Driving on cracked rotor
First of all, let this be a lesson to all of you because I have learned the hard way. DONT CHEAP OUT ON YOUR ROTORS. I purchased a set of drilled/slotted rotors from r1concepts on ebay about 8 months ago. The first set warped within two weeks, but the company replaced the rotors for me. The second set has been on my car since, and has gradually begun to warp.
My buddy and I decided to lower the car some more last night, and upon doing so I discovered that the driver front rotor has a crack about half way through it(meaning it starts at the top of the rotor but does not go all the way down to the hub) originating from one of the drilled holes. My question is- will it be ok to drive with the rotor like this until the new ones come in? The TL is my only car so I am out of transportation without it.

if its just a hair line crack id say if you had to it would be ok, Just take it easy. Odds are you have been driving on it like that for awhile. That is the problem with cross drilled rotors that weren't designed to be cross drilled.

This is what i was thinking as well, it is a hairline crack. Do these types of cracks spread fast or gradually?

Consider this: lets say that the rotor is turning as you're braking and the crack is advancing towards the brake pad. As this happens, everything is fine, as the crack is experiencing compression (trying to move forward into the brake pad, pad is pushing rotor back the other way, creating a compression zone in the rotor right above the pad). However, as the crack passes through the brake pad and comes out the other side, it now experiences a tension zone. This is the problem area - that tension area, due to the reverse of what I just described, will put huge amounts of stress on the non-cracked area.
See the picture below for a visual of what I'm talking about.

I debated on those. But I didnt see any logic in skimping on such a critical component. I went with EBC slotted and dimped and havent had any warping or cracking at all.
