I have found that if you wreck in the megane cars the damaged items will not re span on the cars. The car feels like its fixed but it dosent show on the car after it falls off.
Yes, I've had this on the 3.5 mostly.. Wing's wont be replaced after pitting for damage, or escaping for a new car.. or at the start of a new race! The damage indicator seems to suggest there's no damage, and there's no lost downforce, so perhaps in some cases its just graphical. A little off-putting never the less.
