The tang on the spindle that faces the back of the rotor has to be ground for clearance of the thicker GA rotor. I used 91 rotors, calipers and pads on my 4 wheel conversion. If you do the back brakes, too, it just bolts right up. Remember that the bleeder screw has to be on top of the caliper and you'll do fine.
Do the new brackets replace the fiero ones? or u bolt the new bracket to the fiero bracket? Im trying to remember by memory so forgive me if im WAY OFF lol
yes, they replace the existing Fiero brackets. the kit also comes with new bearings & grease seals for the hub. you will have to get the existing Fiero rotor cut down to just a hub, and also replace the lugs with longer ones, so you can put on the vented rotor

If you take your existing front Fiero rotor to a machine shop they can turn off the rotor, just leaving a hub.
Im not worried about the hub, I have a laythe/mill here to do that, I just wanted to know if the caliper was a bolt on, as I have 04 calipers that are slightly to long to fit both mounting holes, so I was hoping the older calipers would be a direct bolt in on the front.

GM started using Anti-Lock brakes on 91 Grand Ams and 92 Berettas. Those calipers and rotors are different. You need to use 85-91Beratta, Cavalier calipers, or 85-90 Grand Am Calipers. Those are the ones that match the mounts on the Fiero. The brackets still have to be shaved on the front, and you may have to bend the dust plate back a little. I've done this on my rear wheels and plan to do the front after I get my other Fiero running.

these are 86-91 Beratta and 85-90 Grand Am parts
