupe’s 2.0T and 3.8 platforms use different suspension geometry.
