Audi B9 RS4 / RS5 375x36mm Front Brake Discs for track-focused road cars. Two-piece floating brake disc construction helps manage heat, reduce fade, and improve braking consistency under repeated hard use.
Made to order. Production and dispatch usually take about 30 days from order confirmation.
Brake disc measurement: 375×36mm, sized for the B9 RS4/RS5’s factory big-brake package.
Two-piece floating construction: an aluminium bell decoupled from a high-carbon cast iron friction ring, cutting unsprung weight and letting the disc expand under heat without warping.
Built for the RS4/RS5’s typical use case: fast-road and track-day driving, where the factory disc is prone to fade after repeated hard stops.
Pairs with OEM-fitment RS4/RS5 calipers, no bracket or caliper swap needed on a stock car.
Fits Audi B9-generation RS4 Avant and RS5 Coupe/Sportback with the factory big-brake option. Always confirm your exact caliper part number and disc bell diameter before ordering, B9 cars built across different model years shipped with more than one front brake package, and we want to get this right the first time.
