Old thread, but wanted to add my two cents. It seems like you can no longer get the Grand Am brake upgrade. They used to sell a kit on the Fiero Store, and this is what I purchased years ago and installed on my Fiero:
I've never used them, as this is literally how it sits right now in a storage unit where it's been ... basically since the date on this picture (essentially, about 13 years), lol.
The reason WHY I got them though, was that I had really significant overheating problems with my 87 Fiero SE / V6. So, the last time I routinely used my Fiero was in the late 90s and early 2000s. It's largely been in various states of disrepair since then as I went on with life. But during that time, I was in my late teens and early 20s, and I drove like an irresponsible version of someone that age would. By the time I got home, my brakes would be
literally smoking in the front.
I had a relatively stock V6, with a bunch of general upgrades (exhuast, port matching, throttle body, blah blah). So maybe a solid 150hp.
I went through about three sets of rotors from 1996-1999, where they would often warp. It got to the point too where sometimes they would glaze over when hot, and I almost couldn't even stop... like my stopping distance increased two-fold. It was really, really bad. Like at one point, I'd have both feet on the brake trying to get it to stop and the car would casually roll to a stop the brakes had so much brake fade.
Then I switched to cross-drilled rotors (not vented). The Fiero Store offered these a while back, they had literally commissioned someone (if I remember correctly) to take factory stock rotors (AC Delco or whatever it was), and had them cross drilled per the specific side. After this, IMMEDIATELY all of my problems went away. I never had brake fade again, ever again. Note, they never made vented rotors because the rotors simply aren't thick enough to support a vented option with these brake calipers.
There are plenty of aftermarket kits now on the internet that offer cross-drilled rotors (not vented), and for nearly any application that doesn't involved a significant motor swap, you should be just fine swapping out the front rotors with cross-drilled.
EDIT to say, I ended up switching to the Grand Am brakes when I started restoring my car, but I haven't yet put it back on the street... so I can't say how good they are. I also replaced the brake booster with the one from the Chevy S-10. I did not have to beat on the frame with a hammer. It just fit.
