Porsche Panamera Big Brake Kit Upgrade / TTSPORT Classic 8703
The Porsche Panamera does the 0-60 sprint about as well as any four-door on the road, but the source case makes a fair point: getting to 100 km/h fast is only half the equation. Hauling it back down to zero, repeatedly, without the pedal going soft, is the part that actually separates a fun car from a fast one. This install swaps in a matched front and rear TTSPORT big brake kit to close that gap.

The Panamera's rounded, panel-clean nose and four-door GT layout hide a lot of mass behind those factory 20-inch wheels — mass that stock brakes have to manage lap after lap, stop after stop.
Vehicle & Kit Specs
This is a full axle-to-axle upgrade: a six-piston front kit and a four-piston rear kit, both built as a matched, one-piece caliper set rather than two unrelated parts bolted on separately.
| Item | Specification |
|---|---|
| Vehicle | Porsche Panamera, factory 20-inch wheels |
| Front caliper | TTSPORT TT8703 six-piston caliper (front axle) |
| Front rotor | TTSPORT 405x34mm Dacromet-coated curved-vane rotor |
| Rear caliper | TTSPORT TT8903 four-piston caliper (rear axle) |
| Rear rotor | TTSPORT 380x32mm Dacromet-coated curved-vane rotor |
| Kit design | Front and rear calipers engineered as a matched set for a coordinated, one-piece install |

Both rotors get a Dacromet coating, an anti-corrosion treatment that keeps the friction face cleaner over time, plus a curved-vane face design that helps sweep debris and boosts contact between rotor and pad.
Why It Works
- Bigger rotors (405mm front, 380mm rear) carry more thermal mass than the factory discs, which helps resist fade when the Panamera is worked hard through repeated stops rather than a single panic brake.
- The curved-vane rotor face increases the contact area and cleanliness between pad and disc, which the source ties directly to more usable friction and stronger, more consistent braking.
- Front and rear calipers were sized to fit behind the Panamera's factory 20-inch wheels, so the whole kit installs as a coordinated axle-to-axle upgrade rather than a front-only patch.
