DOH! cant treat the G80 rear end that way! its kinda touchy(aka pos)...mine did that a few times but it never took that long to unlock. the things that i found to work was to take a sharp slow right turn. if that dosent work try stopping on a long straight road and stomping it from 0 to about 80 (treat it like a 1/4 pass). that worked once too. if that dosent work i dont know what to tell ya besides find a good shop and dont put another g80 in. good luck
