Good luck finding rotors for the Fiero IFS Al. I put this IFS under my '38 Plymouth and found out I couldn't use the Boyd Coddington wheels with it so I had to go back to the ever popular Mustang II. I couldn't find rotors for the Fiero and they were too small to redrill to the 4 3/4" bolt pattern. I did find some adapters to fit them, but the wheels stuck out past the fenders with the adapters. You are right though, this is a great IFS. I believe this could be the frontend of the future if somebody would make some aftermarket parts for it. Maybe we could get together and make the parts and corner the market. Of course this was 5 years ago when I did this and parts may be available now. Good Luck!!!
