Porsche 911 Carrera Big Brake Kit Upgrade / TTSPORT Dacromet Rotor
As driver-assist systems take on more of the braking workload, the brakes underneath have to keep up. On this Porsche 911 Carrera, the stock front four-piston/rear two-piston setup felt underwhelming for the platform, so the owner — working with installer Jieao Vehicles — moved to factory-upgraded Brembo calipers paired with TTSPORT high-carbon heat-treated rotors, front and rear.
The upgrade path here is OEM-plus: keep the Brembo caliper architecture Porsche already engineers for this chassis, but step up to the higher-spec six-piston front and four-piston rear units, then pair them with TTSPORT's 405mm front and 380mm rear high-carbon heat-treated rotors for the added mass and heat capacity a bigger caliper can actually use.

Why It Works
Going from front four-piston/rear two-piston to front six-piston/rear four-piston calipers spreads clamping force across more pad area, which generally means better modulation and less pedal travel before bite. But a bigger caliper only pays off if the rotor behind it can absorb and shed the extra heat — that's where the TTSPORT discs come in.
TTSPORT builds these high-carbon heat-treated rotors to pair with a range of aftermarket and factory-upgrade calipers, for street driving, mountain roads, autocross, and general track days alike.
- High-carbon heat treatment raises the rotor's resistance to heat-cycle fatigue, improves wear resistance, and cuts brake noise.
- A Dacromet coating resists corrosion and helps keep the friction coefficient between pad and rotor consistent over time.
- Drilled, curved, or slotted rotor faces vent brake dust and gas so the pad keeps even contact, while adding surface area for airflow-driven cooling.
- Confirmed fitment behind 21-inch wheels and up, with no reported spacer or clearance issues in this build.
