I have a rediculous rattle coming from my trunk, it has been there since I bought it I have a oem spoiler on the car I think it may be the trunk or the trunk latch, What do you guys reccomend this is so ******* annoying

 

When the trunk is close, can you move it up/down? If so, adjust the latch on the back of the trunk cavity so it'll close tighter. Not too tight or you'll have a hard timing getting the trunk to latch when you close it... you'll have to slam it really hard.

 

I **** you not, check your jack. Either that, or like the other guy said, adjust your latch. 2 10mm bolts is all you have to loosen and you can slide the whole thing up and down. No more rattle.
