Dunno if its just my stilo that does this but when driving on bumpy roads(typical english roads=not off road) it some times grounds and it isnt lowered either. i've had it in the garage as its only 9 month old and they say its in and every thing is the way it should be. so becaus o this i don wanna start with lowering and puttside skirts on t because just get messed up. any avice would be appriciated.
