There are a few differences between my design and Quadvan's.
-I've pushed the axle forward 1.25". There's now a big difference in clearance between the tire and the lower rear of the fender. My tires used to lock up because they'd get stuffed into the fender around certain corners. I hated that about Quadvan's set up. I shouldn't have to cut my fender or trim the body to fit a tire on the van especially since my old tires were tiny.
As an added bonus, because of where the axle is now, I can get about .75" more bump travel than the Quadvan set up.
-The rear radius arm mount is lower, making the arm more horizontal, which in turn increases the caster (steering axis inclination). My van had 1.5 deg of caster before I started this. It wandered in the lane, return to center was sluggish and the steering felt...blah... My intent with this design is to increase caster to ~5 deg.
-The radius arm is also modified to get even more caster than is available with stock arms.
-I'm using an off-the-shelf Fox shock and Moog progressive springs. Right away I could tell a huge difference in ride quality. All of the little jarring pot holes on my street are now smooth little bumps.
-It's also obviously lifted more now too. I'm up 3"+ from where I used to be, including the change in tire diameter.
