XYZ Racing Drag Racing Coilovers — Mazda COSMO 13B/20B ROTARY 1990-1996

The Eunos Cosmo was never built to be quick off a line. It was a 1,600kg-plus grand tourer carrying the only triple-rotor engine Mazda ever sold, the 20B-REW, with the twin-rotor 13B-RE underneath it – a heavy, rear-drive luxury platform that puts its mass over a long wheelbase and asks a lot of its rear tyres the moment you load them. That weight is the problem and the opportunity. Manage where it goes under launch and the Cosmo can hook up hard; leave it to the soft factory dampers and you spin, squat, and waste the boost.

This XYZ Racing Drag Racing coilover set for the 1990-1996 Mazda Cosmo 13B/20B Rotary is built for exactly that job: turning a heavy GT chassis into something that plants its drive wheels on a quarter-mile run rather than lighting them up.

What this coilover kit does for your 1990-1996 Mazda Cosmo 13B/20B Rotary

The setup is tuned to control weight transfer between the front and rear axle as you launch, so the rear tyres take a sharper vertical load the instant you drop the clutch or sidestep the line. On a rear-drive Cosmo that means less wheelspin off the start and a cleaner hand-off as the sequential turbos come up. The damping and rate balance shorten the time the driven wheels spend slipping, which is where seconds disappear on a 0-400 metre pass. Down the strip, the same firmer platform keeps a tall, heavy car settled at the top end of third and fourth, where a soft chassis would wander.

About the Drag Racing coilover

This is XYZ Racing’s dedicated 0-400 metre coilover, designed for straight-line work across FWD, RWD and 4WD applications and configured here for the rear-drive Cosmo. The geometry is set up to shift front and rear weight toward the driven axle during the launch, forcing greater compression into the drive tyres so they bite instead of spinning. Reducing that idle, slipping moment is the whole point: the kit trades the road-biased compliance of the original suspension for a platform that loads the contact patch predictably and holds the car stable as speed climbs. It is a focused tool for drag use with high launch loads, not a fast-road compromise.
