hey i thought about this the other day...
can i throw my rotors n brakes from the front in the back???? anyone attepted this before???
*cause the front brakes are much bigger
I'm sure the rotors would probably fit, but you'll have issues trying to come up with a system of mounting the calipers. I bet the front calipers also use more fluid volume as well, so you may run into issues using them in the rear, probably needing a different master cylinder and proportioning valve. Would be a cool project though, since you're planning on doing an upgrade all the way around. Might be a cheap alternative to going with something like a Baer or Brembo setup if you find a way to make it work.
i do believe that someone makes a kit to put cobra front calipers in the rear. they did it on Horsepower TV when they installed 14in 4 pistons on the front.... the car stopped from 60 in like 90 something feet
