XYZ Racing Top Sport Coilovers — Scion XB bB 2003-2007

The first-generation Scion XB bB carries its mass high. That upright, van-like roofline sits a long way above the axle line, and the soft factory springs let the body lean and pitch well before the front tyres are doing any real work. The XYZ Racing Top Sport coilover exists to bring that motion back under control on a light front-drive platform that never had much damping authority to start with.

This is the kit for an owner who runs the bB on the road most weeks and takes it onto a circuit now and then. It drops the centre of gravity, firms the chassis enough to load the front tyres cleanly, and keeps the ride composed enough to commute on.

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

The first thing you feel in a 2003-2007 Scion XB bB after fitting is how flat the tall body stays through a roundabout or a quick lane change. The shell stops heaving, and the steering starts to feel tied to the front axle instead of arriving a beat late. XYZ runs the Top Sport roughly 30 to 50 percent firmer in damping, or up to 2kg/mm stiffer in spring rate, than a street tune – and on a car this light, that extra control is what presses the contact patch down and sharpens turn-in. Height adjustment lets you set a stance that still clears UK speed bumps while pulling the wheel up into the arch.

About the Top Sport coilover

The Top Sport is drawn straight from XYZ Racing’s own Top Sport development work. Running 30 to 50 percent more damping or around 2kg/mm more spring rate than a road setting, it has the reserve to swallow a sharp hit over broken tarmac and settle the body quickly after a big bump, rather than letting the suspension crash through its travel. By suppressing that body shock the damper keeps the tyre planted, which is where the gain in traction and stability comes from. It is built for track-day running and harder driving while staying usable enough for daily street use, so you are not choosing between a circuit setup and a car you can live with.
