Anyone tried the oversized single piston caliper?
Jegs has a brake caliper in there catolog, by US Brake. It is a replacement for the single piston metric caliper which is stock on most our cars. It has a 2 3/4" piston, instead of the stock 2 1/2" piston. They say it gives you 20% more force. For the price it seems like a decent upgrade.
Worth it? I think they were 80 bucks each.

I briefly looked into it, but dropped it.
Doesn't increase the radius of the rotor, which doesn't give it a longer moment or more rotor surface to work on. Doesn't increase the size of the pad material surface.
More force on the same diameter rotor with the same size pads just meant I could overheat my pads quicker...didn't solve a problem for me, so I went 1LE.

Don't even waste your time looking.
Besides what Kevin mentioned, most F-bodies lack rear brake bias to begin with, so increasing the piston area up front would only make things worse.
Of course, you could also make a corresponding change to the rear calipers, to increase piston area in the back. But, I doubt you'll find that to be quite as easy. And, even if you did, you'd still end up with no more thermal capacity than when you started, so although you'd have a reduction in pedal effort, your brakes would overheat just as fast as before.
