Its still a Vette system (or pretends to be), one of 3 or 4 different versions, none of which impress me enough to install under a different vehicle. I would probably be way less impressed with a system that has been narrowed to "fit" more vehicles .I've seen enough poorly designed "kits" to not have a desire to look at another one, let alone do the work required to make most of these "kits" function.

I've modified frames and bolted the old Mopar cross torsion bar cradle onto different vehicles back when that was the thing to do, as well as more then a few other specially built cradles that were suppose to bolt onto your existing frame. In most cases, you cut off the existing front (or rear) frame, and build something to hold the cradle.

The OP asked what we knew. I've responded. I've actually done this stuff with vehicles that have actually been driven, and have been called in to help several get a "kit" to go down the road safely.

Its a lot of work for the small amount of improvement you probably wouldn't notice, unless your taking up road racing or parking lot timed events. For something street driven, those fancy sub frames only add to the cost for very little (if any) noticeable improvement.
