I have never owned a convertible that could go as fast as this so I don't know if this is normal or if I need some kind of adjustment. Last time I had the car out, it was too cold to have the top down. The guys I were running with were moving at a good pace (avg between 80-90) and I noticed that my windows were sort of being sucked out. I assume in a hardtop that window nestles in a sort of track that is just not available on the 'verts. Is this correct? Can I not do excessive speeds with the top up? Or should I be looking for some kind of tweak...
