They come in 18x8.5 and 18x9.5,and also 19's..There are 3 finishes,a chrome,silver(like the picture),and a grey center with polished lip.My set was $1100 shipped through Autobahn wheels(I highly recommend them).I got 18's up front and 19's in the rear.I am not sure about the big brake kit..Depends on how it is designed.I do know that my stock calipers barely clear.There is about a 2 credit card space in between..
