Forza Replacement Brake Disc Ring (Left) - 370mm Audi 8V RS3 & 8S TTRS - FFD.370.34.235.G11.7T.FL

Forza Replacement Brake Disc Ring (Left) - 370mm Audi 8V RS3 & 8S TTRS - FFD.370.34.235.G11.7T.FL

Replacement rotor ring only — requires existing Forza 2-piece centre hat. Designed to replace worn rings on Forza 2-piece assemblies, saving cost vs. buying complete rotors.

Compatibility (Forza Assemblies)

• F2D.370.34.AAR

• F2D.370.34.ABR

• F2D.370.34.ACR

Key Specifications

• Diameter / Thickness: 370 mm × 34 mm

• Side / Direction: Left-hand, directionally curved vanes

• Design: 2-piece floating ring with forward-facing curved slots

• Material: High-carbon cast iron; heat-treated

Engineering Features

High-carbon metallurgy

• Optimal thermal conductivity & heat dissipation

• High resistance to distortion and thermal cracking

• Lower rotor wear; reduced judder and noise (higher damping)

Directionally curved vanes

• Centrifugal pump effect for higher internal airflow and cooler operating temps

• Stronger and more crack-resistant than pillar-vented designs

• Smooth airflow entry/exit for stable temperatures

Heat-treated castings

• Prevents deformation through repeated heat cycles

• Strengthens molecular structure; relieves casting stress

Forward-facing curved slots

• Superior modulation and pedal control

• Lower pad and disc wear; balanced initial bite with longevity

Benefits of the Forza 2-Piece System

• Reduced unsprung mass for improved handling and braking feel

• Lower heat transfer to wheel bearings

• Floating interface helps prevent pad knock-off

• Replaceable rings for cost-effective servicing

• Corrosion-resistant hat finish; heat-paint indicators to monitor peak temps

Applications

Audi

• RS3 (8V) — 2017–

• TTRS (8S) — 2017–
