Rear spring mount question

I'm getting ready to fab up the rear spring mounts similar to my buddy's setup, but I may go slightly different. Since I'm lowering the mounts anyway, the mounts will be lower than the frame "rails". So I got to thinking. Why not take this a step further, and actually reduce the amount of fabrication very slightly, and move the springs inboard a bit and put the mounts directly under the rails? By doing this the rear axle will have more flex (more effective up and down travel of the tires for the same movement of the spring), and also let the tires move the spring easier during flex because the tire will be further from the spring, effectively softening the spring for articulation. When not flexing, the spring rate would be the same.

The downside to this is relocation of the tailpipe, removal or modification of the trailer hitch, and more lean in turns on the street. Street manners doesn't matter to me now, and I don't mind chopping up the exhaust even further than it already is. I was thinking that I could maybe modify the hitch to do double duty as a mount for the rear bumper and rear spring shackle mounts. I'd have to move the spring pads, but thats not a problem.

What do y'all think?

Re: Rear spring mount question

Interesting idea Jim it sounds like some work to figure out,definitely would get some wheel travel I guess, are the "frame rails" parallel?? can you do the same on the front end of the springs? - I am going to cut the front and rear mounts on mine completely off eventually (if they dont rust off first) I am busy hoarding steel for the project now.....it's gonna need a bunch, damned xj is gonna weigh 3 tons when  I'm done...rofl...

Re: Rear spring mount question

You have covered everything there. Only negatives are what you already mention which is some reduction in stability.

Re: Rear spring mount question

i like it.
perhaps a little more body lean on side-hilling, too.
no biggie, tho. just makes things more interesting!
