I would be buying the PA mildsteel (DD car is mildsteel is my best bet).
The K member and motor mounts and spring perches with shipped come to 360ish. Like I said I will be running stock springs and a arms. I would be buying from Matt Hill Motorsports. Matt is the man, he is the one who tunes my car. A very good stand up guy.
I would love Dan to chime in and give me his thoughts I PMd him earlier. I don't know if the unit he sells works with stock a arms. I also wondered if he sells any brands. I doubt since they make there own.
