I just received mine today and it wont go in bj4 properly!!
i can get them in the car using longer screws through the straps, but the joining lead prevents the shell from going on, the balancing port is to high on the plug!!
Gotta say i'm unimpressed considering how long its taken to come to market! That it wont fit in cars it was supposedly designed to fit in. Had such high hopes after my great year with the 4900 stick i have.
