XYZ Racing Super Sport Coilovers — BYD F0 2008-2026

The Byd F0 sits at the awkward end of the modification spectrum – a sub-tonne city car on a short wheelbase that turns into a pogo stick the moment the road surface deteriorates or you ask it to corner at speed. Standard damping was specified for low-speed urban work, not for the spring rates and reduced ride height that owners running enthusiast setups actually want. The XYZ Racing Super Sport coilover targets exactly that gap.

For a fast-road F0 that still does the school run during the week and visits a circuit on a Sunday, 36-way damping and full ride-height adjustment give you the range to set the car up properly for both jobs without swapping parts. The Super Sport is the type in the XYZ catalogue aimed at weekend track use without giving up daily driveability.

What this coilover does for your 2008-2026 Byd F0

Drop the front of an F0 by 25-35mm and the steering immediately feels less remote – weight transfer settles faster, turn-in stops feeling like you’re asking permission. The 36 damping clicks are the working tool here: soften the rebound for British B-road camber changes mid-week, then wind it stiffer on Saturday morning before a track session and the car stops floating over kerbs. Ride-height adjustment is independent at each corner, so corner-weighting and rake are both on the table. Because the damper construction is built for repeat heat cycles rather than just for the static spec sheet, the kit holds its behaviour through a 20-minute session rather than going off after three laps.

About the Super Sport coilover

The Super Sport is XYZ Racing’s dual-purpose damper – aimed at owners who want a genuine track-capable setup that still works on the road on Monday. It runs 36-way bump-and-rebound adjustment from a single knob per damper, giving a usable spread between a compliant fast-road setting and a tied-down circuit setup. Ride height is fully adjustable via the lower mount, which keeps the shock stroke independent of how low you run the car – important on a short-travel chassis like the F0 where preload-based "coilovers" run out of bump travel almost immediately. The damper internals are tuned to absorb the bumps and broken surfaces that would otherwise turn a stiffened car into a jackhammer, which is what the type is engineered around: a high-performance damper that doesn’t punish you when the road turns rough. It is built to be set up once for the way you actually use the car, and left there.
