Ok, new question, I was checking how much steer my boys cars from last year had. the one that had all the good stuff was set where is mover over 1 inch after traveling forward 15 inches. The car ran well and on a dirty track it ran a best of 3.1578. I kwon that is nowhere near what cars are the NPWDRL run but is had 92X axles and BASX wheels and was a wafer thin car. My other sons car ran slower but not by much, his car had steer where it moved over 3.5 inches after moving forward 15 inches. It use all out of the box parts but I did use DD4H polishing stuff ont he wheels and axles, the car was not the best on COM and aero but it is what he wanted. I need to understand if I need to add more steer on the fast car or leave it alone. We are building new cars this weekend and I want to know what direction i need to go as far as changes.
