BC Racing BR Series Coilovers for BMW Z4 M E85 06-08

BC Racing BR Series coilovers feature 30 way damping adjustment that combines both rebound and compression in one adjuster for simplicity and ease of use. This adjustable facility allows you to fine tune the vehicle to meet the relevant conditions.  The dampers are also nitrogen pressurised to reduce oil cavitation.

Ride height is determined by the position of the coilover bottom mount. The mount can be wound up and down the damper body to give a full range of adjustment.  Because ride height is determined by an adjustable bottom mount rather than the spring platform itself, you retain full damper travel regardless of the ride height run.

BR series coilovers use a large 46mm diameter piston in a 53mm diameter damper body to maximise oil capacity.  On suspension dampers, as the unit operates the oil contained within it heats up. The viscosity of oil changes as its temperature varies which can lead to changes in the damping characteristics of the unit.  BC Racing only use a very high quality oil with their coilovers.  This combined with the large 53mm diameter damper body, which allows for a greater volume of oil within the damper, reduces the peak temperature and significantly improves damper performance.

BC Racing coilovers only use the highest quality steel for their spring manufacturer. They are produced from SAE9254 high strength durable cold wound steel.  The springs are compression tested through over 500,000 cycles with less that 5% deformation.

This kit comes with the standard spring rate that is recommended by BC Racing as the best balance of performance and comfort.  It is very capable for fast road and track work but also retains a high degree ride civility for normal road use.
