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

The DA6 Integra’s rear fork suspension is the geometry that defines how this chassis behaves on a B-road and on circuit – independent at the front, with a unique rear arrangement that rewards a properly matched damper far more than it rewards raw spring rate. The Top Sport coilover for the AC05 Integra is built around that reality: a setting roughly 30-50% firmer in damping than a street kit, with spring rates around 2kg/mm above standard, so the car still works on UK roads but stops running out of damper control when you load it up.

For an early-90s Honda whose 1.6 single-cam shell weighs comfortably under a tonne, this is the coilover spec that makes the chassis come alive without ruining the weekday commute. Owners running these cars in 2026 are usually balancing scarcity against use – and the Top Sport sits where most of them actually want to be.

What this coilover does for your 1989-1993 Honda Integra DA6 Single CAM (rr Fork)

The firmer damping curve suppresses the body float that 30-plus-year-old factory dampers can no longer control, so the nose stops diving into trail-braking and the rear stops skipping over mid-corner bumps. Stepping spring rates up by around 2kg/mm sharpens turn-in without making the car nervous over the kind of broken Tarmac you find on a typical UK B-road. The kit is designed to absorb the impact of uneven pavement and the jolt of larger bumps rather than just stiffening everything until the tyres lose contact – which matters on a light chassis where keeping the contact patch loaded is the whole game. Tyre traction improves because the damper is actually doing its job, and the car settles between corners instead of bouncing into the next one. The result is a DA6 that feels planted rather than busy, with a ride that holds up to spirited driving without becoming a chore on the way home.

About the Top Sport coilover

The Top Sport sits in XYZ Racing’s range as the spec for occasional track day use combined with daily-driveable street manners. Damping is set roughly 30 to 50 percent firmer than the street-only kit, with spring rates approximately 2kg/mm above standard – enough to suppress shock through the body shell, control wheel movement over larger bumps, and keep the tyre loaded through compressions, without crossing into a stripped-out circuit-only build. Every setting in the kit is derived from XYZ Racing’s Top Sport racing programme, which is where the damping curves and rate pairings come from rather than a generic catalogue spec. It is built specifically for track day use and aggressive driving, and the bias of the whole kit is toward stability under load so the chassis stays predictable when you start asking real questions of it.
