Product Details

These KSport Version RR coilovers fit the 1988-1991 BMW M3 RWD. The KSport Version RR Coilover Kit is built for 1988-1991 BMW M3 owners who want a track-ready damper without jumping to a remote reservoir setup. It features a monotube design, high-pressure nitrogen charge, and damping curves tuned for grip — so your M3 stays flat through transitions, turns in harder, and uses its tires instead of fighting them.

Full ride-height adjustment and single-knob damping control give you a usable range from street stance to weekend warrior. If the Kontrol Pro feels a touch soft and you're not ready to step up to two-way, the Version RR lives in the sweet spot — a serious coilover for a BMW M3 that sees real driving without turning into a track-only build.

Features

  • Strictly designed and built for Auto Racing
  • Stiffer spring rates and shock valving combined with 20-30mm shorter shock stroke
  • 36 levels of damping which allow you the ability to perfectly dial in your coilover system
  • Collars and upper mounts made from 6061 aluminum with T6 for increased hardness
  • Adjustable spring perch for height adjustment
  • Adjustable lower mount allowing maximum suspension travel
  • Camber adjustment on many models
  • All metal pillowball for added strength and responsiveness
  • Monotube high pressure design for better performance and heat dissipation
  • Electroplated body for added protection from corrosion and rust
