I was always planning on stretching the rear, but now i have changed my mind for good.
I have never had a problem with the departure angle at all, or the approach for that matter. The gas tank is right behind the rear axle, and would require me to move it into the bed, which is already tight on space as is. The compcut on samurais is a pain in the ass with alot of body work, i would cut the entire rear, link it, tube it with airshocks and fuel cell before i tried stretching the rear with springs.
The front, all i have to do is move the steering box, 3 holes, and extend the steering shaft. I am going to weld shackle hangers off the front of the frame, and drill holes forward and up, (as close to the frame as possible) in the spring hangers to get about 3 more inches than i have now out of the front. I have wanted to build a tube front clip anyways, and this will make me have to do it so the tire doesnt stuff into the front of the fender.
Stretching the front will also give me a better weight balance with the engine more in the center of the vehicle.
After doing all this i will have a flat belly and the spring mounts will be up and out of the way. I will then lower the entire truck about 2 inches like i said to make it even less tipsy.
If i come across some bigger tires than i will run those until the axles break, then i have my yotas that will bolt up directly with some driveshaft adapters and hy steer arms. The truth is though, i like being low to the ground. I have my 1/4inch angle sliders, and a 3/16inch skidplate, and it slides over all the rocks. I really should shave my diffs to get rid of the drain plug since its probably rubbed down to a nub already.
