This XR GT setup is still bit of WIP, it is intended for racing against Gtis at BL1 and for race lengths of 1-2 hours with 10% fuel only (team endurance rules).
Main goal was to get car handle, second goal was that car handles well trought whole race without tire changes, third goal was to be fast.
I have done 1.34.72 in not so perfect lap with it, but it should be possible to go lot faster, I'm not alien, just average if even that.
Would be interesting to hear how others will find it to fit their driving style.
