XYZ Racing Tarmac Rally Coilovers — Chrysler 300C 4WD 2005-2010

The Chrysler 300C 4WD carries close to two tonnes over the LX platform’s long wheelbase, and on a broken tarmac stage that mass wants to keep travelling in a straight line long after the road has turned. XYZ Racing’s Tarmac Rally coilover is built around that problem: a damper calibrated to soak up the compression spikes thrown up by cambered apexes, patched farm roads and mid-corner ruts, rather than letting the body pitch and roll away from the driver.

For a crew campaigning a 2005-2010 300C 4WD on closed tarmac stages, that means the front and rear axles stay planted through the transition from smooth asphalt to broken surface without the car skating wide or the driver having to back off to protect the chassis. It is set up for sealed-stage tarmac rally use, where surface changes happen mid-corner and there is no second run to get the line right.

What this coilover does for your 2005-2010 Chrysler 300C 4WD

Fitted to the 300C 4WD, this coilover keeps the big saloon’s mass under control when the road surface turns rough mid-stage. The damper absorbs the jolt from large hits rather than transmitting it straight into the body, which keeps the tyre in contact with the road and holding traction instead of skipping over the top of an impact. That matters on a 4WD platform sending power through all four corners: traction lost to a bouncing wheel is traction the drivetrain cannot use. The result on the road is a car that settles faster after a compression, turns in with less lean, and lets the driver commit to a line on a surface that is not consistently smooth from apex to apex. Ride height and corner balance are adjustable, so the 300C 4WD can be set up level and to the stage-specific stance a rally crew needs rather than whatever the factory spring rate happened to produce.

About the Tarmac Rally coilover

The Tarmac Rally coilover is XYZ Racing’s damper for sealed-stage work on broken, uneven asphalt rather than a smooth circuit surface. Internally it is tuned to absorb impact from rough pavement and large bumps without transferring that shock straight into the chassis, which is what keeps the tyre loaded and gripping through a hit instead of skipping. That control is what XYZ describes as stability that lets a crew experience proper handling through a stage rather than fighting the car after every compression. The valving and spring settings supplied with this kit come directly from XYZ Racing’s own tarmac rally programme, carried over rather than generalised from a road-car base tune. It is built for the specific demands of stage driving: repeated hard hits, fast direction changes, and a surface that rarely stays consistent for more than a few metres.

Fitment for the Chrysler 300C 4WD (2005-2010)

This kit is built for the Chrysler 300C 4WD, chassis code CR01-1, covering the 2005 to 2010 model years. Confirm your car is the 4WD variant of the LX-platform 300C before ordering, as the driven-axle geometry differs from the rear-wheel-drive version.
