11" Brakes - is it worth it?

[StealthRider]

I want to upgrade my brakes on my 87 GN and really would like to keep my stock 87 GN wheels. Is it really a waste of money to use 11" B-body brakes? From what I read it seems like they are no different than stock GN brakes. If it is no different I will probably go to the 12" B-body brakes. If I do go to the 12" brakes how much backspacing will I need for 17x9 or 18x9 up front?
