XYZ Racing Tarmac Rally Coilovers — Toyota MARK X GRX120 2004-2009

The GRX120 Mark X left Toyota as a comfort-biased rear-drive saloon, riding on long-travel springs and soft damping built for smooth commuting rather than committed driving. That setup floats and rolls the moment you ask it to carry speed across a broken sealed surface, and the rear axle goes light over crests exactly when you need it planted. The XYZ Racing Tarmac Rally coilover for the Toyota MARK X GRX120 is tuned to take that float out without turning the car into something unusable on a patched, undulating stage road.

This is a rally damper, not a stiff circuit kit pressed into service on a saloon. Tarmac Rally tuning prioritises wheel control and compliance over raw stiffness, so the GRX120 keeps soaking up impacts while the body stays settled and the rear-drive chassis stays readable through fast direction changes.

What this coilover does for your 2004-2009 Toyota MARK X GRX120

After fitting, the first thing you feel is that the nose stops diving and the body stops wallowing through quick transitions, which makes the 2.5 V6 GRX120 far easier to place on a rough stage. The damping is built to absorb big bumps and jolts rather than skip across them, so the tyres stay loaded and traction holds where the standard car would have unsettled itself. You get adjustable ride height to set the stance and corner balance you want, and a more linear weight transfer that lets you trust the rear axle on power. On a fast-road run, the same compliance means it copes with Britain’s broken back lanes instead of fighting them.

About the Tarmac Rally coilover

The Tarmac Rally coilover is engineered specifically for sealed-stage rally use, where the road surface is uneven, patched and frequently scarred. Its valving is set to absorb the impact of rough pavement and damp out the heavy jolt that comes from hitting a large bump at speed, instead of passing that shock straight into the bodyshell. By suppressing that shock and keeping the wheel in contact with the ground, the damper increases tyre traction and gives the car the stability that lets you commit through a corner with confidence. The handling it delivers comes from XYZ Racing’s own tarmac rally programme, with the base settings drawn directly from that competition experience rather than a generic road tune. For the GRX120, that means a setup that respects the platform’s long-travel character while removing the slack that holds it back.
