Description
Mazda ND MX-5 (15+) BC Racing DS coilover kit 5/2.5 kg/mm
The BC Racing DS coilover kit MX-5 ND (part number N-34-DS-DS) 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.
BC Racing’s DS series is track-focused and intended for an MX-5 ND that often goes on track. The heart of the kit is a digressive piston that damps extra firmly at low piston speeds, between 0 and 50 mm/s.
As a result the light ND stays more composed on turn-in, under braking and when accelerating out of a corner. You set the damping in 30 clicks and adjust the ride height independently of the spring preload. The satin chrome damper bodies make the DS recognisable.

Why choose this DS coilover kit MX-5 ND?
An ND on track calls for damping that keeps the body under control. The digressive piston of this kit does that during the slow body movements that determine the balance, and with 30 clicks you tune the car to the circuit of the day. On the way home the kit remains comfortable on the road.
