I was on their site and it mentions they now have a universal engine mounted tubular K-member. has anyone have any experience with one of these? Durability? reputation of AJE?, etc... Does it change the track width and/or wheelbase with using stock fox control arms? I would like to buy it, but am wanting to get all the info I can first, thanks. Oh, and eventually I'll get coil-overs, but not yet.
