Lynk & Co 03 Big Brake Kit Upgrade / TTSPORT Slim SL6
The Lynk & Co 03 was never meant to be a compromise. Built on the CMA platform shared with Volvo, backed by a WTCR-winning racing pedigree, and available with a 2.0T/8AT 03+ variant that hits 0-62 in 5.9 seconds — this is a car with genuine performance intent. But like every quick sedan eventually reveals, the factory brakes are usually the first thing that runs out of margin. This case swaps in a TTSPORT Slim Series SL6 six-piston front kit that bolts straight up behind the car's stock 18/19-inch wheels, no flange adapter required.
The 03 and 03+ built their reputation on a stiff CMA chassis and sharp factory suspension tuning. Once the drivetrain and chassis are already dialed in, brakes become the obvious next upgrade — especially for owners who take the car onto mountain roads or the occasional track day.

Getting a six-piston caliper behind an OEM wheel without a flange isn't a matter of luck — it comes down to scanning the wheel's inner barrel, controlling caliper body volume, and shaping the bracket to match. That's the engineering work behind the "direct fit" claim on this kit.
Why It Works
- Bolts up to the factory 18/19-inch wheel with no flange adapter and no change to wheel offset (ET) — avoiding the extra bearing load and steering vibration risk that flanged spacers can introduce.
- The forged aluminum caliper body flexes less under load than a stock sliding caliper, so pedal input translates more directly into clamping force — a firmer, more linear pedal instead of a spongy one.
- Six pistons spread clamping force more evenly across the pad, and the larger 355mm floating rotor gives the system more thermal mass, which helps resist the fade that comes with repeated hard stops on a mountain road or track.
- The result is a pedal that's sensitive at the top of travel and firm underfoot deeper in — useful both for smooth daily stops and for confidence when braking hard from speed.
