A1-156 Girodisc 2pc 410mm Front Brake Rotors (replace OEM PCCB) (Garage Sale)

A1-156 Girodisc Two-Piece 410mm Front Brake Rotors (Discontinued Design) Discontinued New old stock rotor.  These have the straight grooves as images show, not the new curved grooves.  Final Sale, no returns or exchanges. This GiroDisc system is a 410mm two-piece steel rotor and aluminum hat combination, a direct-replacement upgrade for your car's OEM PCCB brakes1. The Girodisc A1-156 will bolt directly to your Porsche and work perfectly with your OEM calipers. There are two main reasons for replacing your PCCB: first, Girodisc rotors are designed to shed heat more effectively than the original rotors; second, the machined cast iron rotor rings are far more durable than the fragile PCCB rotors. This is critical when you're swapping wheels on-and-off the car for track days or racing. It's so easy to nick a carbon rotor and take a chunk out of it, rendering it useless. Pair these Girodisc rotors with Girodisc A2-156 rear rotors to maintain your factory brake bias and ABS efficiency. When
