I`ve heard of too much trouble with "some" kits *) ,so you need to get the right one if you buy new... *)stay away from SSB brakes...
But I hear lots of the cars in the same category , F bodies had same set up and disc optons...mine came with disc option.,..but like Novas etc...I hear the cheapest way is to get a used set from a junk yard then re-build it...the dics and pads are readily available ,you just need the spindles and the base set up...someone will chime in and tell you which cars to get it from...in the mean time I might get my friend Andy to tell you baout his set up...I think he`s got Baer , nice stuff ,but i think expensive...
