XYZ Racing Circuit Master Coilovers — Honda INTEGRA DA6 SINGLE CAM (Rear FORK) 1989-1993

The DA6 Integra sits in an odd spot for a chassis you want to take seriously on a circuit: a light, revvy single-cam front-driver from the back end of the 1980s, with a rear-fork suspension layout that pre-dates the double-wishbone DC2 by half a generation. Owners keeping these cars sharp in 2026 are wrestling with worn factory dampers, sagging springs, and a chassis that wants to push wide on entry long before the front tyre is actually finished. The Circuit Master is the answer for drivers who have moved past fast-road compromises and want a coilover built specifically for repeat lap work.

This is the kit you fit when track days have stopped being occasional and started being the point. It is engineered around sustained heat, repeat compression cycles, and the kind of damping authority a 1989-1993 Integra was never going to see from the showroom floor.

What this coilover does for your 1989-1993 Honda Integra

Body control is where you will feel it first. The Circuit Master pins the DA6 down on turn-in, killing the float that worn OE struts let through over kerbs and crests, so the nose actually goes where you point it instead of arguing the line halfway through the corner. With 9720 distinct adjustment combinations across the three knobs, you can run a softer compression setting for bumpy UK circuits like Cadwell or Donington’s chicane, then close it up for smoother tarmac at Silverstone or Bedford. Front-end grip under trail-braking improves sharply, which is the single biggest gain a light front-driver like the DA6 can extract from a proper damper. Mid-corner you get a stable platform that lets the inside-rear lift cleanly rather than scrabbling, and on exit the car settles fast enough to put the power down out of slower corners without a second steering input.

About the Circuit Master coilover

The Circuit Master is XYZ Racing’s competition-tier damper, shared in design philosophy with their Racing Spec, Drift Spec, and Tarmac Rally builds. It runs three separate adjustment knobs covering 9720 individual damping permutations, and it has been developed and validated by XYZ racing teams running it on international circuits over long test programmes. Construction is built around the demands of pure circuit use rather than road compliance, which means the internal oil passages are sized for sustained, hard work – owners should expect a small amount of valve noise over large road bumps as oil moves through the smaller competition passages, which is normal and intentional for this spec. This is unapologetically a circuit damper. Fit it to a car that lives on smooth tarmac and gets driven hard at weekends, not one that needs to commute over speed-humps every morning.

Fitment for the Honda Integra (1989-1993)

This kit is built specifically for the DA6 chassis with the single-cam engine and the rear-fork suspension layout, covering the 1989-1993 model years. Chassis code AC05 applies. If your car is the later DA6/DA8 double-wishbone variant or a DB-series Integra, this is not the correct kit – confirm your rear suspension layout before ordering.
