Bimmerman_87, I have an '08 e90 335xi.
I ended up going with a set of KW V1's from Turner. Think it was $1485 shipped and just over $300 installed w/ alignment.
You might be able to find them for cheaper, but they were pretty evenly priced every where I remember looking. Keep an eye out this weekend though, might find some Labor Day sales.
