I tried looking on the forums for an inquiry about this subject and found none, So I decided to go ahead with this question. What would be a good Brand of adjustable Rear Shocks for my 81' Malibu? Given that I have got bigger tires on the rear wheels and Exhaust line that sticks down a bit, I need something adjustable but at the same time stiffer for pot holes and such. Its a subject I am not entirely knowledgeable about or calculated but suggestions will be appreciated.
