Description
Subaru ZC6 BRZ (12-21) BC Racing RM coilover kit 6/6 kg/mm
The BC Racing RM coilover kit BRZ ZC6 (part number F-20-RM-MA) is a coilover kit adjustable in height and damping, also simply called a coilover, for the Subaru BRZ (ZC6) with rear-wheel drive, model years 2012 to 2021. The spring rate is 6 kg/mm front and 6 kg/mm rear.
BC Racing lists this RM kit under the Subaru BRZ (ZC6), and it has 6 kg/mm springs front and rear. The RM series is intended for track days, hill climbs and tarmac rally, and on MacPherson struts, such as at the front of the BRZ, it uses an inverted monotube.
The digressive piston gives firm damping at low piston speeds, and the fully synthetic oil with a very high viscosity index changes little in character when the dampers get hot. You set compression and rebound together in 30 clicks.

Fitting and delivery
This RM kit is vehicle-specific for the BRZ ZC6 and replaces the original dampers and springs front and rear. We advise having it fitted by an experienced mechanic and then having the wheel alignment done, also if you use the camber plates. BC Racing advises periodic greasing for the RM and ZR series and recommends them less for road use than the BR, DS, ER or ZX. You receive the kit within 1 to 2 weeks as long as the manufacturer has stock. If BC Racing is temporarily out of stock, you can still order and we will let you know when it is coming.
The BC Racing F-20-RM-MA for the Subaru BRZ ZC6 has 6 kg/mm springs front and rear, an inverted monotube on MacPherson struts and 30 damping settings.
Why choose this RM coilover kit BRZ ZC6?
If you mainly use the BRZ for track days, a hill climb or a tarmac rally, you benefit from suspension that is built for it. The RM delivers that with digressive damping, synthetic oil and camber plates on suitable kits. With 6/6 kg/mm springs, this BRZ version is slightly stiffer than the 5/5 kg/mm of the C-89-RM-MA, which BC Racing UK also lists for the BRZ.

Frequently asked questions
Does the BC Racing RM coilover kit for the BRZ ZC6 also fit the Toyota GT86?
Not according to BC Racing: the C-89-RM-MA with 5/5 kg/mm is intended for the Toyota GT86 (ZN6), and BC Racing UK lists this F-20-RM-MA for the Subaru BRZ (ZC6) with rear-wheel drive, model years 2012 to 2021. BC Racing UK in turn also lists that C-89-RM-MA for the BRZ. If in doubt, contact us.
What is the difference between the BC Racing RM and HM for the Subaru BRZ ZC6?
The HM is 2-way adjustable with an external reservoir; the RM has a single 30-click adjustment for compression and rebound together. The HM combines the inverted design of the RM with the double piston and reservoir of the ER. For the BRZ the RM has 6/6 kg/mm springs and the HM 6/4 kg/mm.
Can I drive the BC Racing RM coilover kit BRZ ZC6 on the road every day?
You can, but BC Racing recommends the RM less for road use than the BR, DS, ER or ZX. The RM coilover kit BRZ ZC6 needs periodic greasing and is aimed at track days, hill climbs and tarmac rally.
