ive used the $30 fixed length arms on a couple of street/autocross GM cars before, and they held up well. fixed length would require some headscratching for me. currently have 15k HARD miles on a set of UB machine arms in my el camino.

thanks for the headsup on the oncompatible angle. I figured there was something I was missing just looking at the picture.

anyone ever tried using the fixed arm version, and if so, how did you do the mounting?
