Wilwood
The Porsche brand is steeped in performance automotive and racing history with numerous world records. The early models broke technological barriers with innovative suspension, comfort, and reliability. The air-cooled rear-engine 911 evolved over the next 30 years until the new water-cooled models were introduced in 1999.
Wilwood engineers have developed replacement calipers and complete brake kits using race-proven designs for the early Porsche models to meet the growing demand for hard-to-find, pricey components. Wilwood calipers and kits are bred from a winning race history, dominating circle tracks and road race venues worldwide. Adapting the existing technology to the Porsche platform is a win-win for Porsche enthusiasts and racers. If you are looking for bolt-on calipers or complete brake kits, including rotors, hats, and stainless braided brake lines, Wilwood is rolling out solutions for you. Modern technology and USA manufacturing at Wilwood factories in California provide strong, lightweight forged aluminum calipers, high-performance alloy rotors, and a wide selection of brake pad compounds to keep Porsche models running strong and competitive.
It’s important to note that any brake kit of interest requires your review of the provided wheel clearance diagram on the product detail page before purchase to confirm a proper fit.

Forged Narrow Superlite 4R Front Brake Kit using OE hubs
Motorsports-proven Forged Narrow Superlite Radial mount caliper, with oversize rotor are engineered to bring 1969-89 Porsche 911s performance braking capability on par with the 1974 RS and 930 turbo, using lightweight components and modern USA manufacturing techniques. These kits combine the latest Superlite four piston caliper, used in countless laps of many competition classes, with 12.19” (310mm) diameter GT slotted or SRP series drilled and slotted e-coat rotors, and the positive response, high fade resistance, and easy clean properties of the BP-10 compound Smart Pads. Forged aluminum calipers, mounting hats, and bracket outperform stock parts while weighing less. These kits bolt directly to front struts with 3.00” (76.2mm) spaced mounting tabs without modification. Braided stainless Flexlines are included.
Wilwood engineered these big brake kits around the motorsports proven Superlite calipers for the classic 1969-89 Porsche 911. Larger 310mm (12.19”) iron alloy rotors with forged aluminum mounting hats and Wilwood brackets produce greater brake torque and less fade, while weighing substantially less than OE.
These rigid, forged billet aluminum four piston calipers upgrade the stock 911 to a spec similar to the 1974 RS or 930 turbo, with the added advantage of decades of material, design and manufacturing advancements. Kits are available for both 3.0” (76,2mm) and 3.5” (88,9mm) mounting tabs.
Kit Features:
- Superlite front calipers have been proven in countless road race, circle track and off-road competition classes. These have evolved over decades and been refined through millions of laps.
- Direct bolt-on upgrade for 1969-89 Porsche 911 with no permanent modifications
- Designed to work with OEM master cylinders and rear brakes to maintain proper front to rear brake bias
- Stress-flow forged aluminum calipers with stainless steel pistons for strength and durability
- Offered in gloss Le Mans yellow, black or red powder coat over durable wear-resistant Type-III hard anodized coating
- Big 310mm (12.19”) x 28mm (1.10”) vented rotors for greater brake torque and more thermal capacity (28mm/1.10” larger than OE)
- Precision-machined, low-distortion proprietary iron alloy rotors with 32 cooling vanes, mounted to forged aluminum hats
- Rotors offered with GT slotted, or SRP drilled and slotted faces
- High-performance street BP-10 brake pads
