Honda Civic Type R FK2

Coilover suspension kit

Honda’s 4th generation Civic Type R is the first front wheel drive production road car to lap the Nurburgring in 7 minutes and 50 seconds and the first Type R to be factory turbo charged. TGM Sport of Fleet in Hampshire chose Quantum to provide the suspension for their Civic, built to compete in the 24H Touring Car Endurance Series.

The kit features a 40mm MacPherson strut up front and an adjustable Zero monotube at the rear. Camber adjustable top mounts are just part of a solution we engineered that increases camber at the front wheels by more than 1-1/2 degrees.

The steel MacPherson strut cases have been treated to a Xylan coating. This anti-corrosion finish has low-friction and non-stick properties, minimising the risk of dirt adhering to the screw-cut threads. A needle roller thrust bearing also makes adjustment of the coil spring easier and eliminates friction in the assembly.

Two-way adjustment of the strut damping is achieved using a bump canister—a worthwhile compromise that sacrifices a little adjustability for ease-of-use in this application. Compression adjustment is handled by the can and rebound adjustment is made at the base of the strut.

Damping at the rear is managed by a pair of Two.Zero shock absorbers. A billet aluminium clevis bolts into the stock location and provides a hard mount where previously there was a compliant bush. The two colour-coded damping adjusters are easily accessible down near the trailing arm: Black for bump and red for rebound.

The road spring remains in its stock location but adjustment has been made possible using an articulated spring seat. We provided TGM a pair of threaded bushes to weld into the stock trailing arms that allow preload to be adjusted from beneath the car using a 6 point socket. A large spherical bearing inside the spring perch accounts for misalignment as the suspension moves through its range of motion.
