Upgrade your build with a genuine Audi OEM front brake caliper set from the Audi SQ7 / Q7 4M platform.These calipers are supplied under part numbers 4N0615107AG and 4N0615108AG and are of Akebono 9N type, intended for 400x38 mm front brake discs.

This is an excellent OEM-based big brake upgrade for customers looking for factory-quality braking performance, clean original-equipment appearance, and strong thermal capacity.
The calipers are commonly considered as an OEM retrofit base for selected Audi platforms where a large front brake upgrade is desired.

Retrofit applications must be double verified.Final compatibility depends on bracket design, disc offset, disc thickness, pad profile, hub geometry, and wheel spoke clearance rather than on model name alone.

Why choose this set

This set is a strong option for customers who want a real OEM large-brake solution instead of a generic aftermarket kit.
It works especially well for builds where factory appearance, OEM quality, and large rotor capacity are important.

For retrofit projects, this product is best marketed as an OEM caliper upgrade base rather than a universal direct-fit kit.That keeps the listing accurate and reduces fitment issues on custom applications.

Important notes

Please confirm before ordering:

Vehicle model and year.
Front knuckle and mounting dimensions.
Rotor size and offset.
Wheel diameter and spoke clearance.
Whether brackets are already available for your platform.

This product is intended for OEM replacement or custom retrofit use.

All retrofit applications must be checked individually before installation.

CCB Rotor & Wheel Fitment Guide

Minimum wheel diameter guidance by rotor size. Always validate final fitment using a physical template and measured clearances.

Rotor Size (Diameter x Thickness)	Minimum Wheel Size	Technical Fitment Notes
310mm × 22mm	16-inch	Fits most 16-inch wheels. Installation on 15-inch wheels is possible only with specific low-profile callipers and is not generally recommended.
330mm × 28mm	17-inch	Standard entry-level size for performance brake upgrades. Fits comfortably within most 17-inch alloy wheels.
345mm - 356mm × 32mm	18-inch	Common mid-range size. Requires 18-inch wheels with standard barrel clearance.
380mm × 32/34mm	19-inch	The industry standard for Carbon Ceramic (CCB) and heavy-duty steel systems. Fits most 19-inch wheels; verify spoke clearance for wider callipers.
390mm × 36mm	19-inch (Tight Fit)	Fits 19-inch wheels with high-clearance barrels (flat inner bed). 20-inch wheels are recommended to ensure adequate air gap for cooling.
400mm - 405mm × 36/38mm	20-inch	Requires 20-inch wheels. Ensure the wheel barrel does not taper significantly near the mounting face.
410mm - 420mm × 38/40mm	21-inch	Standard fitment for 21-inch wheels. Can fit select 20-inch motorsport wheels with specialised flat barrel profiles (template verification required).
440mm × 40/42mm	21-inch (Minimum)	Extreme fitment. 21-inch is the absolute minimum requirement. 22-inch wheels are strongly advised for safe operating clearance and heat dissipation.

Essential Clearance Requirements

To ensure safety and prevent damage to components, please observe the following industry-standard tolerances when measuring your wheels:

Radial Clearance (Barrel): A minimum gap of 3mm is required between the top of the calliper and the inner wheel barrel to account for heat expansion and wheel deflection under load.
Axial Clearance (Spokes): Ensure a minimum of 3mm clearance between the face of the calliper and the rear of the wheel spokes.
Balance Weights: Ensure wheel balancing weights are positioned so they do not foul the brake calliper. We recommend placing weights outboard of the calliper zone for tighter fitments.

Important Fitment Disclaimer

The wheel sizes listed above represent minimum technical requirements based on standard barrel profiles. Due to significant variation in alloy wheel designs, particularly spoke curvature (X-factor) and inner barrel contours, meeting nominal diameter alone does not guarantee compatibility.

We strongly recommend verifying clearance instrumentally using printable fitment templates rather than relying only on visual estimates or stated wheel specifications. Please ensure at least 3mm clearance in all directions to account for thermal expansion and dynamic wheel deflection.
