Yeah, you were right.
[B"This upgrade uses stock calipers and pads. The rotors are changed to increase the diameter over an inch to 11.5 inch rotors. One very nice feature of this upgrade is that you can still use stock 15inch rims, but you will not be able to use 14 inch rims. This upgrade also does not affect the
track of the car either as it does not move the wheel in or out.
The key ingredient is the rotors which have the correct offset and thickness. They are off the rear of a 97 Firebird and can be bought at NAPA (Part # 4886407) for ~$25.00. These are slightly different than the stock Fierbird rotors in that they are thicker at the mounting surface, which makes them better than the OEM
Firebird rotors for this swap. They do need to have drilled for the Fiero bolt pattern (5 X 100). The hub centering hole is also larger than the Fiero's. This may be a difficult part for some without access to a lathe. You just need a collor that is the same inside diameter as the Fiero rotor and same outside diameter as the inside of the Fierbird rotor.
Then you need to build a bracket to place the caliper out on the rotor. What I did was get some 3/16 steel plate and drilled four holes. Two to bolt it to the hubs and two to bolt the calipers to. These two need threads on them so I tack welded a nut on the back side. I tack welded the nut on while the caliper was bolted on so that I knew that the nuts were in exactly the right spacing and straight. These adapter brackets need to rotate the caliper ~30 deg as the bolts will interfeer with each other if you don't. I also went to a nut and bolt shop and bought grade 10.2 bolts as these are important"[/B]

the missinformed cause more problems...
any exhaust shop won't touch any brake custom fabricaation with a 35.5" pole. in order to change to an f-body caliper you have to have a machine shop cut a piece of steel to support the weight of a stoping vehicle well over 10,000lbs of pressue in an emergency situation.
Grand-am front calipers and rotors on the rear of any pre 88 fiero, and stainless lines are the ONLY brakes mods anyone should perform. unless you've got the $3500 for the AP/Baer or Brembo 13" 6 piston set.

No no, you don't use the F body caliper, just the larger diameter rotor. To do this though, you have to remount the stock caliper a little higher for the extra clearence. Have you seen the $2000 "Ocelet" brake kit? Thats all they do, but the rotors are cross drilled.

BTW, thanks for correcting me. I hate it when I'm wrong and nobody tells me. ;)

Sorry, but none of the Fieros ever made had a lotus tuned suspension. It has been proven and even the guys (Hulki and Parki) who engineered and created the Fiero have said so at many many Fiero shows.
It is one of the few myths that still don't seem to want to go away, including the other bad myth that all Fieros caught on fire :disappoin
