GAC GM6 Big Brake Kit Upgrade / TTSPORT Classic 8611
MPVs are having a moment, and the Trumpchi GM6 is a good example of why — a roomy cabin, a comfortable ride, and a 1.5T engine putting out 124kW and 265N·m, all clean enough to meet National VI emissions. But a big, family-hauling MPV still needs brakes that can match its weight. During braking tests on this GM6, the softer suspension tuning let the body lean forward noticeably, with a fair amount of nose-dive under hard stops. The owner's shop specified a TTSPORT TT8611 six-piston kit up front to give the car a firmer, more controlled stop.
The build swapped the stock front brakes for TTSPORT's TT8611 forged six-piston caliper, paired with a 330x28mm high-carbon heat-treated rotor and stainless steel brake lines — all fitted behind the GM6's factory 17-inch wheels.

Why It Works
The TT8611 is built as a slim-profile caliper specifically so it clears the smallest wheel diameters TTSPORT sells for — 17 inches and up — which is why it worked on the GM6's factory wheels with no spacers or wheel swap needed. A forged six-piston caliper also clamps more evenly across the pad than a stock single- or twin-piston sliding caliper, which cuts down on the flex that makes a pedal feel soft under hard braking.
- Shorter stopping distance from the larger 330x28mm rotor and six-piston clamping force
- Faster, firmer pedal response with braided stainless steel lines replacing rubber hoses
- Fits behind the GM6's stock 17-inch wheels, no wheel change required
Every TT8611 kit arrives with the forged caliper, rotor, and hardware ready to bolt on — no machining or spacer shims needed to clear the GM6's factory hub and wheel offset.
