does it matter if the rear disc is and inch bigger then the front
i was looking at the wilwood street setup and the front is 10 3/4
andthe back is 12 inch   they are all 4 piston
will it make the back lock up or will it be ok

thanks aaron

Well, let's take a look at something here that your really need to consider.    Why would you put smaller brakes on the front than the back when the front brakes do the majority of your breaking force.   If you can, in my opinion, should have at least the same size or bigger brakes on the front.  Just my opinion from understanding how brakes work on cars...

I agree w/Charger74. But if you go bigger up front maybe an adjustable proportioning valve may help?
