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

The DA6 Integra’s fork-type rear suspension is the detail that defines this car’s behaviour on a circuit: the rear knuckle clamps onto the damper body, so any flex, any imprecision, any cheap rebound valving gets fed straight into the contact patch under load. Get the rear damping right on a DA6 and the B16A’s 8,000rpm top-end finally has a chassis that can use it. Get it wrong and the car skates wide on corner exit while you’re still hunting the next gear.

That is the brief the XYZ Racing Circuit Master coilover is built for. This is the top-tier circuit-spec damper in the XYZ range – three separate adjustment knobs feeding a 9,720-position adjustment matrix, developed and signed off by XYZ’s own racing teams on international circuits before it ever reached a customer car.

What this coilover does for your 1989-1993 Honda Integra DA6

On a DA6 set up for sustained lap work, the Circuit Master gives you something the standard car has never had: separate control over low-speed body movement and high-speed bump response. You can stiffen the platform for kerb-strikes at Cadwell or Brands without making the car skittish over the patched tarmac on the way home. The three adjusters let you tune compression and rebound independently, so the front end stops diving under threshold braking into a hairpin while the rear stays planted on power-on rotation out of it. With the rear fork mounting, the precision of the damper body matters more than on a conventional rear strut – this is where a circuit-grade unit pays back across a full session as the oil heats up and cheaper dampers start to fade.

About the Circuit Master coilover

The Circuit Master sits at the top of the XYZ Racing range alongside the Racing Spec, Drift Spec and Tarmac Rally builds – the company’s competition-grade tier rather than its fast-road one. Construction centres on a three-knob adjuster cluster that opens up 9,720 distinct damping permutations, designed so a driver can isolate a single corner’s behaviour without unwinding the rest of the setup. XYZ developed the damper through a long validation programme with their own race teams on international tracks. One quirk worth knowing: the small-orifice valving inside the adjusters can produce a faint audible note when the car hits a sharp edge or a deep bump at low speed. It is a function of the precision passages, not a fault, and it is the trade-off for the resolution of adjustment the damper delivers on smooth circuit surfaces. This is a damper built for tarmac with a known surface, not for unsurfaced rally stages or broken back-road work.

Fitment for the Honda Integra DA6 TWIN CAM Rr Fork (1989-1993)

Direct fitment for the DA6 chassis code Integra Twin Cam with the rear fork-type suspension, 1989 to 1993 model years. Confirm your rear lower mounting is the fork style (not the later eye-mount layout) before ordering – the bracket geometry is specific to this generation.
