I know i have seen this, But i was wondering if someone has performed this before. I want to place the front disks and calipers in the rear. Yes i understand that this will eliminate the emergency brake, but this car is used for track purposes only.

 

What are you putting on the front?

This idea is completely useless unless you're going to a much bigger brake on the front.

 

Its not even the size of the brake rotor, but the surface area of the pistons vs the master cylinder. Balance would be way off unless you used a proportioning valve and a large MC.

 

Here's another alternative you might consider:

However, I am not sure of the availability of the brackets since it has been several years since I bought mine.
