Brake sizes

Hey Fasteddie07,
That's a trick question. Brake clearance is not typically something you can answer yes or no to without reference to a specific wheel and a specific brake package. Part of the problem is that when you talk about "bigger rims" you are speaking in unspecific terms. Wheels have a few key dimensions that determine the overall "size" of the wheel, and any of them can change more or less independent of the other (it's up to the manufacturer to determine this). These are typically: Diameter, Width, Offset (and Backspacing, a function of width and offset).
To make matters worse, brake clearance cannot be automatically determined from ANY of the above parameters I just spoke of. So, for example, you could have a set of GT500 rims at something like 18"x9.5" with +45mm offset that will obviously fit the Brembo brake package. Then you get another wheel of the exact same 18"x9.5" and +45mm offset and it won't clear the brakes. Why? Spoke design. Take a look at the GT500 rims and you see how wide they bow in the center. That's there to clear the very wide Brembo brakes.
So even if you have an 18x10" wheel with +35mm offset (don't think it would fit well, but this is just an example), you may still have interference. The same is true of a 19" or 20" wheel, etc., etc. The bottom line is that you need to have wheel in hand and either ask someone who has tried the exact same combination if it works, or you get a template (if available) to test on said wheel.
Speaking of asking those who have actually used the Brembo package, one of our own, eric6913, has fitted OEM 18"x8.5" Bullit wheels by using 1" (25mm) bolt-on style spacers. You can PM him and ask him about his experience if that's a route you might consider.
Best,
