Volkswagen Touareg Big Brake Kit Upgrade / TTSPORT Classic 8703
This Volkswagen Touareg runs a 3.6L supercharged V6 good for 320 hp and 440 N·m, with a 0-100 km/h time around 7 seconds — quick for an SUV that weighs over two tons. That combination of power and mass puts a lot of strain on a stock braking system, especially off-road or during spirited driving, which is why the owner moved to a TTSPORT Classic Series 8703 big brake kit up front.
The upgrade swaps the factory front setup for a TTSPORT 8703 cast monobloc six-piston caliper paired with a 380mm x 34mm high-carbon heat-treated curved-vane rotor and TTSPORT stainless brake lines. Everything is fitted behind the truck's factory 20-inch wheels.

Why It Works
The TT8703 caliper is a one-piece cast unit rather than a bolted two-piece body. A single casting flexes less under the clamping loads a heavy SUV like the Touareg generates, so more of the pedal input goes into squeezing the pads instead of stretching the caliper.
- Six-piston, one-piece cast caliper resists self-deformation under hard, repeated braking.
- A larger 380mm rotor increases braking torque at the wheel, which shortens stopping distance without needing more clamping force.
- More rotor mass sheds heat faster during hard or repeated braking, reducing the risk of fade.
- Stainless lines resist expansion under pressure compared with rubber hose, which helps keep pedal feel consistent.
