I will be swapping the wagon's rear axle for the 3.73 / Auburn / LS1 Frankenaxle I've been working on forever. I pressed new poly bushings into the stock upper and lower control arms, but I am debating dropping some coin on some aftermarket solutions. UMI seems to be well-engaged with the G-Body Forum. They have literally 12 combinations of rear control arms. This car will not see the track much, but I might autocross it. I have read that urethane bushings cause the suspension to bind through the range of motion when pushed. I like their Roto-joint solution, but wonder whether having them only at one end of each arm (upper and lower) is adequate. What about the solid upper control arms with the urethane bushing, then pressing in loose Roto-joints into the axle's upper mount rings?
