XYZ Racing Tarmac Rally Coilovers — Scion XB bB 2003-2007

The first-generation Scion XB bB carries its mass high. That tall, square body rides on a narrow Toyota NCP-derived chassis that leans early and runs wide the moment you load the nose, which is the one trait a sealed-stage tarmac car cannot live with. The XYZ Racing Tarmac Rally coilover set exists to pin that boxy shell down and put the front tyres back into the road surface.

These are not fast-road dampers softened for comfort. The valving comes from XYZ Racing’s own tarmac rally programme, tuned to soak up the sharp hits of broken and patched stage surfaces while keeping a light, top-heavy car composed through fast changes of direction.

What this coilover does for your 2003-2007 Scion XB bB

Drop the ride height and you immediately cut the bB’s tall centre of gravity, so the body stops toppling onto its outside corner mid-bend. The Tarmac Rally damping is built to absorb a big bump or a kerb strike and settle the shell straight away, rather than letting the suspension pogo and skip the front wheels. That control feeds directly into traction: a tyre that stays loaded puts its power and braking down instead of scrabbling. On a narrow-track car like this, the result is a Scion that turns in flat, holds a line, and stays predictable when the surface turns ugly.

About the Tarmac Rally coilover

This is a damper developed specifically for tarmac rally rather than adapted from a road kit. It is engineered to absorb the impact of uneven, broken pavement and to suppress the shock transmitted into the bodyshell when the car crosses heavy bumps and compressions at speed. By keeping the wheel in contact and the chassis settled, it increases the available traction at the contact patch and holds the car stable through quick transitions. Every setting in the kit is drawn from XYZ Racing’s accumulated tarmac rally competition experience, so the baseline is a working stage tune, not a guess.
