I've never had to rebuild my calipers so, I haven't heard of Lone Star Calipers. I have the GS Calipers which are Black with the Corvette Lettering on the side of the caliper.

I just mentioned it because that's what I have. Since you're staying with the 12" JL9 calipers, you don't need to worry about it.

Not actually but they do share the same pad surface area, the rotor dimension is larger in both diameter and thickness so that would seem to indicate yes BUT the calipers are more substantial and don't flex so it's actually substantially a better braking experience than that with the 12" rotors. The braking surface is also moved to a larger diameter of the rotor mass. The clamping force I guess you would say is substantially greater with the J55. Way more than heat transfer. Seldom ever mentioned but "tires" have a substantial effect on the braking experience, braking is actually quite sophisticated.
