Lynk & Co 03 Big Brake Kit Upgrade / TTSPORT Classic 5410

TTSPORT's product lineup moves fast, and the newest Evolution-series caliper — the titanium-tone TT5410 — is already showing up on customer cars. This Lynk & Co 03 install gives a clear look at how the four-piston TT5410 kit sits inside a factory 18-inch wheel, what's actually in the box, and why the finish isn't just for looks.

The project: a brake upgrade on a Lynk & Co 03 running 18-inch wheels. The parts going on: the TT5410 forged four-piston caliper, a 355mm x 32mm Dacromet-coated curved-vane rotor, and TTSPORT stainless steel brake lines.

Vehicle & Kit Specs

The titanium-gold oxidized finish and forged construction are unique to this caliper family, and the flower-pattern (multi-lobe) pistons carry through the same design language. Positioned as a dual-duty street-and-track caliper, the TT5410 is built to handle more than a standard replacement caliper while staying flexible enough for daily driving.

Why It Works

• A forged caliper body resists flex under hard braking better than a cast one, so pedal input translates more directly into clamping force.
• The 355mm x 32mm rotor adds mass and swept-area leverage over a smaller stock disc, giving the system more heat capacity to resist fade.
• The Dacromet coating and baked-yellow treatment protect the rotor surface that pads don't sweep, keeping the disc from rusting unevenly over time.
• Stainless steel lines resist the swelling that rubber hoses experience under pressure, helping keep pedal feel consistent.
• The kit fits within the Lynk & Co 03's factory 18-inch wheel barrel, as confirmed on this install.
