I don't think so.

You'll need spacers to clear the bigger calipers. It's a fairy easy DIY job. It's direct swap.

Caliper clearance for aftermarket wheels are on a case by case basis totally dependent on the wheel design. It will not clear stock wheels because the spokes are already too close to the calipars.

Unfortunately, I don't know the exact difference of the thickness between stock and TT calipers otherwise, that would at least be more information to work with. Your best to see if aftermarket wheels will clear is to take a look at the clearance of the current calipers. If you have about .5 to 1 inch clearance now, then there is a good possibility the wheels will clear the TT calipers because I don't think they are more than .75 inches thicker than stock...Hope this helps.

Right Brent, to be sure you will have clearance on new rims, make sure that you specify the SupraTT "Hi-disc" fitment and offset when ordering. You will get the same rim that a SupraTT owner would use........
As for stock rims, a 15mm spacer should get you plenty of clearance....call Dave at www.gtautosports.com for a pair...
I currently have a +35 offset on my front wheels, also, the spoke is curved outward slightly. I have about 2 whole inches of clearance with stock calipers, so I should have plenty of clearance for the SupraTT brakes...
