Product Details

The KSport Version DR Drag Race Coilover Kit is purpose-built to launch the 1999-2005 BMW 3 Series harder and straighter. Soft front spring rates and drag-specific damping let the nose lift to plant the rear tires, while stiffer rear valving controls squat and keeps power going through the contact patch — the difference between spinning and hooking when the tree turns green.

Full height adjustment lets you set pre-load and corner weights for your BMW 3 Series's driveline layout, and single-knob damping adjustment makes tuning between passes fast. If you're building a dedicated drag car or a street/strip 3 Series that still has to drive home, the Version DR is a coilover system designed to put power on the ground.

Features

  • Spring rates and shock valving specific for Drag Racing
  • 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
  • All metal pillowball for added strength and responsiveness
  • Adjustable lower mount allowing maximum suspension travel
  • Monotube high pressure design for better performance and heat dissipation
  • Electroplated body for added protection from corrosion and rust
