Toyota A90 GR Supra (19+) BC Racing ZX coilover kit 18/8 kg/mm

The BC Racing ZX coilover kit Supra A90 (part number C-165-ZX) is a coilover kit adjustable in height and damping, also simply called a coilover, for the rear-wheel drive Toyota GR Supra (A90), from model year 2019. The spring rate is 18 kg/mm front and 8 kg/mm rear.

The ZX series combines the DS and the ER from BC Racing in a 3-way adjustable coilover kit. You set low-speed compression (20 clicks), high-speed compression (12 clicks) and rebound (30 clicks) separately, on upright monotube dampers with a double piston and an external reservoir.

BC Racing builds the ZX for competitive track use, long sessions and demanding drifting. What stands out in the A90 kit is the spring distribution: the front spring is much stiffer than the rear, whereas the BR, DS, RM and ER for the A90 have the stiffer spring at the rear.
