I am a 2014 boosted 3.8 and I have the Brembo Big Brake kit on my fronts and OE Brembo on rears (no real reason to spend the money for the rears). I have 19" Volk G50 rims and no clearance issues. The kit is not cheap.
I have the OEM rims and it won't work with the Brembo big brake kits. I just did get some 19" rims for my summer tires but dont want to change my winter rims and tires just yet.
