Product Details

The KSport Asphalt Rally AR Coilover Kit is engineered for the abuse of tarmac rally stages and hard-driven back roads — exactly the conditions that break softer street coilovers on the 2009-2016 BMW Z4. Inverted monotube shocks, extended stroke, heavy-duty internals, and large shock bodies mean more oil volume, better heat dissipation, and the kind of durability that survives a weekend of stage driving.

For BMW Z4 owners chasing points on tarmac or just wanting a coilover that doesn't fade after a spirited drive, the Asphalt Rally AR delivers the consistency real competition demands. Full ride-height adjustment and fine damping control give you the range to build a setup around your tires, your tarmac, and your driving style.

Features

  • Rally AR Spec coilover kits are designed specifically for asphalt rally competition.
  • Inverted steel shock absorber for increased response and heat dissipation
  • Large 55mm shock bodies and increased shock fluid volume for better cooling
  • Heavy duty steel lower mounts for stronger protection under aggressive track driving
  • All metal pillowball for added strength and responsiveness
  • 36-way adjustable damping
  • Collars and upper mounts made from 6061 aluminum with T6 for increased hardness
  • Adjustable spring perch for height adjustment
  • Camber adjustment on many
  • Monotube high pressure design for better performance and heat dissipation
  • Electroplated body for added protection from corrosion
  • Dust boot to protect damper seal
