A Quick Look at AP Racing
AP Racing is the leading manufacturer of performance brake and clutch systems for road and race cars. The core product range includes clutches, calipers, discs, pads, master cylinders, pedal boxes and air jacks, as well as road and competition brake systems for motorcycles.
Choosing the Right Fit for Your Porsche
Where AP Racing is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.
- Typical reasons to choose AP Racing include upgrading a Porsche’s braking for stronger bite, better pedal feel and improved resistance to fade under hard use.
- Owners often move to AP Racing components when standard brakes overheat, feel inconsistent or struggle with repeated heavy stops on road or track.
- Typical braking issues that prompt an upgrade include brake fade, uneven pad wear, cracked discs, a long pedal after hard use and vibration, often linked to overheated fluid.
- Check wheel and caliper clearance carefully and follow any guidance on pad and disc bedding-in procedures when fitting performance brake components.
- For hard-driven cars, consider suitable high-performance brake fluid and hoses alongside caliper and disc changes, and monitor temperatures if the car is used on track.
Browse by Category
If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.
Brakes — Brake components are renewed to restore stopping performance, address wear or upgrade a Porsche for fast road or track use. Common symptoms include vibration under braking, increased stopping distances, squealing, pulling to one side, warning lights and visible wear to discs and pads.
- Confirm whether the parts are OE-equivalent replacements or performance upgrades for your intended Porsche use.
- Check if discs, pads, fitting kits and sensors should be replaced together and follow the recommended bedding-in process.
Brake Fluid — Brake fluid is changed regularly to maintain boiling point and corrosion protection within the braking system. Old fluid absorbs moisture, reducing boiling point and potentially causing pedal fade, internal corrosion and sticky components.
- Select a DOT rating and specification suitable for how the Porsche is used and verify compatibility with ABS and stability systems where applicable.
- Follow recommended service intervals for fluid replacement and avoid mixing incompatible fluid types.
