Give me some time. I've only got 1k miles.

Peter,
Checked mine when I washed it this afternoon. Slight concentric discoloration but no real grooving. I suspect you will find that the shallow trenches are located in the same location as the cross drilling of the discs.

Thanks for the feedback guys... I had the car in for 15k service this past week and they checked the amount of brake pad that was left and didn't mention anything about the rotors. Of course that doesn't mean much...

Pat, I had my car dyno'ed at Hennessey Performance Engineering originally and in order to maintain as much consistency as possible I'm going to go back there to re-dyno.

someone at the lexus dealership told me the other day that we CAN resurface the rotors as long as they dont have a lip. i wish i would have known that a few months ago. mine have a lip now

Like all vehicles, the rotors should have a minimum thickness spec on them. As long as the rotors exceed that spec, you can turn them. There is no reason to replace the rotor every time the brakes need to be done. I will say I've never done the brakes on the ISF, but I've done brakes on tons of other cars including the Z06 I used to have and I dont see why the ISF will be any different.
The lip doesnt matter as it will be cut off when the rotor is turned. Every car gets this lip.

Came across this today...
Just thought I'd post something for all the drilled disc champions out there. Here's what Lexus says in our Factory Service Manual about the drilled discs (I've never seen this for undrilled discs anywhere):
