J-MAC, when you go to make a setup for an ADDON track, look to see what default track it was made from. By "looking" I mean, check out the features of the track, look for familiar signs, then use your default set for that track, run all 3 lines, till you find the fast one, usually with addons the line is on the bottom, then when gearing, try to use between 4.60 - 475 on all tracks, if you are using auto, none of our sets will help you. Try using DB, or Bullits sets, they are usually for Auto, but you need your 2nd gear to "tweek out" if you are using auto, that way you won't lose any speed coming out of the corner, that's where we "shifters" gain our .2, you are bogging, while we can shift and stay up to speed. So try bumping Shocks 1st and 2nd gear up from exe: 80 65 460 to 85 70 460, and see if that helps. Hopefully you can start making your own sets now!
