We've re-engineered a 930 style caliper with specific enhancements for direct fitment to the 911. Our 930-ERX calipers are an updated version of the venerable 930 brakes which have long been the benchmark for performance.

Porsche 911 / 912 / 930
*** For 1965-73 use 3.5" spacing struts
The 930 Brake Upgrade
930 brakes have been an awesome upgrade for 911 cars in terms of thermal capacity and pedal feel. The four piston calipers and massive 32mm front / 28mm rear rotors give incredible stopping power.
In addition to excellent stopping power, they have a period correct retro race look, retain the parking brake functionality, and even fit under many 15 inch wheels. This is why 930 brakes have traditionally been the sought-after upgrade for 911 racecars, and high end/high powered street car builds.
However fitting them has traditionally been difficult – requiring custom machining (due to differences in 930/911 caliper bolt spacing), wheel clearance issues, and limited availability.
Our re-engineered 930-ERX type calipers keep everything that's great while fixing all the issues. And they accept readily-available 930 type pads, rotors, and master cylinders.
930-ERX Enhancements over Original 930 Calipers
✓ No caliper machining is required for 911 trailing arm fitment.
✓ Our rear calipers have the correct 3.0 inch bolt spacing and radial position to mount directly onto '69-'89 911/912 trailing arms.
✓ The front and rear caliper cooling fins are low profile such that they do not interfere with Fuchs wheel spokes without the need for wheel spacers.
✓ A modern staggered piston design is used for even pad wear on our 930-ERX calipers. Original 930 calipers used same size pistons, which caused pads to wear in a taper.

930-ERX Fitment and Compatibility
The front calipers have 3.5 inch bolt spacing and bolt directly to front struts as equipped on 911 and 912 cars from '72-'89 and 911 S models prior to '72. Early front struts that have 3.0 caliper bolt spacing can convert to 3.5 inch struts, contact us for details.
The rear calipers have 3.0 bolt spacing for direct fitment to 911 and 912 trailing arms from '69-'89 including aluminium and steel trailing arms.
Front and rear calipers accept standard 930 brake pads and standard 911 brake hoses.
Rear calipers use standard type 930 rotors part 930-352-046-01
Front calipers fit with regular 911 hubs and use early type 930 floating rotors with our hat kit #2190005 (floating) or #2190010 (fixed), or late 930 hubs with late 930 fixed rotors.
Use standard 930 master cylinder on '77-'89 911 cars equipped with brake booster, or our master cylinder kit #2190011 for pre-77 cars with non-boosted brakes.

Porsche Brake Calipers | Design911 Precision Replacement & Performance Upgrades for Stopping Power & Control
Brake calipers are a vital part of your Porsche’s braking system — responsible for clamping the brake pads against the disc to create friction and slow the car safely and efficiently. They play a key role in delivering the sharp, responsive braking feel Porsche is renowned for. Whether you’re restoring a classic model or enhancing a modern performance car, maintaining or upgrading your calipers ensures consistent stopping power and driving confidence.
At Design911, we offer a wide selection of brake calipers engineered for precision performance, exact fitment, and long-term reliability. Each caliper is designed using high-quality materials to provide superior heat dissipation, even pressure distribution, and enhanced braking control. Ideal for road, track, or restoration projects, our calipers deliver the perfect blend of safety, strength, and Porsche performance heritage.
What Do Brake Calipers Do?
Brake calipers are the heart of the braking system, converting hydraulic pressure into mechanical force to bring your Porsche to a controlled stop.
Core Functions:
• Apply pressure to the brake pads for effective friction and deceleration.
• Ensure even braking force across each wheel.
• Maintain consistent braking feel and performance under heat and load.
• Work with brake discs and pads to optimise stopping distance.
• Provide responsiveness and control during aggressive driving or track use.
A well-functioning brake caliper guarantees stability, safety, and precision every time you hit the brakes.
Why Do Brake Calipers Fail or Degrade?
Over time, brake calipers are exposed to extreme heat, pressure, and environmental conditions — all of which can cause performance degradation or mechanical failure.
Common Causes of Failure Include:
• Corrosion or rust on pistons and seals.
• Leaking hydraulic fluid from worn seals or connections.
• Uneven brake pad wear due to sticking pistons.
• Fading performance from heat saturation and lack of maintenance.
• Physical damage from impact or excessive vibration.
When calipers fail, braking performance becomes inconsistent or unsafe — making replacement or refurbishment essential for maintaining control and confidence.
Why Replace or Upgrade Your Porsche Brake Calipers?
Replacing old or worn brake calipers restores your Porsche’s braking precision and safety. Upgrading to performance calipers can further enhance stopping power, consistency, and resistance to brake fade. Design911 offers options tailored for both daily driving and motorsport use.
Key Benefits:
• Restores even and powerful braking performance.
• Improves safety and pedal feel during high-demand conditions.
• Enhanced heat management and durability.
• Available in performance and original-spec styles.
• Direct-fit design for Porsche-specific applications.
• Perfect for road, track, or restoration builds.
