Drilled and Slotted Rotors
From what I understand, drilled rotors can crack under extreme braking thus not making those worthy for the track. Is that correct? Are those rotors all right for a daily driver that doesn't see much hard braking? I was asking because there seems to be some really awesome deals on ebay. Any information would be greatly appreciated.

Depends on how aggressive you get and what brand you get.
If you get the rotors with holes CAST into them, like the expensive Baer or Brembo setups, they wont crack.
If you buy a no-name brand, they may warp or crack in consistent hard braking. If you had them cryo-treated, you might get around that problem.

The cheap end rotors that are drilled after the rotor is cast are the one that are subject to radial cracks around the holes. Extreme braking at very high speeds like you can see on a road coruse generates a tremendous amount of heat in the rotor and that leads to cracking at the weak points around the holes.
If you want drilled/slotted rotors for looks and you are doing street driving, they should be fine. If you want true extreme braking performance with a drilled rotor, expect to pay some serious bucks for them. Baer, Eridaspeed, and Wildwood make excellent rotors that will withstand extreme heat.

I bought rotors from iRotors.com. they were around $250 for all four, i havent seen any cracking since ive gottin them about 10k miles ago, and i have had my brakes literally smoking from hard breaking.
But i have seen people complain about cracking with these rotors, amybe i just got lucky. but under daily driving they should be fine.

I just had a thread on these rotors within the past month. If you want to stay on the inexpensive side and they're for general street use "for looks" then its recommended that you get the dimple and slotted rotors. They give you the drilled look but they are only partially drilled. (no cracks). just my .02

Several people have mentioned the Baer Eradispeeds. What are the advantages of the two piece rotors for a street driven car? I know the two piece rotors are lighter and probably look better, but are there any other reasons why they're better than the one piece? Any reason the one piece rotors aren't good? How do the one piece rotors compare with other manufacturers like Brembo or Powerslot?
I certainly like the two piece rotors, but they're quite pricey and I wonder if they're worth the $300+ extra over the cost of the one piece rotors.

The fact that they are lighter is the main reason, reducing the unsprung weight on the suspension really improves how the car handles.

Otherwise, I have no doubt that these will at minimum endure as well as OEM, if not better, due to improved heat dissipation
