A coilover kit gives the chassis of an MX5 NB (1998 - 2000) more options for tuning ride height and damping character according to use and preference. Because spring and damper work together as one adjustable unit, not only the position of the body changes, but also how weight is distributed during steering, braking and acceleration. Especially in a lightweight roadster, you notice such changes immediately in balance and feedback. When the adjustment of steering and axle components is also just right, a set-up really comes to life.
