Description
BC Racing BR coilover kit Mazda MX-5 ND (15+) 5/2.5 kg/mm
The BC Racing BR coilover kit MX-5 ND (part number N-34-BR-RS) is a coilover kit adjustable in height and damping, also simply called a coilover, for the Mazda MX-5 ND, from model year 2015. The spring rate is 5 kg/mm front and 2.5 kg/mm rear.
The BR is BC Racing’s all-round coilover kit, made for road use with the occasional track day or autocross. For the MX-5 ND that means a tighter, lower roadster that you simply keep driving every day.
On the original suspension an ND leans considerably in corners. This kit gives the car more support: monotube dampers with a linear piston, 30-click damping adjustment and a ride height that you set independently of the spring preload.
Key benefits
- Ride height independent of spring preload: lowering via the damper body.
- 30-click damping adjustment: compression and rebound set together.
- Linear piston: predictable damping that increases evenly.
- Spring rate 5/2.5 kg/mm: the BR kit that BC Racing UK recommends for the MX-5 ND.
- Patented concave lower lock ring: the ride height stays fixed.
- Rubber top mounts at the front: rubber or the original mounting at the rear.
- Road and track: suitable for daily use and the odd track day.
- Rebuildable: the dampers can be rebuilt.
