I am on another automotive forum at First Integration. It's a forum for 1st generation Integra people. Someone on there started a GT3 challeng using a NSX Type R (fully modded, but no LM models and no cheats of any kind) running the best possible lap on Laguna Seca. Here's the thread from the fourm. I'm currently second with 1:16.805. I really didn't think that sub 1:18s were possible until I kept digging at it! I'm probably going to give it another shot later today when I get home.
