BMW M2 M3 M4 F80 F82 F87 Caliper Carrier – BTCC Rotor Upgrade for AP Racing CP9660 Caliper | XC3 Engineering

XC3 Engineering Caliper Carrier – BMW M2 / M3 / M4 F80 / F82 / F87

Upgrade the braking system on your BMW F8x M2, M3 or M4 with the XC3 Engineering Caliper Carrier, designed to allow fitment of AP Racing 5000R CP9660 calipers with BTCC-spec brake rotors.

Precision CNC machined from 6082-T6 aluminium and finished in black anodising, this carrier forms the critical mounting interface between the factory F8x front hub and a motorsport-inspired big brake setup.

Designed for clubsport, trackday and high-performance road builds, the XC3 carrier helps ensure the caliper is positioned accurately in relation to the rotor for consistent braking geometry and reliable performance under demanding use.

Why Choose the XC3 Caliper Carrier?

The caliper carrier is a key component within any big brake conversion.

Its role is to securely position the caliper in relation to the brake disc, making accurate machining and correct fitment essential.

Potential benefits include:

• Enables AP Racing CP9660 caliper fitment
• Designed for BTCC-spec rotor upgrades
• Precision CNC machined
• Strong lightweight construction
• Accurate caliper alignment
• Suitable for road and track applications
• Supplied with high-strength mounting hardware
• Designed for OEM F8x front hubs

Precision CNC Machined

Each XC3 caliper carrier is precision CNC machined to ensure accurate dimensions and repeatable fitment.

Correct caliper positioning is especially important in performance braking applications, helping the pad sweep and disc alignment remain as intended.

6082-T6 Aluminium Construction

The carrier is manufactured from 6082-T6 aluminium.

This material provides a strong combination of:

• High strength
• Rigidity
• Low weight
• Durability

This makes it particularly suitable for performance and motorsport braking applications.

Black Anodised Finish

The carrier is finished in black anodising for improved corrosion resistance and longevity.

The finish also provides a clean, high-quality appearance suitable for serious performance builds.

CNC Engraved XC3 Logo

Each carrier features a CNC engraved XC3 logo for a professional finished appearance.

High-Strength Mounting Hardware

Chemi Black 12.9 tensile mounting hardware is included.

This provides a strong and secure mounting solution suitable for the high loads experienced within a performance braking system.

Designed for AP Racing 5000R CP9660 Calipers

The carrier is designed specifically around the AP Racing 5000R CP9660 caliper.

This makes it suitable for F8x owners building a high-performance front brake setup using motorsport-derived components.

BTCC-Spec Rotor Compatibility

The carrier allows the AP Racing CP9660 caliper to be positioned correctly when used with compatible BTCC-spec brake rotors.

This makes it ideal for:

• Trackday cars
• Clubsport builds
• Fast-road performance cars
• Motorsport-style brake conversions

Big Brake Upgrade Foundation

The carrier itself does not increase braking performance on its own.

Instead, it enables the installation of the upgraded caliper and rotor combination required for a complete big brake setup.

A properly configured braking system can help improve:

• Braking consistency
• Heat management
• Resistance to fade
• Pedal confidence
• Repeatability under hard use

Ideal for Track-Focused Builds

This carrier is particularly well suited to F8x builds where braking performance is being upgraded to match increased power, tyre grip or track use.

It is a strong option for:

• F87 M2 track builds
• F80 M3 clubsport setups
• F82 M4 fast-road and track cars
• Semi-slick tyre setups
• Performance brake conversions

Direct Fitment to OEM Front Hubs

The XC3 carrier is designed for BMW F8x models using the factory front hubs.

No alternative hub conversion is required for fitment.

Lifetime Warranty

XC3 Engineering backs this product with a lifetime warranty.

This provides additional confidence in the strength and durability of the component.

Warranty terms and conditions should be checked before purchase.
