I've been compiling everything I would like to do to my 17 Challenger and par for the course my particular tastes are next to all novel for this car. It seems like you lose about 9 ft of distance when braking from 60 with the 4 piston brembos, or baer I don't care. I'm just really wanting to make this car my own and was wondering what you wiser and more knowledgeable gentlemen have to say about the idea of putting 4 piston calipers on the front to fit 18s up there. Thanks! Cheers.
