Composite grey hat brake discs are key for Audi’s balance of luxury and performance—fitting models like A4L, Q5L, and S3, they work with Audi’s brake system to handle daily commutes and sporty driving. The composite structure (friction ring + grey steel hat) cuts weight while the grey hat boosts corrosion resistance. Meeting ECE R90 and IATF 16949 standards, our discs match Audi’s OE specs, ensuring safe, smooth braking that aligns with the brand’s quality.
