I have the AEM FWD setup too, and it was actually installed at AEM (since they were developing the v2 CAI on my car at the time).

Anyway, I haven't had any problems with it. They did have to do some grinding (on the hub I guess, I didn't see it). Maybe this is an issue for the AWD setup though - I don't know.

While I have not used this setup on the track, for street driving it was definitely an improvement. Modulation control is increased, allowing one to achieve theshhold braking easier. Unless you do track driving or extreme canyon runs, IMO it is a good solution.

And they look mad kool, yo! ;)
