SF Racing Sport Coilovers for the 2004-2005 Audi S4 Cabriolet AWD (B6/8E) are the best coilovers available for street-driven cars. SF Sport Coilovers were designed to give a wide range of ride height adjustability without reducing the spring travel. Each corner of the car has 32 levels (or clicks) of damping adjustability. This combines both the rebound and compression into one adjustment knob. The coilovers also use rubber top mounts to help reduce the noise that typically comes with high performance aftermarket coilovers. SF Coilovers come standard with an anodized coating to protect against rust and corrosion caused by extreme use and harsh external elements.

SF Racing parts are manufactured from high quality products sourced from around the world while still maintaining a very affordable price. SF Racing Sport Coilovers are the perfect setup for your daily driver.

Features

  • Monotube Damper Design – Improves heat dissipation and reduces oil leakage.
  • 32-Level Adjustable Damping – Fine-tune rebound and compression for ideal ride quality.
  • Adjustable Ride Height – Lowers 1-2.5 inches below factory height without sacrificing suspension travel.
  • Independent Lower Mount Adjustment – Maintains shock and spring integrity while adjusting height.
  • T6-6061 Aluminum Construction – Lightweight, corrosion-resistant anodized top mounts, perches, and collars.
  • Electroplated Shock Body – Zinc-coated for rust protection.
  • Low-Friction, Pressure-Resistant Housing – Ensures smooth damping and longevity.
  • Pillowball or Reinforced Rubber Top Mounts – Reduces noise while improving handling.
  • SAE9254 Japanese Cold-Wound Springs – Durable and consistent performance.
  • Japanese NOK Seals & Italian IP Damping Oil – Prevents leaks and ensures high-performance damping.
  • Integrated Dust Boots & Bump Stops – Protects components from debris and wear.
  • 100% Bolt-On Replacement – No modifications required (unless otherwise stated in the Specifications section).
