Anyone though about changing the rear 2 piston caliper to the same one as the front ? Wonder how much that will cost

 

no clue but im sure not cheap bc you;ll have to get the stock calipers from a dealer then have brackets made. I think your best bet is to just get a full aftermarket BBK.

 

brake bias will be completely off... will not be a good idea....

the G37 calipers are cheap...

anyone want to upgrade their non sport brakes to sport is about 2000 for Front & Rear clipers, rotors, pads! all new OEM parts...

The rear calipers are fine, any "upgrade" to 4 pot will just be for looks...

more pistons does not mean better performance... usually just more uniform pad wear thats about it...

4pot for the front, 2pot for the rear in my opinion is the best way to go... 6 pot up front but all you will get is a little better cooling, but even with a good 4 pot brake system, it will be hard to get the brakes to fade...

 

Agreed unless you are doing some serious track days you will not get the oem brakes hot enough to start fading...

 

The other thing to keep in mind is that the front brakes are used much more than the back brakes. They are not used equally at least on the cars I have owned. You always have to change out the front brakes but the back will still be good.
