XYZ Racing Super Sport Coilovers — Opel KADETT C 1973-1979

Almost five decades after the last Kadett C left Rüsselsheim, the OP04 platform remains genuinely active: in historic rally classes, at classic-car track days, and with owners who simply want to drive a sub-900 kg rear-wheel-drive car the way it deserves. The factory spring and damper package was adequate for 1970s European roads but leaves little room for adjustment – a limitation that registers immediately on a chassis where short wheelbase and light weight make every suspension change feel significant.

The Super Sport is XYZ Racing’s coilover for fast-road and weekend track use, and that brief aligns directly with how most OP04-chassis Kadetts are driven today: long enough on the road to need compliance, but sharp enough on a circuit or stage to demand something better than stock.

What this coilover does for your 1973-1979 Opel KADETT C

The Super Sport’s 36-way damping range covers the full spread of what a Kadett C owner actually needs. Softer settings handle the broken tarmac of heritage rally routes and UK B-roads without beating up the car or its occupants; firmer settings keep the rigid rear axle controlled under hard acceleration – which matters particularly in the GT/E, where the 1.9-litre CIH engine puts real demands on what the chassis can manage. Ride height is fully adjustable, letting you clean up the Kadett’s stance without pushing the centre of gravity higher than its short wheelbase can comfortably accommodate.

About the Super Sport coilover

XYZ Racing positions the Super Sport between pure road comfort and dedicated track hardware – a damper that addresses rough-road harshness as a named design goal rather than a secondary consideration. The 36-way adjustment is the mechanism that delivers this range, spanning from compliant fast-road settings to firm weekend-race configurations without requiring a component swap between uses. Ride height adjustment is included as standard, giving owners direct control over stance and static geometry. Validated for both daily driving and weekend racing, the Super Sport makes sense for Kadett C owners whose use cycle rarely fits a single category – one setting for the road, a firmer step for the stage or circuit, all within the same kit.
