If ya know your tire rollout you can use gear selector in the tool box. Click on the menu icon on the upper left of the screen and search in there. Anyway, anywhere from 5.83 gear to 6.50 gear. Just depends on how hard ya want to twist it. Good lick, Race

I think you are going to wind up closer to a 7.00 gear. I would recommend talking to some of the drivers that run at the track you're setting up for and find out what they are running. There are a lot of things that have to be factored in if you are going from scratch: tire size, track size, banking, turns (sweeping or hairpin), engine displacement, and some other things. I think you get the point. Talk to several different drivers and get a range of gear ratios - ie. 6.50 to 7.00. I race on a 3/8 mile and have seen every thing from a 5.83 to a 7.00 in street stock.
