Just a couple of points, most states will not allow lifts over 2" to be engineered on IFS vehicles. That is one of the reasons why we have stopped designing bigger lift kits.
Long travel kits are good but mainly designed for desert racing and jumping. A lot of the kits in the states are well designed but illegal in Australia. A common reason is because they extend the wheel track beyond 50mm which in most cases, can not be engineered.
The track width limit varies between states? 50mm is the maximum allowed from "factory". That doesn't mean a wider track cannot be approved by an accredited engineer. Most US long travel kits are not legal here because they use spherical bearings and heim joints predominantly, which are a no-no here for road use. I'm looking at using polyurethane or delrin bushings and factory balljoints/steering joints, etc. IF I feel it's worth my while, and my engineer gives it his stamp of approval, I'll market them IF I can get product liability insurance. The CAD, Solidworks and FEA can be done at work (we have the software for this) and we have a great laser cutting place close by with folding and bending done in-house. All I have to find is a good FG place to make the guard extentions and bedside pieces to cover the track increase.
