- Lightweight billet 6-piston front calipers
- Includes street brake pads, stainless steel brake lines, mounting brackets, and installation hardware
- Designed for street, spirited driving, and track use
Product Description
The APR 370mm 6-Piston Big Brake Kit is a comprehensive front brake upgrade engineered specifically around compatible MQB and MQB EVO vehicles. Rather than adapting an oversized factory brake system from another vehicle, APR designed the complete system around the intended application to maintain proper brake balance and integration with the factory ABS and stability-control systems.
At the center of the system are APR's next-generation 6-piston calipers. The calipers are machined from high-grade aerospace aluminum billet and use a rigid 2-piece construction with six stainless steel pistons. APR uses generative design and engineering analysis to place material where it contributes to strength and rigidity while minimizing unnecessary mass.
The calipers are paired with large 370x34mm 2-piece semi-floating rotors. Each rotor uses a high-carbon iron friction ring with 72 curved directional cooling vanes to increase airflow and manage heat during repeated braking. A slotted rotor surface provides strong initial bite and helps distribute heat while maintaining street-friendly noise, vibration, and harshness characteristics.
The semi-floating rotor design allows the friction ring to expand and contract as temperatures change, helping reduce stress on the rotor and aluminum hat during demanding use. APR also incorporates a Maximum Temperature Recording system into the brakes, giving performance and track drivers useful information when selecting appropriate brake pads and fluid.
The kit arrives with high-performance street pads already installed in the calipers. The pads use a standard replacement size, providing additional options for drivers who want to change compounds for more demanding track use. Braided stainless steel brake lines, billet mounting brackets, and the necessary installation hardware are also included.
Choose Red anodized calipers for a bold performance appearance or Dark Grey hard-anodized calipers for a more understated look with additional durability suited to frequent track use.
Best For: MK7 and MK8 GTI owners looking for a complete high-performance front brake upgrade that delivers improved stopping capability, heat management, pedal feel, and consistency for aggressive street driving and track use.
Why Choose the APR 370mm Big Brake Kit?
The APR 370mm Big Brake Kit is engineered as a complete braking system rather than simply combining larger components. Vehicle-specific engineering helps maintain proper brake balance and compatibility with factory ABS and stability-control systems, while 6-piston billet calipers, 2-piece 370x34mm rotors, stainless steel brake lines, and performance pads provide the hardware needed for substantially more demanding driving conditions.

Frequently Asked Questions
Q: What size are the APR brake rotors?
A: The kit uses large 370x34mm 2-piece semi-floating front rotors.
Q: How many pistons do the APR calipers have?
A: Each front caliper uses six stainless steel pistons.
Q: What caliper colors are available?
A: The kit is available with Red or Dark Grey calipers.
Q: Does the kit include brake pads?
A: Yes. High-performance street pads are included and pre-loaded in the calipers. The system uses a standard pad size, providing additional options when a different compound is desired.
Q: Are stainless steel brake lines included?
A: Yes. Braided stainless steel brake lines are included with the kit.
Q: Can the APR Big Brake Kit be used on the track?
A: Yes. The system is designed for a wide operating range from street driving to demanding track use. Drivers who frequently track their vehicle may want to select a more aggressive pad compound and appropriate high-temperature brake fluid.
Q: Will the APR 370mm Big Brake Kit fit behind my wheels?
A: Wheel clearance depends on wheel diameter, width, offset, spoke design, and other factors. APR provides a wheel fitment template that should be used to verify caliper clearance before ordering.
Q: Does this kit replace the rear brakes?
A: No. This is a front big brake kit and replaces the front brake components only.
