Yes tire shake is a problem for sure... I put some home made slapper bars on it that helped a lot, but original springs and stock shocks and soft suspension bushings make it tough. I failed to keep an eye on my tire pressures, and when i finally checked, thay had crept up to 28 psi. Dropping them down to 25 help a lot to launch it.. Finally got under a 2.0 60ft. I do have a 9 inch 31 spine and 1350 joints in it. It was never meant to be a race car but got pressed into service because my others are not race ready. New springs shocks and bushings are on the list for winter project
