I don't have a shop manual, so this is just a random thought...

Would it work to move the front brakes and rotors to the rear?

Think about this: buy a really nice upgraded six-piston brake kit for the front only. But then move the existing front brake pieces to the rear.

Would they fit? Seems like a good ghetto way to get some decent upgraded braking power (for non-Brembos) without paying a ton.

 

If I remenber correctly the front mounts with a 22mm bolt, and the rear with a 19mm, so without an adapter it would not work.

It also may not be too balanced, and the master cylinder may not be sized properly....

 

Bump for a really good question.

 

They need to be balanced in terms of braking force - too much in the back will lock up as the weight transfers forward. This is bad.

Also, unless you are racing or competing on a track, the extra brake is really overkill, but the cool factor may be worth something. You might try to paint the brake caliper assembly a cool color to match or contrast- just clean it well with brake cleaner spray first, then paint with a high temperature paint- it will look fine unless you get a lot of brake fluid on it.
If you have the $$, pull the caliper, and disassemble, and take it to a Jet-Hot place (or other coating company) and have them powder coat them for more robust color. Make sure that the powder coat stuff does not get into the bores for the pistons.

 

This will not work AT ALL. Take a good look at the rear rotors. See the BIG hub? The hub of the rear rotor incorporates the the parking brake which is a small drum brake.
