$5.84

This Audi TTS 4-piston front brake retrofit kit is designed to upgrade MK7 MQB vehicles originally equipped with smaller single-piston front brakes. By combining OEM Audi TTS fixed calipers with larger 340×30mm front rotors, this kit delivers a significant improvement in stopping power, heat capacity, and pedal feel compared to factory 312mm brake setups.

The TTS 4-piston caliper features an integrated carrier design, allowing it to bolt directly to MQB front steering knuckles without the need for custom brackets or machining. This makes it an ideal upgrade for MK7 GTI, Golf, Sportwagen, and Alltrack models looking for big-brake performance using factory-engineered components.

In addition to improved braking performance, the TTS calipers are lighter than the factory single-piston calipers and carriers. Reducing unsprung weight helps improve steering response, handling, and overall vehicle dynamics while maintaining OEM reliability and serviceability.

This kit provides performance comparable to many aftermarket big brake kits on the market, at a fraction of the cost, making it an excellent option for spirited street driving, track days, or performance-oriented daily drivers.

Wheel Clearance Note: Most OEM wheels tested require 10mm spacers to clear the Audi TTS calipers. Wheel clearance should be verified prior to installation, especially when using factory or smaller-diameter wheels.

Brake Component Weight Comparison:

  • MK7 GTI 312mm single-piston caliper & carrier: ~11.7 lbs
  • MK3 Audi TTS 4-piston caliper (integrated carrier): ~9.8 lbs

TTS 4-Piston Brake Kit Includes:

  • OEM Audi MK3 TTS front 4-piston brake calipers (left & right)
  • OEM Audi TTS front brake pads
  • StopTech slotted front brake rotors (340×30mm, left & right)
  • Front caliper carrier mounting bolts (set)
  • Front rotor set screws
  • Front dust shields for 340mm rotor conversion (left & right)
  • Stainless steel front brake lines
  • Motul RBF 600 high-performance brake fluid

This kit is intended as a front brake upgrade for MQB vehicles and is not a factory replacement package. Proper installation, wheel fitment verification, and brake bedding procedures are recommended to ensure optimal performance and safety.
