About ZR Series
BC Racing's new ZR Series Coilovers bring a 3-way adjustable track ready coilover system to racers from novice to pro for a price not seen before in the performance suspension market. Each ZR Series Coilover system offers independent low speed and high speed compression adjustment and separate rebound adjustment. They also offer full height adjustability independent of piston travel and spring preload.
On cars with McPherson struts the ZR Series comes standard with an inverted monotube damper with the steel braided Teflon coated line exiting the top of the damper to the external reservoirs that can be remotely mounted in the engine bay or boot. The ZR Series kits offer 30 clicks of rebound adjustment, 15 clicks of low speed compression adjustment, and 12 clicks of high speed compression.
Pillowball (rose joint) upper mount
Many of the BC Racing ZR coilovers come with pillowball upper mounts. The mount itself is made from aluminium alloy, anodised and then bead blasted to give a high quality, durable finish.
The pillowballs themselves are of Japanese manufacture and their solid nature eliminates any flex or play associated with the standard rubber mounts so improving response and handling.
Nitrogen pressurised dampers
When you work a damper hard on track or on high speed bumpy roads you can cause the oil to aerate and cavitation can occour. This causes foaming which effectively reduces the oils viscosity and so reduces the units damping effect. High quality oil goes a long way to help reduce this problem but BC Racing go one step further and pressurise the dampers with nitrogen.
The nitrogen exerts a pressure on a floating piston which in turn exerts a permanent pressure on the oil dramatically reducing aeration and so improving the consistency and quality of the damping. The pressurised nitrogen also adds an additional element of effective spring rate to the damper unit.
