The total heat generated is a constant that comes from how much kinetic energy you take out of the moving car. Bigger parts, of course, allow more room for the heat energy to spread out in, so the temperature is lower.

Tboner,
The E0's had a larger pad along with the larger rotor. E1's used the larger rotor with the same pad as the other cars. I know it's not that clearcut, and that there was some part swapping, but that's the general idea.

I don't believe the size of the pad is that different. Peep these pics of both the E0 and the standard pads They are cut from the BAT catalog. By looking at the scale drawings, I'm not convinced the E0 pads have more surface area than do the E1 pads. The E0 pads extend closer to the rotor hat compared to the E1 pads, but the bottom portion is much more narrow in comparison to the top, and the arc of the pad is smaller than the E1 pad. I'm not convinced there is much difference in the surface area.  TB

Well I can tell you from experience, when my pads on my E0 went south, and AZ didn't have any replacements, I installed some E1 pads (had to notch the "ears" slightly but they fit right on) and they only contacted say 60% of the rotor. I drove around for a week like that (waiting for the right pads to come in) and the bottom 40% was all nasty and rusty by weeks end. There is a size difference...

He's talking about total area of the pad, not the width of the sweep.
And looking at the pictures, I agree that there doesn't appear to be much difference. The E0 pad is not just the same shape as the E1, but taller. It is a completely different shape. Anyone know how to calculate the area of a blob?
Here's a point to ponder. What about effective brake radius?

You have to determine if the drawings are to scale first. If they are to scale, then you can just use normal geometric shapes to fit in the area to get a good idea of the size. Easiest way is probably the 'strip' method where you use a 1 cm wide strip and measure the length of it as you lay it on the drawing sequentially from left to right while being sure not to leave any gaps.
There are other mathematical solutions since it appears to be a piece cut out of a washer shape (i.e. piece of an arc).

Those are the actual sizes. I believe that the surface area is about the same but the swept area of the newer pads is greater making them more efficient in theory. The bigger problem will be getting pads for the early SVT calipers as many people don't make them.
MC,
You are nuts for trying to use the wrong pads. The calipers are competely different and aren't designe to use the other ones pads.

I know..I only used them for a week. Like you said..getting the earlier size can take time sometimes! But with a little grinding on the ears..they fit right in. So how can they have more swept area?

Seems to me that if they are the same size, they will have the same swept area.
It appears, though, the the effective brake radius on the newer pads is a full 1/8th of an inch bigger!
