Tank 300 (Cyber Edition) Big Brake Kit Upgrade / TTSPORT Classic 8611
The Tank 300 Cyber Edition is a limited-run, 30,800-yuan flagship off-roader from GWM's Tank brand — the kind of truck that sells out on launch day. But a heavy body-on-frame SUV built for rock crawling and towing puts real demand on its brakes, and the factory setup wasn't built with sustained high-speed or repeated hard stops in mind. This owner went with a TTSPORT TT8611 forged six-piston big brake kit up front, paired with a 330x28mm high-carbon rotor and stainless lines.
The Tank 300 comes with a 2.0T turbo engine (167kW / 387N·m), a ZF 8-speed automatic, three locking differentials, crawl mode, and Tank Turn — serious off-road hardware that also means serious mass to slow down when the truck is back on pavement.
Big SUVs like the Mercedes G-Class run AMG brake upgrades for a reason — more rotor and more clamping force to match the vehicle's weight. This owner chose to back a domestic brand and fitted the TTSPORT TT8611 kit instead.

Why It Works
- The forged aluminum caliper body resists flex under hard braking better than a stamped or cast unit, which keeps pedal feel consistent instead of going soft as the truck's weight loads up the brakes.
- The 330x28mm rotor's curved-vane, heat-treated design pulls more heat out of the disc, cutting down on the thermal expansion that leads to warping and fade during sustained braking.
- At 2.1 kg, the caliper is light enough for its output, and its low minimum-wheel-diameter requirement means it tucks behind the factory 17-inch wheel with no spacers needed.
- Unequal-diameter opposed pistons help apply pad pressure more evenly across the rotor face, which keeps braking linear rather than grabby.
