Lynk & Co 03+ Big Brake Kit Upgrade / TTSPORT Classic 8657S
This Lynk & Co 03+ build, done in partnership with wheel brand Fangye Fu, swaps the stock front brakes for a TTSPORT Classic Series 8657S six-piston kit — a forged fixed caliper and a 380mm carbon, heat-treated rotor tucked behind the car's 19-inch wheels.
The 8657S is TTSPORT's updated take on the original 8657 caliper, with revisions to the piston design, caliper venting, and overall caliper width aimed at broader fitment across sedans, SUVs, MPVs, and performance cars. On this 03+, the kit runs with a vehicle-specific caliper bracket, TTSPORT high-performance street pads, stainless steel brake lines, brake fluid, and the mounting hardware needed for a complete front-axle install.

Compared with the original 8657, the 8657S revises the pistons, adds more caliper venting, and narrows the overall body. The two-piece heat-insulated pistons resist deformation under repeated heat cycling, which keeps clamping force consistent whether the car is doing daily driving or a track day.
Why It Works
- A two-piece forged aluminum caliper body flexes less than a stock caliper under hard braking, so pedal input translates more directly into clamping force instead of getting soaked up in caliper deflection.
- The extra caliper venting improves heat dissipation, which helps keep braking temperatures in check and reduces the risk of fade during sustained hard use.
- The narrower caliper width on the 8657S, combined with a vehicle-specific bracket, lets the kit tuck behind the 03+'s 19-inch wheels without spacers.
- The larger-diameter 380mm carbon, heat-treated rotor adds thermal mass over the stock disc, giving the system more capacity to absorb and shed heat before performance drops off.
