Description

BC Racing RM coilover kit Toyota GR Supra A90 (19+) 5/10 kg/mm

The BC Racing RM coilover kit Supra A90 (part number C-165-RM-MA) 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 5 kg/mm front and 10 kg/mm rear.

The RM series from BC Racing is made for track days, hill climbs and tarmac rally. On MacPherson struts BC Racing uses an inverted monotube, on other suspension types an upright monotube, always with a digressive piston and fully synthetic oil with a very high viscosity index.

It is a kit for those who mainly use the A90 on track or in competition. For a GR Supra that spends most of its time on the road, the BR and the DS from BC Racing are a more logical choice.

Key benefits

• Inverted monotube on MacPherson: and an upright monotube on other suspension types.
• Digressive piston: firm control over slow body movements.
• Fully synthetic oil: with a very high viscosity index.
• 30-click damping adjustment: compression and rebound simultaneously per damper.
• Spring rate 5/10 kg/mm: the same as the BR and DS kits for the A90.
• Pillowball top mounts at the front: or camber plates, rubber or the original mounting at the rear.
• Rebuildable: the dampers can be rebuilt.
• Track day, hill climb and tarmac rally: the use BC Racing developed the RM for.
