You could go with Sunbird GT front brakes and not have to cut or grind anything. Of course, you will still need the hubs machined, but no other modifications. |

The next question is, how does the piston diameter compare to the Grand Am.

I didn't think to check. Basically, they are the Fiero brakes, only vented.

google =www.fierosails.com
go to fiero secretes
read brake upgrade ,grand am
brake conversion using berretta parts,by randy agee
fiero sails has a full 1/2 day of fiero reading INVESTIGATE..OH JOY
to improve Fiero brakes use top quality pads ,,people go with lowest price!! a no no with Fiero brake pads
using wagner thermo quiets on the front will improve your brakes or fiero store carbomet
the problem with most Fiero brakes is the owner purchased lowest price
ebc,hawk & many others work ,,but the thermoquiets are an all around quality pad,,good to see many fiero owners now run these on thier other cars

uhlanstan, I read that post while doing my own research. I found it hard to follow and even harder to read.
Here is a link to that page for those of you that want to check it out.
This thread is for information on the grand am brake upgrade. I don't want it to turn into an argument about whether its better than any of the other types of upgrade. Everyone has their reasons for doing, or not doing, this upgrade. This is just a place for the people that want to do it to come and get the specifics about how to do it.

I know this is an old thread but I had a question about this.
What keeps the new rotor centered on the old hub once its installed? If the outer diameter of the hub isn't matched exactly to the new disc, can it be misaligned?

More than likely you will need to find some centering rings that fit between the hub and the rotor.
I found some on eBay that worked. However, they are plastic and not that durable. I may look into getting some
metal rings but that may require getting the rotor ID bored out to fit.
Here's the link for the seller I bought them from:

If I remember correctly, the old hub-centering for the fiero wheel matches the hub bore on the grand am rotors. I no longer have the vehicle so I can't check, but the pictures look to be a pretty tight fit. However, it does look like most of the wheel centering was lost to the thickness of the added rotor.
Hope this helps,
Phil
