oversized piston calipers, are they worth it?

In my opinion, if you want to stop better, you will get more from a larger rotor than 'just' a larger caliper. I run b body spindles,caliper with 12" Camaro rotors. It stops better than any vehicle I own. I do however run 11"(maybe 10") disks on the rear as well.

the 12" rotor set up you have uses the same caliper and pads that is used on the 11" camaro set up
