I ran my new car for the first time this weekend. It Is a back halved 69 Dart with ladder bars an single adjustable coil over shocks. It went 1.42 @ 60' 10.07 @ 1/4 mi. The car instantly goes to the right and then straight after I correct. It only picks the front tires for a very short time. Should I just add some preload to the right hand bar, or make some other adjustment. unfortunately I do not have access to a scale.
