hello guys im going to get a honda city 2010-2011, my dad owned one before and my brother told me that it's not stable on high speeds somewhere around @140 kmh,and I also heard that if a heavier car passes by your side the car shakes because of the other car's air drag. Now if this is true what would people recommend for stability, better rubber,lowering the car, maybe a strut bar? I really need the help I can get for the stability and safety,for me an other fellow drivers on the road.
