So if i got a new alignment with my stock enkie's about 3 months ago and now im going to be putting on some 18's, would i need to do another alignment with the 18's on?

Thanks.

If the wheels are the same overall diameter it shouldn't really matter, however alignments can fall out of spec relatively quickly. Your alignment will also change in winter and summer as your suspension components expand and contract. BMW reccomends two alignments a year because of this. Thinking about it logically an alignment is about the cost of one 18" tire so your better off getting an alignment than eating a set of 18" rubber in 2k miles.
