XYZ Racing Super Sport Coilovers — Scion XB bB 4WD 2003-2007

The Scion XB bB’s tall, boxy body carries its weight high off the road, and the 4WD hardware bolted underneath adds mass over the rear axle that the factory dampers were never set up to control. Push one into a fast corner and that height shows up as body roll the wagon’s stubby footprint doesn’t hint at from the outside, while the extra driveline weight changes how the rear settles under load compared with the front-wheel-drive version of the same car.

The XYZ Racing Super Sport coilover kit for the XB bB 4WD is built around that reality: a coilover set that drops the centre of gravity and gives the driver a damper they can set up for a Saturday track session and drive home on afterwards. It’s the fast-road and weekend-track spec in the range, not a full race-only setup, so it’s built to live with speed bumps and motorway miles as much as apex kerbs.

What this coilover kit does for your 2003-2007 Scion XB Bb 4WD

Dropping the ride height on the XB bB 4WD lowers the roll centre and cuts into the body lean that comes with the car’s tall proportions, so the chassis changes direction with less of the top-heavy wallow the factory setup allows. The 36-way damping adjustment means the front and rear can be set stiffer for a track session, where controlling that extra 4WD mass under braking and turn-in matters most, then backed off for a comfortable daily commute without swapping parts. Independent ride height adjustment also lets you correct the nose-down or tail-low stance the added driveline weight can leave the XB bB with from the factory, levelling the car visually and dynamically at the same time. None of this needs a full respring to feel different from the stock setup – the adjustment range is built into the damper itself.

About the Super Sport coilover

The Super Sport coilover is XYZ Racing’s answer to a suspension that’s been livable enough for daily roads and firm enough for a fast lap. The 36-way damping adjustment covers a wide enough range to go from a comfortable commuting setting to a stiffer track-day tune without changing components, and the threaded body means ride height is adjustable independently of spring preload. It’s built to soften the harshness that stiffer aftermarket suspension usually introduces on rough tarmac and speed humps, rather than trading comfort away entirely for lap time. That range is the point of the Super Sport line: one coilover kit doing weekend racing and daily driving duty on the same car, rather than forcing a choice between the two.

Fitment for the Scion XB Bb 4WD (2003-2007)

This kit is specced for the SC04 chassis Scion XB bB 4WD built between 2003 and 2007. Confirm your XB or bB is the 4WD variant before ordering, since the driveline layout changes the rear suspension geometry the coilover is designed around compared with the front-wheel-drive car.
