XYZ Racing Circuit Master Coilovers — Honda PRELUDE BA4/5/7 1987-1991

The third-gen Prelude is a chassis that rewards a driver who actually commits to the corner – double-wishbones at all four corners, optional four-wheel steering on the BA5, and a kerb weight that flatters every increment of damper control you give it. The Circuit Master is the spec in the XYZ range built to exploit exactly that, and it is the kit you fit when you have stopped caring about the school run and started caring about your sector times.

For sustained circuit work in a BA4, BA5 or BA7 Prelude, this is the right rung of the XYZ ladder. The double-wishbone geometry responds beautifully to proper rebound control, and the Circuit Master is built around the assumption that you will be using every bit of it.

What this coilover does for your 1987-1991 Honda Prelude

Drop a Circuit Master onto a third-gen Prelude and the first thing you feel is composure mid-corner – the loose, slightly bobbing rear that stock dampers develop after thirty-odd years of service is gone, replaced by a platform that takes a set and stays there. The 9720 distinct adjustment combinations across the three knobs mean you can run a soft compression setting for kerb-hopping at a circuit like Cadwell, then close the rebound back up for a flat-and-fast venue like Snetterton on the same weekend. Turn-in sharpens noticeably, because you are finally giving the front wishbones a stable platform to work against rather than asking tired OE struts to manage everything. Braking stability into a downhill, off-camber entry – the kind of corner the Prelude’s long bonnet historically struggles with – improves once you have proper bump control under the nose. And because ride height is independently adjustable from spring preload, you can corner-weight the car properly without compromising the geometry the BA chassis was designed around.

About the Circuit Master coilover

The Circuit Master is XYZ’s competition-spec damper, sitting in the same tier as their Racing Spec, Drift Spec and Tarmac Rally kits. It has been developed and validated by XYZ race teams on circuits around the world, which is where the three-knob architecture comes from – separate adjusters for low-speed compression, high-speed compression and rebound, giving you the full 9720-way matrix to map damping to a specific venue and tyre. The damper bodies use a small-orifice oil passage that delivers the sharp, direct feel a circuit driver wants under load; the trade-off is a faint hydraulic note over very large bumps, which is normal and expected for this construction and not something you will notice on a smooth racing surface. Ride height and damping are independently adjustable, so spring preload is never being used to set ride height. This is a kit designed specifically for circuit tracks, and it is the spec XYZ teams have used to take outright wins.

Fitment for the Honda Prelude (1987-1991)

This kit is built for the third-generation Honda Prelude, chassis code HN44, covering the BA4, BA5 and BA7 variants produced from 1987 through 1991. The platform shares its double-wishbone front and rear architecture across all three variants, and the coilover spec is matched to that chassis family.
