Hardrace Audi B9 Rear Upper Camber Arms
Set your rear camber accurately and keep your Audi B9 stable, grippy, and kind to tyres. These Hardrace rear upper camber arms replace the factory parts and let you fine-tune camber for road or track, or correct alignment after lowering.
Why camber adjustment matters
Camber is the inward or outward tilt of the wheel when viewed from the front. Lowering your car usually adds negative camber, which can help cornering but can also cause inner tyre wear. Adjustable arms let you bring camber back to spec for daily use, or add a performance setup for more grip.
