A little, but the real advantage comes when the leading piston is smaller than the trailing piston to better distribute force over the entire pad.

There is another option as well (Wilwood High Performance Disc Brakes - 1975 Chevrolet Camaro - Front Brake Kit No.: 140-10738), which is the 6-piston kit with 7.3 sq-in per pad.

Still smaller than the GM, at 9.5 sqin.

For (2), I think the offset is -0.28, not 0.28, so it is about 1/4" in, which should provide more wheel clearance. For (3), I was under the impression that you use a stock spindle, which should accommodate these kits. I must be wrong there. Thanks again.

You might be right, but I've seen the drawing of what I suspect is the hub that they use. The wheel mounting face is moved out. I will check to see whether there's a different part though. It would be a big help for other applications.
