just got my wing installed a couple weeks ago, but i only have 2 bolts holding it down (one on each side). it's not until last week i got the other 2 bolts for the center. is it still necessary to put on the center ones? and also, it's not sealed like how you can get it stock from the dealer, so there's a visible space between the wing and the trunk if you look close enough. would it be bad if it rains or if i wash my car? or would the two center bolts take care of that? ...or should i just get it sealed??

 

I have the same wing and it wont seal with the four bolts but I dont know if you can just buy the seal (if you dont have it). Hope this helps...

 

Just make sure that when you have the new bolts put on, have the sealant chalked around the opening to prevent any leakage. Also, have the shop put the sealant around the edge of the spoiler to completely seal the spoiler from any moisture getting inside the spoiler. PM me if you have any other questions.
