I know convertibles aren't as sturdy as regular body styled cars hence leading to some twist and flexing but just how much should I feel? My 91 325iC has brand new shocks, struts, control arms/bushings and tires but it can be a pretty bumpy and unpleasant ride. I know it was never wrecked and all of the new parts are stock OEM. It seems to be worse with the top up. I'm sure that the wind hitting the top adds to this some but it is really bad. Feels like a Jeep Wranger. I am going to have the wheels rebalanced Tuesday and see if that helps. Maybe they forgot to balance all four tires when I had them put on. Please advise. Thanks
