XYZ Racing Drag Racing Coilovers — Fiat BERTONE X1/9 1982-1989

The Bertone X1/9’s transverse mid-engine sits ahead of the rear axle, loading the driven wheels before you have even left the line. The XYZ Racing Drag Racing coilover for the Fiat Bertone X1/9 is built around the 0 to 400 metre job: managing how this light, rear-drive chassis plants its rear contact patches the moment the clutch drops.

This is not a fast-road or circuit setup. The Drag Racing series exists to control weight transfer on the launch and to hold the car steady through the traps, where the X1/9’s short wheelbase and sub-1000kg kerb weight can make it nervous at the top end.

What this coilover does for your 1982-1989 Fiat Bertone X1/9

On a standing-start run the launch-biased valving lets mass shift rearward onto the X1/9’s drive tyres at the instant of launch, pressing them harder into the tarmac so they hook up rather than spin. Less wheelspin off the line means more of the engine’s effort reaches the road and a cleaner sixty-foot time. Because the mid-engined X1/9 carries so little over the front axle, the front is set to allow that transfer instead of fighting it. As speed builds toward the finish, the damping keeps the body settled so the car tracks straight under full power.

About the Drag Racing coilover

The Drag Racing coilover is engineered for one discipline: the 0 to 400 metre run. XYZ developed the platform to suit front-, rear- and four-wheel-drive cars, with settings that deliberately move weight between the front and rear axles in the instant a car launches. The goal is to force greater compression into the driven tyres so they bite rather than break traction, cutting the dead time lost to wheelspin at the start. Once the car is rolling, the same settings work to keep it stable at the high speed reached before the line. On a rear-drive X1/9 the rear holds its line under load while the front stays light enough to let the weight go where it is needed.

Fitment for the Fiat Bertone X1/9 (1982-1989)

This coilover is matched to the Bertone-built Fiat X1/9, chassis code FI03, covering the 1982 to 1989 model years – the late, Bertone-badged version of the car. Confirm your build year falls inside that span before ordering.
