Those legend guys are running the Type II rotor (28mm 93-95 legend rotor) with NSX caliper and they arn't having any problems requiring shimming.

I got this in an email from a Legend guy that did the swap

"Hey man,
I installed GS spec rotors on my car, and the NSX calipers. The NSX calipers fit perfect because the NSX rotor and GS rotor are the same thickness. The pads are compatible along the line also. Good luck with your conversion.... Jason"
