The ONLY other thing it can be is those JUNK OEM rotors that were put on the SRTs. I'm doing some research now as I'm embarrassed having my setup that I dropped over 5K on (Brembos/Rotors/OEM SRT Wheels & tires) squeal at every stoplight, etc.
Don't get me wrong they really make the WK2 but still...
Anyways, if anyone knows of any compatible slotted/driller rotors that would eliminate this problem I'm all ears. (Or perhaps someone can confirm that they had the same problems - Scottina??? ) We were two of only a few guys on here who did this work...please let me know.
Yes, pad material can affect squeal as well as the fitting of backing plates/shims on the pads and attention to using lubrication on contact/moving surfaces. Run Brembos on my wife's 350Z and on another competition car with race pads and no squeal whatsoever. As mentioned above by Scottina86, brake bedding in can have a big impact as if this isn't done the pads will develop a hard glaze which will reduce performance, increase rotor wear and squeal like hell! Might need to go out and give the brakes a hard workout to clear the glazing off the pads.
Check out PAGID Racing
which gives some info on bedding brakes by Pagid but same should apply to most brakes. The rotors wont be the source of the problem, that's for sure.
