Brake Issues

There's also a 10% off code I found here. Those brakes are going to be loud, it's normal. I am getting the stillen front bumper and cooling ducts installed "soon". You can try RBF660 but be mindful it has a much higher tendency to suck up water from the air. Also you might want to get a basic brake fluid tester or just change the fluid prior to every event. Can't think of anything else you could try.

The Stillen brake duct does not provide enough air volume to cool the rotors and calipers, the ducting is two inches. I have a friend who fabricated 3 inch ducts which apparently provided a lot more cooling (dropped the peak temp by 150F). The two piece rotor provides additional cooling.

Anyone have any experience with carbon ceramic rotors? I know they're expensive, but I'm not sure if that's a solution.
