Ran the car last...Nothing but 13.0s all night. Rims werent balanced and was shaking really hard going down the track. Adjusted right height to fit the new tires and it felt like the alignment was off (car was pulling to the right). All in all I was still pleased. Will get the rims and slicks balanced and the car aligned. I haven't put on the Xcessive manifold (N1 runners ported) and N1 pistons. Just want to get the car back into the 12.9 or 12.8 area
