Product Details

ST coilovers by KW are constructed of high grade, galvanized steel, and feature a 5 year limited warranty. With engineering tailored specifically to your vehicle, preset dampening and height adjustability provide a good balance between performance and ride comfort.

Features include:

  • Adjustable composite spring seats
  • Tempered high strength springs
  • Compression bump stop with integrated dust boot
  • Hardened chrome piston rod
  • Noise damping, corrosion resistant spring cap
  • Galvanized Zinc plated strut housings for corrosion resistance
  • All ST coilovers meet German TüV standards
  • 5 year limited warranty to the original purchaser
  • Special Note: Audi vehicles equipped with Electronic Damping Control have front and rear OE dampers with electrically-operated actuators that change damping, on command.

    Installing coilovers without similar actuators creates an open-circuit in the control harness to each of the four dampers; this change will turn on a dashboard warning light.

    To prevent dash light illumination, a set of four resistors must be mounted and connected to the open harness plugs at each wheel. A complete set of circuit resistors is available from ECS Tuning (ES2608438) for installation with both KW and many other coilover kits. The resistors come with mounting brackets and exact-fit original equipment connectors. Adding them is a simple plug-and-play installation that will keep the dash light off.
