Has this been done or even possible to fit the front Brembo brakes on the rear as an alternative to buying a BBK for the rear when somebody buys the front?

 

the bias will be all messed up. i would say thats pretty unsafe

 

It won't fit, the brackets don't lineup.

 

If one were to fabricate some custom brackets would it be possible to make it work? Alang35 said the bias would be messed up but i dont see the difference in rear BBK's except that all the hardware that come with them are made for the rear so why wouldn't somebody be able to fabricate customer hardware to retrofit the fronts on the rear?

 

uhhhhhhhhhhhhhhhhh lol..

 

I think you should do some more research on BBK's.

The front piston sizes on the factory BREMBO caliper will have way too much torque output for the rear axles. Fabricating a bracket to make it fit wouldn't be a problem but what would you run in the front? You would need some serious brakes in the front to match the brake bias of putting the BREMBO caliper in the rear which is way too much braking force thats needed for the Z.

 

of course your brake biased will be jacked. the area of the pad will tell you that.

 

I guess I should have been a little more clear with what I had in mind. My question was answered that yes it's possible to fit the front Brembos on the rear and so far the biggest BBK for the front is the Rotora 8-piston correct me if I'm wrong?

 

rotora has 12-piston

 

Even better...thank you gentlemen my question has been answered.

 

So you would run a Rotora 8 piston front and a BREMBO 4 piston rear? Just because you're running a 8 piston caliper doesn't mean that the bias will be balanced. Take a look at Rotora's 6 piston caliper compared to a STOPTECH 4 piston ST40 caliper. The ST40 caliper is almost similar in size to the Rotora 6 piston, why?. STOPTECH's ST40 caliper consists of bigger piston sizes compensating for the size difference of the caliper. Its the piston sizes that makes a difference in the torque output of the caliper. If you're serious on dropping some cash on this custom setup, I'd research to see exactly what torque output rating the front caliper will have compared to the BREMBO 4 piston that you want to use on the rear. If you don't really care about the brake bias and the balance of your braking system, than this custom setup can be done. Have a machine shop fabricate you a caliper bracket for the rear and I'm sure you can piece all the hardware together.

Why not just get a BBK that runs a 4 piston rear caliper? The costs of making this custom brake setup to work properly will probably cost more than just buying a 4 wheel BBK.

 

Research goes a long way these days. lol

 

I had a chance to look at some of the numbers involved with this. As a start, the front calipers have about 50% greater torque output than the rear calipers which is a significant amount. Going from a mellow street pad to a very aggressive track pad is about a 5% shift so these are huge numbers. In order to maintain balance with the front brake system on the rear of the car, you would need to increase front brake torque by double and that basically means maxing out the piston sizing on our 6 piston caliper or trying to mount 2 stock front calipers onto the front rotor.

After all this work, custom parts, and engineering, what do you get?

1: A super long soft brake pedal that is very grabby with the only fix being a new VERY large master cylinder

2: A completely useless ABS and VDC system because the computer cant adjust to such a drastic change.

3: No parking brake since the front rotors wont clear that setup.

4: Basically the same balance as stock so no improvement in stopping distances

5: Zero increase in front heat capacity since the rotor size has not increased and only an incremental increase in rear heat capacity which isnt even an issue on the factory Brembo setup to start with.

So the easy answer is no, dont do it, its not worth it. There are plenty of cheaper, easier and better options out there, many of which we already offer

 

Good stuff, it's nice to have vendors like Stoptech on the boards.

 

yep, companies like stoptech pour a lot of money into testing and making sure everything works together safely. why would you attempt to do this on your own resulting in something expensive and unsafe?

 

listen to this advice.. its very sound.. but then.. your the one with the money..

 

The first post had the correct answer, "the bias will be all messed up" then Stoptech validates this with a complete accurate description of what you would have. You need to install a system or leave it alone.
