On my 07 with the front Brembo swap, if we put too much bite in the rear pads, it would just prematurely try to invoke the ABS. I think this would be from a combination of the front bite leading to enough brake dive to unload the rear sufficiently to make those tires light on the road. It just had FRPP springs and Bilsteins, so with more spring & shock you could get more aggressive with the rear pads too I'd guess. If the car doesn't have Brembos up front, it may not be as much of an issue.

And yes, the TC will engage the rear brakes heavily on a tight course like TMP trying to tame the wheelspin out of corners. You need to turn that off or constantly be changing rear brake components. Cooling for the front brakes is a good idea too.
