Brake Issues

By nasty marks I am assuming you mean you have hot spots on your rotors. Unless your getting vibrations I wouldn't bother changing them. I got them before and they went away after some normal driving. Now I used Frozenrotors and they seem to be holding up much better and they are not much more then OEM blanks. 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.

:/ I did upgrade the rotors, the fronts are the Z1 2 piece slotted rotors, they're holding much better than the rear slotted z1 performance rotors but still bunch of hot spots, and rebedding them on the highway helped a little bit but not too much.

Probably going to look at custom brake ducts or something for my bumper, thanks for the suggestions though

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.

You also don't want to over cool as well as track pads do need some heat in them to work properly! You may need a more aggressive pad or a bbk as well as going to a 3" hose.
