Volkswagen ID.6 X Big Brake Kit Upgrade / TTSPORT Evolution EB10
EVs carry a lot more curb weight than the gas-powered vehicles they replace — battery packs alone can add several hundred pounds — and that extra mass all has to be scrubbed off by the brakes. On a Volkswagen ID.6 X running fully loaded with a family aboard, the factory brake calipers can start to feel overwhelmed well before you'd expect, especially in repeated stops or hard braking. This build swaps in a TTSPORT Evolution Series EB10 ten-piston big brake kit up front to restore some margin.
The vehicle here is a Volkswagen ID.6 X on 21-inch wheels — plenty of clearance to work with, which matters when you're stepping up to a ten-piston front caliper and a larger rotor.

Why It Works
The EB10 is built as a two-piece forged caliper with through-bolted reinforcement bars running along both sides of the body. That structural bracing keeps the caliper from flexing under hard pedal load, which is a big part of why a forged fixed caliper feels more consistent than a stock sliding caliper as brake force spreads more evenly across the pads.
- Asymmetric piston layout balances clamping force across the pad contact area, for a more linear brake feel and better stability under braking.
- Two-piece heat-insulated pistons with dust boots and optimized seals keep pedal feel consistent under sustained hard use, not just on the first stop.
- An open, lightweight caliper design improves heat dissipation, which helps limit thermal fade and keeps braking performance repeatable.
The 420mm high-carbon, heat-treated rotor adds mass and surface area over the stock disc, giving the system more thermal capacity to absorb and shed heat — a straightforward but effective way to fight fade on a heavier EV. TTSPORT notes the EB10 can also be paired with a 440mm rotor depending on wheel size, if a given build has the clearance for it.
