Uh, ft/inches is length/length. I don't care who used it, it's not a unit of force. Probably a typo, but whatever. Just because it's in a magazine doesn't mean much. Inch-Lbs is what you're talking about.
Interesting. I was always looking at the '98's or so and not the later ones.
Some of what I based my info on was the old Baer kit that used the same calipers. Don't remember the name (Sport?) other than they called the calipers PGC "Pad Guided Calipers" (I think) because the pad actually clips into the caliper. The next step up was their GT kit with PDC "Pin Driven Calipers" and was basically the C5/6 caliper. Either way, pretty sure they listed the Cobra calipers as 38mm and I didn't see others so I thought they all were. Looks like the '99+ used a bigger piston in the Cobra calipers.
