Description
BC Racing ZX coilover kit BMW M2 Competition F87 (18-21) 6/12 kg/mm
The BC Racing ZX coilover kit M2 Competition (part number I-98-ZX) is a coilover kit adjustable in height and damping, also simply called a coilover, for the BMW M2 Competition F87, model years 2018 to 2021. The spring rate is 6 kg/mm front and 12 kg/mm rear.
With the ZX series, BC Racing brings the DS and the ER together in a 3-way coilover kit for competitive track use, long sessions and demanding drifting. The M2 Competition has its own ZX kit, with springs of 6 kg/mm front and 12 kg/mm rear.
The upright monotube dampers have a twin piston and an external reservoir, work digressively and are filled with racing oil with a very high viscosity index. You adjust the low-speed compression in 20 clicks, the high-speed compression in 12 clicks and the rebound in 30 clicks.

Fitting and delivery
The kit is vehicle-specific and replaces the original dampers and springs. We recommend having it fitted by an experienced mechanic. Have the wheel alignment set after fitting, and then tune the three damping settings one by one. The delivery time is 1 to 2 weeks as long as the manufacturer has stock. If BC Racing temporarily has the ZX kit out of stock, you can still order and we will let you know when it comes in.
For the BMW M2 Competition F87, BC Racing supplies the 3-way ZX coilover kit I-98-ZX, with external reservoir, racing oil and springs of 6/12 kg/mm.
Why choose this ZX coilover kit M2 Competition?
The ZX is intended for anyone who races the M2 Competition, does long sessions or drifts seriously. Because low-speed and high-speed compression are adjustable separately, you tune the response to slow body movements and to sharp impacts independently of each other. The dampers are rebuildable, so after a season you can have them rebuilt.
