Lynk & Co 03 Big Brake Kit Upgrade / TTSPORT Racing AP9660
The Lynk & Co 03 was the brand's first sedan and the first car built on the CMA platform, packing a 2.0TD engine and 8-speed automatic good for 254 hp, 350 N·m of torque, and a 0-60 sprint in the mid-5-second range. That kind of straight-line pace deserves brakes to match, so this build swapped the factory calipers for a full front-and-rear TTSPORT big brake kit.

Wheel size on this car is 19 inches, plenty of room to move up to a six-piston front caliper without spacers or wheel changes. The owner went all in: a proper six-piston/four-piston front-and-rear setup instead of just addressing the front axle.

Why It Works

A forged fixed caliper doesn't flex under load the way a sliding single-piston OEM caliper can, so pedal effort goes into clamping the rotor instead of deforming the caliper body — that's the difference between a firm pedal and a mushy one. Stepping up to six pistons up front also spreads clamping force across more pad area, which helps even pressure distribution and pad wear.
- Larger 380x28mm rotors on both axles add mass and surface area, which means more heat capacity and less fade under repeated hard stops.
- Front and rear were upgraded together rather than just the front axle, so front-to-rear brake balance stays proportional instead of overloading one end.
- The rear AP9440 caliper pairs with a Tesla-style small motor, so the car's electric parking brake keeps working after the swap.
- Both calipers clear the factory 19-inch wheels with no spacers needed.
