Unable to rerun my car before the race Saturday and stressed to the max about my car being stable...running on an aluminum track, rail riding on 3 wheels rear wheels flat....COG .73 just added a 1.8oz sweet spot 2 to the rear so.......any wisdom to ease my mind? Should I even be concerned with it being unstable? I have 23g on the front axles. ...BSA 2.4G wheels and DD4H gee fenders. My OCD is on overload!
