Description
BMW F87 M2 non-Competition (16-18) BC Racing ZX coilover kit 6/12 kg/mm
The BC Racing ZX coilover kit M2 F87 (part number I-75-ZX) is a coilover kit adjustable in height and damping, also simply called a coilover, for the BMW M2 F87, model years 2016 to 2018 (not the M2 Competition). The spring rate is 6 kg/mm front and 12 kg/mm rear.
The ZX series combines the BC Racing DS and ER into a 3-way coilover kit for competitive track use, long sessions and demanding drifting. The upright monotube dampers have a dual piston, an external reservoir and racing oil with a very high viscosity index.
You adjust three things separately: 20 clicks of compression at low speed, 12 clicks of compression at high speed and 30 clicks of rebound. For the M2 F87 the kit comes with 6 kg/mm springs front and 12 kg/mm rear, and the upper mounting is replaceable.

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 step by step on track. The delivery time is 1 to 2 weeks as long as the manufacturer has stock. If BC Racing temporarily does not have the ZX kit in stock, you can still order and we will tell you the expected delivery date.
The BC Racing I-75-ZX is a 3-way coilover kit for the BMW M2 F87 with 20 clicks of low speed compression, 12 clicks of high speed compression and 30 clicks of rebound.
Why choose this ZX coilover kit M2 F87?
If you race the M2 F87, do long sessions or serious drifting, the ZX gives you one extra adjustment compared with the ER: the compression is split into low and high speed. This lets you tune separately how the car reacts to slow body movements and to sharp impacts from kerbs. Because the dampers are rebuildable, you can have them rebuilt after a season.
