Mark Payne - I missed the part about the springs being off the chassis. However it makes sense since the Corally car prior to the 12M did not have tweek screws in it. If the tires were true, and the front chassis height correct, it tracked very easy and straight. I'll have to try that on the T-Fource and maybe the Gen-X
I do have another question for you as to the affect that track width has on the car. If the rear is at max width, a narrow front will make the car do what? If equal front and rear, then what??
Thanks
