XYZ Racing Tarmac Rally Coilovers — Lexus RC F (USC10) (Modified Rear Integrated) (Front EYE) 2015-2018

The RC F’s naturally aspirated 5.0-litre V8 sends over 470bhp through a chassis that was never built with sealed-stage rally in mind, and that’s exactly the gap this Tarmac Rally coilover is built to close. Where a road or track coilover chases lap time on smooth, known surfaces, this set is tuned for the opposite problem: broken tarmac, crested compressions and mid-corner ruts you can’t see coming twice.

On a car this heavy through the nose, absorbing a hard hit without unsettling the rear axle matters more than outright stiffness. This is the USC10-specific application, built around the RC F’s Modified Rr Integrated rear geometry and Frt EYE front mounting, so the damper is sized to this chassis rather than adapted from a shared platform.

What this coilover does for your 2015-2018 Lexus RC F

Fitted to the RC F, the Tarmac Rally kit changes how the car deals with the surface underneath it rather than just how it sits. Big compressions, whether that’s a mid-stage jump landing or a UK B-road pothole taken at speed, get absorbed instead of transmitted straight into the chassis, which keeps the body settled when you’d otherwise get a kick through the wheel. That control translates directly into tyre contact: less vertical bounce off a bump means the contact patch stays loaded and traction holds through the moment that matters. On a naturally-aspirated V8 car carrying real weight over the front axle, that stability under compression also protects the balance you’ve dialled into the rest of the chassis, so the RC F stays predictable when the road stops being smooth. Ride height and corner-weighting adjustment let you correct for the car’s nose-heavy stance before you even get to a stage.

About the Tarmac Rally coilover

XYZ Racing developed the Tarmac Rally damper specifically to soak up the kind of punishment a sealed-stage road throws at a car that a circuit never will: broken surfaces, big elevation changes and the sort of jolt you get from launching off a crest. The valving is set to absorb that impact rather than fight it, controlling body movement through the hit so the chassis doesn’t skip or step sideways when the suspension compresses hard. That control is also what keeps the tyre working – suppressing body movement stops the contact patch unloading, which is where traction actually gets lost on a rough stage. XYZ Racing built the settings on this damper from its own tarmac rally programme, carrying over the compression and rebound targets that keep a car planted and predictable when the driver can’t see what’s coming next. It’s a construction aimed squarely at stability under repeated hard impacts rather than outright low-speed compliance.

Fitment for the Lexus RC F (2015-2018)

This kit is built for the USC10-chassis RC F, model years 2015 to 2018, specifically for cars running the Modified Rr Integrated rear suspension configuration paired with the Frt EYE front mount. Confirm your RC F matches this rear integration spec before ordering, as it determines which coilover variant is correct for your car.
