air shocks on a fox??

[89LXCarb]

I have a turbo coupe rear end in my car which is wider than a stock rear end. When I get more than three people including me in the car the left rear tire wants to rub when I go over bumps. I know that air shocks would cure this problem, but would they hurt my traction? I have aftermarket uppers and lowers. My plan is to run undividual lines to each shock so that I can put more air in the right side than the left. I know someone who has a mach 1 that has done this, but it's not a drag car. Would running air shocks in this way be as good or better than 50/50 shocks?
