XYZ Racing Street Advanced Coilovers — Audi A6 4B/C5 1997-2005

The C5-generation A6 left the factory tuned for autobahn cruising, with soft, long-travel suspension that floats over distance but wallows the moment you ask it to change direction with intent. The XYZ Racing Street Advanced coilover for the Audi A6 4B/C5 exists to close that gap: ride height and damping you set yourself, without throwing away the long-haul composure these cars are bought for.

Carrying an inline-five, V6 or the heavier V8 ahead of the front axle, the 4B/C5 noses in under braking and leans hard mid-corner more than most owners want. This is the street-biased kit in the range, giving you the adjustment to firm up that front-end movement, lower the stance, and keep the body flat through a bend while staying civil on a broken British B-road.

What this coilover does for your 1997-2005 Audi A6 4B/C5

After installation you feel it first in body control: less dive when you brake from speed, far less roll as the long bonnet settles into a corner. The height adjustment lets you take out the factory arch gap and lower the centre of gravity, which is where most of the handling gain on a heavy quattro saloon or Avant comes from. With 720 damping adjustment settings on tap, you can run the dampers soft for a motorway commute, then wind in more control for a weekend drive or a track day, all without changing a single component. The result is a 4B/C5 that turns in with intent yet still soaks up expansion joints and potholes day to day.

About the Street Advanced coilover

The Street Advanced is XYZ Racing’s road-focused coilover, developed over several years by the company’s engineering team and refined through international competition before reaching production. It pairs a fully height-adjustable threaded body with 720 damping settings, so compression and rebound behaviour can be matched to the surface and the use case rather than fixed at the factory. The brief is deliberately broad: a kit suited to normal road driving that still has the range to handle occasional track use. Construction and adjustment are built for owners who want to control how the car rides instead of accepting the standard soft-sprung setup. It is the kit for the A6 driver chasing pace and precision while keeping the car usable every day.
