That thing looks cool, thanks for sharing. I dig the bumpstop up front in the original location.
I've toyed with this type setup, but I wasn't clear how the "air shocks" or "coilovers shock" would handle to the "side" forces seen by struts. Also to get an improvement in stroke, you have to get some crazy long lengths, and they start to become unpractical. I also kinda had a feeling they might not last, but never got to try it. I had one other idea, but have yet to pursue it may happen someday but really I'll probably just do double Aarm if I want this IFS still.
Looks like your pretty skilled on fab, so have you thought about this more traditional double Aarm setup? Just fab a "new" top Aarm and then use a more "regular" shock mounted to the bottom aarm(which will give you some more clearance for longer stroke). Find like a smaller donor car and you may be able to do it on a junkyard budget.
At the point you do get the travel, you may see that the CVs dont last. Are you having any problems with the front CVs now??
