we have a DRC with the factory sway bar deal on it. we had trouble with the car pushing but it turned out it was another problem besides the sway bar. however, the last weekend of this past season (funfest at lawrenceburg), we put Dickies Gaines in the car. the first thing he asked that we do, was remove the sway bar. he feels it "just binds the car up". without hotlaps he went out and came from 9th starting position to win the race in 15 laps. the car ran great all weekend w/o the sway bar. we're definitely going to start the season w/o it. if i were you, i would buy a car with a factory sway bar set up on it but, that doesn't mean you have to use it. it's just another option you have at the track. some guys love 'em
