WEY VV7 Big Brake Kit Upgrade / TTSPORT Classic 8657
WEY's VV7 packs a 2.0T turbo four making 234 horsepower and 360 Nm of torque into a package that undercuts plenty of luxury SUVs on price — but the factory brakes are still sized for daily driving, not for a car with this much punch behind the wheel. One VV7 owner decided the rest of the car deserved brakes to match, and went with a TTSPORT front six-piston / rear four-piston big brake kit built specifically for the platform's 21-inch wheels.
The setup runs a TTSPORT TT8657 six-piston caliper up front with a 405x34mm high-carbon rotor, and a TTSPORT TT6411 four-piston caliper at the rear with a 380x28mm rotor — plus a TTSPORT electronic parking brake caliper so the VV7's EPB keeps working normally.

Why It Works
The TT8657 caliper — body, bridge bolts, and all — is forged rather than cast, which TTSPORT rates at roughly 30% more rigid than a cast unit. Less flex in the caliper body means the pads clamp harder and more consistently under pressure, so pedal effort needed to get strong braking drops, especially once things get hot. The 405mm curved-vane rotor is sized to clear dust off the friction surface and hold heat better than the stock disc, which keeps fade in check on repeated hard stops.
- Forged six-piston front caliper adds rigidity over the cast factory unit for firmer pedal feel
- 405mm front rotor adds heat capacity and clears dust to reduce fade under repeated braking
- Rear TT6411 caliper retains a linear pedal feel and keeps the factory electronic parking brake operational
- Sized to fit within the VV7's existing 21-inch wheels
The rear TT6411 is one of TTSPORT's more common fitments, built from forged high-strength aluminum with an opposed four-piston layout. Its brake characteristics lean toward everyday and light off-road use rather than pure track duty, and it's spec'd for wheels 18 inches and up — well within range for the VV7's 21s.
