Default Rotors developing cracks...

Over the past few weeks, there is an intermittent squeaking/chirping noise coming from the front end of my car. It doesn't happen all the time, only once in a while. Well today I decided to go see if I can find the culprit of the problem. Took my front wheels off to see if anything was rubbing and what not. As I looked at my rotors, I noticed they were starting to develop tiny cracks in them, and the passenger side is much worse than the driver side. I'm pretty sure its time for new rotors because I know the cracks are going to get bigger over time. What would you guys suggest? I'm not looking at doing the cobra brake conversion because I was planning on buying slicks and skinnies for the track in the summer to try and get some traction with my 4.30's.

PS - Anyone have any suggestions on what the noise I first described could be?

Sounds like you rotors where over heating.
I would suggest a slotted and drilled rotors.
Brand name? maybe someone can shed that to you.




Good luck

Drilled rotors are prone to cracks, and are not needed with modern pads...

Here's a great white paper report about driled and slotted rotors...

Just replace them with new blank rotors. The Cobra/Mach/Bullitt upgrade is great but not if you plan on running skinnies.

Brembo Blanks FTW!
Unfortunately Cross drilled fall into the Ricer/Import category for me. Yes they might look cool and give the illusion of speed but serve no real function. Just my .02

I was looking and found a set of Brembo OEM replacement rotors for 120 bucks. Sound like a good deal?

Here is something to add to Cliffs post. This is from the Tire Rack website
Brake Rotors and Track Use

"Slotted, drilled or dimpled rotors offered as OEM replacements should not be considered appropriate for high-speed track use.

While grooved, drilled and slotted rotors offer an enhanced appearance and add some resistance to the boundary layer of gasses that can build up between the pad and rotor, they are not designed to withstand the extreme temperatures that are produced on the racetrack. If they are used on the track, it is very important that the rotors be carefully inspected and should not be driven on if even minor signs of deterioration are seen. Note, too, that if these products are used on the track they are not warrantable."
