ok i've never really played with stoppies much till lately.... like the FIRST time i role one instead of just doing the gay *** donkey kick stoppies was like a month ago... anyway i've gotten wo where i can pull em up from 30-40 mph but i'm only rolling em 50-60ft i know i COULD roll em farther and i know where stoppie bp is but every time i get cose to it i get bad tank slappers and damn near lose it. i have a 954 front end on my f4i and i feel like it shouldnt get wobbles this bad and that easy but it happens about 90% of the time that i yank it strait up close to bp above 25 or so... below that im fine.... on and the tire is in great shape running about 27-28 psi. is there something i'm doing wrong or something i need to check on my setup or what
