depending on who you buy the GT4 lip from, you might need to trim your ducts as it might be too long, you'll need to cut your undertray felt if you still have those... Pinnacle motorsports makes a good one that works with the GT4 lip also.
If your strictly tracking run the ducts, but i don't think it's required...if you have the option...as this one is a bit expensive id get the ductless Bimmerworld one.
Personally, I think the GT4 V2 doesn't do anything since they cut it shorter, but hey, at least it's street car friendly. I like the much longer GT4 V1 as it will act more like a splitter. Those extra 2 inches, I think, do wonders. (that's what she said)
If you are going to pair it, then the much wider and larger GT4 V2 wing would be ideal for "street/track", or the M235/240IR wing.
For something more track-oriented, the APR GT250, or ideally the Bimmerworld LW rear wing.
the wider GT4 V2 wing.

Now I'm curious about the GTS vs various GT4 variations of aero kit. I know the ran the first ones with no areo, but I don't know much about the evo updates. If that's even what they were called.
