COILOVERS BR / BC RACING / AUDI RS4

BC Racing BR coilovers for Audi RS4

The BC Racing BR coilovers for the Audi RS4 are designed to improve handling, driving precision and body control during sporty road driving and intensive track use. Drawing on BC Racing’s motorsport experience, these adjustable dampers offer an excellent balance between performance, versatility and reliability.

Purpose of the part

Coilovers replace the original suspension components to allow precise ride-height and damping-firmness adjustment. They control body movement, improve tyre contact and optimise stability during braking, acceleration and cornering.

Symptoms or consequences of worn or unsuitable suspension

• Deteriorated handling and lack of precision in corners
• Excessive body roll during changes in cornering load
• Loss of traction or grip during sporty driving
• Potentially longer braking distances due to poor tyre contact with the road
• Uneven tyre wear
• Worn dampers causing bouncing, instability or discomfort

Benefits of replacement

• Clear improvement in driving precision
• Reduced body roll and improved high-speed stability
• Height adjustment independent of spring preload
• Can be adapted for road, sporting or trackday use
• 30-position firmness adjustment to adjust rebound and compression
