Mercedes-Benz C300 Big Brake Kit Upgrade / TTSPORT Evolution EB6
A Malaysian dealer brought in a Mercedes-Benz C300 for a front brake upgrade, swapping the factory calipers for TTSPORT's Evolution Series EB6 — a split forged six-piston setup paired with a 380mm high-carbon heat-treated rotor. The goal was straightforward: more braking capacity and a firmer pedal without giving up the car's factory 19-inch wheel fitment.
The finished install sits cleanly behind the C300's stock wheel, with the EB6's gold caliper visible through the spokes. TTSPORT designed this kit around a 19-inch-and-up wheel fitment, so no spacers or wheel changes were needed to make it work on this car.

Why It Works
The EB6 uses a two-piece forged aluminum body with a through-bolt design connecting the halves. Forging aligns the metal's grain structure for better tensile strength and durability than a cast caliper, and TTSPORT states this bridge-bolt layout adds roughly 20-30% more structural strength versus a conventional design — which matters most under hard, repeated braking where caliper flex would otherwise soften pedal feel.
- Two-piece heat-insulated pistons, an asymmetric caliper layout, and machined venting help manage the temperature buildup that comes with sustained hard braking.
- Larger, more evenly sized pistons across the six-piston layout spread clamping force more uniformly across the pad, for steadier, more balanced braking.
- The 380mm rotor was matched to the car's 19-inch wheels; TTSPORT also offers 390mm and 410mm high-carbon heat-treated rotors for larger wheel fitments on the same EB6 platform.
