Porsche Taycan 4 Cross Turismo Big Brake Kit Upgrade / TTSPORT Racing Series
Porsche's Taycan 4 Cross Turismo pairs EV torque with wagon-like versatility, but that combination puts real strain on a brake system that has to shed a lot of heat and mass every time it slows down. For an owner pushing this car harder, the factory setup needed backup — so the build went with a big-diameter, carbon-ceramic front-and-rear package built around a ten-piston front caliper.
The goal here wasn't just bigger rotors — it was matching rotor mass and caliper clamping force to the car's weight and power so the brakes stay consistent lap after lap, not just for one hard stop.
Vehicle & Kit Specs
| Item | Specification |
|---|---|
| Vehicle | Porsche Taycan 4 Cross Turismo |
| Front caliper | Ten-piston forged monobloc caliper (new) |
| Front rotor | TTSPORT 440mm LCCB carbon-ceramic rotor |
| Rear caliper | OEM Porsche four-piston caliper (retained) |
| Rear rotor | TTSPORT 410mm LCCB carbon-ceramic rotor |
| Fitment | Direct bolt-on install, no additional modification required |
Up front, the 440mm rotor and ten-piston caliper give the car a big footprint for pad contact area and heat capacity — the two things that matter most when you're repeatedly hauling a heavy EV down from speed. Out back, the 410mm rotor keeps braking balance in check without needing to swap the factory Porsche four-piston caliper, which keeps the rear brake package simpler and closer to stock.
Why It Works
- Carbon-fiber-reinforced silicon-carbide ceramic rotors are baked at temperatures above 1700°C, holding a stable friction coefficient under hard, repeated braking rather than fading as heat builds.
- TTSPORT LCCB carbon-ceramic rotors weigh more than 50% less than comparable steel rotors, cutting unsprung mass and helping the suspension react faster.
- Thermal stability above 1300°C means the system resists fade during extended hard driving or track sessions, not just a single hard stop.
- Lower NVH and better corrosion resistance than a steel rotor of similar spec, so the discs hold up better in wet or harsh conditions without rusting or pitting.
- Built to bolt straight in with the front ten-piston and rear four-piston caliper package — no extra modification needed for install.
