Front 4 Piston Calipers on rear rotors.
 

Hey guys. I was wondering if anyone new a simple way to put the 4 piston front calipers on the rear rotors. What am I going to have to do? And so forth. Do I need new rotors? Or can I just place another set of calipers on the rear? I've done some research and couldn't really find much. Thanks.

Don't do it. There is a reason your search found nothing.

There is much more involved than just bolting up the hardware.

It's not that I need the extra braking. I just like the symmetrical look of it. I just didn't know if it would even be worth my time or not.

you would have too much brake bias in the rear, this would severely offset the brake balance and it would actually take longer to stop, or be very dangerous. You can change this with a bias valve on the brake lines, but at that point you will be at the same pressure amount as the stock pieces. So no this is not worth the time to make a custom mount for no gain at all.

One of the talented Euro guys (higgi?) did just this very thing.
Of course, it was after putting something much larger on the front first.
I believe there was even talk of selling the adaptors but don't know what came of it.

It's not worth your time, especially not for symmetry's sake.

if you've ever driven a go-kart youd understand why rear brake bias that extreme is a bad thing. they only have brakes in the rear. makes the car undrivably tail happy.

I understand the idea of symmetricallity but youd need an adjustable brake proportioning valve set all the way to "FRONT" the entire time.

All good advice.

Basically, when you brake, all the weight shifts forward (simple explanation but it's more complex than that lol). So you always want less braking in the rear, so you don't lock up your rear too easily. So if you had bigger brakes in the front, then you could go bigger with the rears. But for symmetry, not worth it. And besides, you'd want a bigger caliper that included a parking brake mechanism, ideally.

aaaaaaaaaaaaaaaaand you would need to fabricate a parking brake set up, usually another small caliper


not sure what this symmetry stuff is, all cars have larger front calipers than the rears

If this really bothers you they make brake dust covers that look like a caliper and rotor. Just saying

I like the symmetrical look of Jennifer Anniston's Boobs..but I'm not getting a set.
I don't need them and it wouldn't be worth my time either.

If you need a brake set up like setup like that then you must have a Mean engine bay...or are driving in stop and go traffic on the Autobahn.
