The A3 Hatch 8P’s φ55 front struts are the larger-bore option for this chassis, built to carry the extra front-end load that comes with hard trail-braking into a hairpin. On a circuit day that load transfer happens corner after corner, not once, and the factory strut was never specified to take it session after session. XYZ Racing’s Circuit Master coilover is the range built around that exact stress cycle.
For an Audi A3 8P doing sustained circuit lap-time work, this sits at the top of the XYZ Racing coilover range for this chassis. It replaces the factory strut and spring assembly front and rear with a height-adjustable, multi-way damped unit designed to hold its settings through a full session rather than a single hot lap.
What this coilover does for your 2004-2012 Audi A3 Hatch 5D 8P
Fitted to the A3 8P, the Circuit Master’s 3-knob damping control gives independent compression and rebound adjustment at each corner, which matters on this chassis because the front end and rear axle load up differently depending on whether you are braking into an apex or getting back on the power out of it. With 9720 total damping combinations across the range, you can run the front firmer than the rear to control the nose-heavy character common across the 8P line, or soften the rear to keep the back axle settled through quick direction changes. Ride height adjusts independently of damping, so you can drop the A3’s centre of gravity for track days without disturbing settings you have already found. On a 2004-2012 A3 Hatch 8P the result is sharper turn-in, less body roll through esses, and a chassis that stays composed as tyre grip and brake temperatures fall away later in a session.
About the Circuit Master coilover
XYZ Racing positions Circuit Master above its Drift Spec and Tarmac Rally ranges as the dedicated circuit option, and the spec reflects that: 3 adjustment knobs per corner combine to produce 9720 distinct damping combinations, which is why XYZ racing teams run this range as their base setup across international circuits rather than a road-biased alternative. The knobs meter through small oil-hole passages rather than a single large valve, and that fine metering is what gives the wide adjustment range. The trade-off is a faint noise from the damper over sharp bumps at speed – a characteristic of the design, not a fault, and not something you will notice mid-corner on smooth circuit tarmac. Every Circuit Master kit for the A3 8P is built to the φ55 spec for this chassis, matching strut bore to the factory mounting points rather than adapting a universal design. It is the range XYZ Racing builds for repeat circuit sessions, not a single trackday outing.
Fitment for the Audi A3 Hatch 5D 8P (2004-2012)
This kit is built for the 5-door A3 Hatch on the 8P chassis (chassis code AU07) across the 2004 to 2012 production run, matched to the φ55 front strut diameter used on this variant. Confirm your car’s strut bore before ordering, since the 8P range was produced with more than one front strut diameter over its life.

Because its 3 adjustment knobs with small oil hole design, when driving through big bumps, the coilover oil will go through small passage which might cause some small noise. This is normal situation. This product is made for circuit tracks and there will be no concern for bumps on the tracks.
