for track, i ran a 22, 25 mm F to R setup. pretty neutral. if you are going to run on a dirt track, you will want to run about an 18 front 21 rear. you want your car to have a bit more sway so you have more bite on the outside tires
rockin 70+ hours a week at work and still trying to have a social life!!!
