For you it's not, for me it add's to the rest I do to my car to make it feel much more modern and enjoyable to drive and less of that 80's GM shitbox that all 80's GM vehicles feel like today compared to anything significantly newer than that.


I remember the old boys saying ' They sure don't make them like they used to' and to that I say ' Thank god for that!'

History, short version: Original 4 wheel GA "Upgrade" was first done by a Race Team on a "Trailer Queen" Race Car never driven on the street! That site went down soon after so others only "copied" the data & worse push it for street use that's Illegal in Most US States & many other Countries. Later someone added Seville rears but still has most of same problems but "restores" P-brake & Bias to the system. Then Someone Else thew in Big Booster to the "upgrade" mix that raises Line Pressure causing hydraulic problems, worse for "Panic Stopping" when Line Pressure can hit 1500psi or more w/ the Big Booster.

For many "fan boys" loving "GA upgrades," many did that or got sold a Fiero w/ that & had to remove this to drive that including TFS "upgrade" only follow same directions & never bother w/ other problems covered in cave & else where. For Years TFS didn't even bother to tell buyers that Big MC only applied to the "GA Upgrade" & was required not optional for any version of "GA Upgrade."

So many w/ OE setup were sold the Big MC by TFS, had huge problems, & still blamed GM for "Crap Fiero Brakes" never connecting the dots or Fixing/Restoring the brakes the right way & maybe using better pads like Wagner TQ pads but Not "Race Pads" that often have other problems because never get hot enough to work on the street.
Many get sold w/ same Hype pushing Big Booster that often Hinds a lot of Brake problems.

I race a Fiero and I have Grand Am rotors all round. Grand Am calipers up front, Seville calipers on the rear. I have the S10 brake booster as well with a slightly bigger master cylinder.
The master cylinder: I don't remember what it came off? But it's physically identical to the original aluminium one, bit it's made of cast iron. (Bigger bore and piston of course.)

So to answer the question: No my brakes are not over powered compaired to original. However, I don't get as much brake fade or brake disc/rotor overheating.
The pedal feels pretty much as original. I can, and have locked up the brakes on a trackday, but everything is under control. No rear lockup before front, no spin outs!

My opinion: Grand Am rotors just reduce the brake fade and overheating on a circuit. Doesn't make much difference for normal everyday driving.

Not only that & other issues w/ the GA Front... Seville rear calipers has Same Piston Design & Problems as Fiero & others that should have same Recall but Cadillac Almost never got Stick Trans so Owners never got a Recall Notice for this problem.

GM Brake Recall w/ NHTSA "blessing" to save GM Big Money only recall stick cars only because Auto Trans cars have Park Pawl in then to hold a car when parked. Yet all have same problem that P-brake doesn't work + bad Pistons also effect Service Brake causing Low Pedal to Dragging Pads causing a Brake Failure or even Fires.
Huge Numbers of NHTSA Recalls allow Makers to do the Absolute Minimum for "fixing" the problem like Kia/Hyundai "reprogramming" the ECM to "Fix" crap motors w/ similar problems w/ Fiero V6 w/ crank death or even engine blows at highway speeds.
