ok so there a few things i wanna do i want to change my rear drum breaks in my 1991 firebird because there a pain to replace and there starting to rust. i wanna change them into disk breaks in the back but i cant fine a affordable kit... can i take the axles off and make some on my own for less then $400? and whats a good performance chip thats give me more hp and more mpg at the same time? gas is almost 5 dollars here.
