Porsche 380mm Front Rotors
Experience the difference precision-engineered braking makes with Girodisc 380mm two-piece floating front rotors for Porsche. Designed for direct bolt-on fitment, these rotors deliver superior cooling efficiency, reduced weight, and improved pedal modulation under repeated high-performance use.
Precision-Machined for Porsche Performance
The Girodisc 380mm rotor is built to handle the demands of aggressive street driving and track sessions alike. Utilizing a floating mount system, each rotor allows controlled movement between the hat and disc—reducing stress, minimizing warping, and improving thermal expansion control. This results in smoother, quieter, and more consistent braking performance in all conditions.

Porsche 380mm Front Rotor FAQs:
Are these rotors compatible with factory center-lock hubs? Yes. If your Porsche uses OEM center-lock wheels, select the center-lock drive pin option during purchase.
Do these improve braking performance? Yes. The floating design and advanced metallurgy offer better heat control and fade resistance than standard rotors.
Can I use stock brake pads? Yes, factory pad fitment is retained, but upgraded compounds are recommended for track use.
Do these rotors require maintenance? Only normal inspection for wear; replacement rings are available separately to reuse your existing hats.
For Porsche enthusiasts demanding the ultimate in braking consistency and cooling, Girodisc rotors deliver unmatched engineering and reliability—ready for the street or the circuit.
