I don't really see how brembo calipers would help stop 8.5" wide wheels any better. It's almost an oxymoron... just saying...
I think more people buy Brembos and other big brakes for the looks than because they really need the performance. The stock brakes will stop the car once or twice just as well as any big brake kit; the big brakes really only make a difference with multiple stops and dealing with the resulting heat.
But that's cool, each to his own, looks is just a good a reason as any to buy them.
