MG6 Big Brake Kit Upgrade / TTSPORT Classic 5440
MG built the MG6 to go after the Civic, and the 1.5T engine under the hood backs up the marketing. A sedan that gets sold on straight-line speed needs brakes that can match it, which is why this MG6 owner swapped the stock front setup for a TTSPORT Classic 5440 big brake kit. Here's what went on the car and why it matters.
The build stays on the front axle: a TTSPORT Classic 5440 forged four-piston caliper, a TT362 rotor measuring 362mm x 32mm, and stainless steel brake lines. Nothing exotic, just a proven combination sized to work behind the car's stock 18-inch wheels.

Why It Works
A two-piece forged aluminum body is stiffer than the stamped-steel single-piston sliders MG6 ships with from the factory, so caliper flex under hard braking drops and pedal feel firms up. The four star-profile pistons, run without dust boots, clamp more evenly across the pad and shed heat faster than a sliding single-piston design.
More rotor, more capacity
Stepping up to the TT362 rotor — 362mm across and 32mm thick, with curved cooling vanes — adds swept area and thermal mass over the stock disc, which is what actually slows brake fade on repeated hard stops rather than just looking bigger.
Still an OEM-wheel fit
- Kit clears the MG6's stock 18-inch wheels as installed
- Vehicle-specific caliper bracket keeps the geometry correct without spacers
- Stainless lines replace the factory rubber lines for a firmer, more consistent pedal
