THE RSR LOOK. KEEP YOUR STOCK ROTORS.
For the classic Porsche owner who wants the unmistakable finned 917/RSR-style brake caliper without replacing the entire brake system: this configurable caliper offering lets you order just the front pair, just the rear pair, or a discounted set of all four Pro-System four-piston RSR-style calipers. Designed for use with compatible original-style stock rotor arrangements, it gives 911 owners a compelling path to a vintage motorsport appearance without automatically requiring a new two-piece rotor package.
Choose a front pair, a rear pair, or all four calipers. Choose the correct rear lug spacing: 3.0-inch short lug for compatible standard 911 rear mounts, or 3.5-inch long lug for compatible 930-style rear mounts. Stock-rotor compatibility is application-specific: confirm rotor diameter, thickness, offset, front strut mounting, rear trailing-arm mounting and wheel clearance before ordering. Not every factory rotor used across 1975–1989 911/930 models is interchangeable.
15-inch and 16-inch Fuchs: Pro-System RSR calipers have been fitted beneath these vintage wheel sizes in suitable configurations. Exact wheel barrel, spoke, offset and spacer clearance must be checked for your particular build.
What Makes These Different?
-
Period-correct finned styling: classic 917/RSR-inspired silhouette, ideal for 911 SC, Carrera and RSR-style builds.
-
Retain compatible stock rotors: no requirement to buy Pro-System two-piece rotors as part of this caliper package.
-
Both axles included: two front and two rear four-piston calipers, not a single-axle set.
-
Two rear mounting configurations: 3.0-inch and 3.5-inch lug spacing.
-
Serviceable friction system: RSR/930-style pad profile, with pad selection matched to intended use.
