Hi guys, I'm saving up for the FGT, so I am currently grinding the Indy superspeedway in my ZR1 (RM) '09

The best lap I can get out of it is 44.8 seconds, does anyone have a better setup? I am sure this car can do it a few seconds quicker, I can 39.9 in my Minolta, but this is the American event (more cash).

Any tips would be great :-) thanks.
