Product Details

The Function and Form Type 4 Coilovers for the 2008-2016 Audi A4 (8K) are the brand's premium coilover system, built around an inverted monotube damper for OE-plus refinement and high-end ride control. Engineered to give your Audi A4 a planted, composed feel, these A4 coilovers combine a clean lowered stance with the smooth, controlled damping that makes the A4 8K feel composed on any road.

Also branded Function & Form / F2 Suspension, the Type 4 uses a large inverted piston and long-stroke design to add travel, cut unsprung weight, and keep damping consistent when you drive hard. One-way adjustable rebound and compression plus full ride-height adjustment let you tailor exactly how the 8K A4 sits and responds, in a bolt-on, preload-ready kit. Backed by a 24-month warranty with free U.S. shipping on orders over $250.

Features

  • Premium full-bodied coilover kit built around an inverted monotube damper for OE-plus refinement
  • Large 40mm inverted piston increases damper strength and reduces unsprung weight for crisper response
  • Long-stroke design adds suspension travel for a smooth, controlled ride in any condition
  • One-way adjustable rebound and compression to match your vehicle, road and driving style
  • Optimized heat dissipation keeps damping consistent during hard or sustained driving
  • Ride height adjustable from the lower mount, independent of spring preload
