Lots of good info here. Your 1.14 should not produce poor ride, especially with a decent shock. The fox shocks that hotchkiss sells are rebound only adjustable. Their is always limited information around what spring rate the shocks are designed for. This relationship is critical and usually mismatched to some degree.
The bumpstop issue is easy enough to check at ride height. I run thr 11/16 without issues or poor ride quality.
I was never a fan of the qa1 lower arm. The cantilevered attachments can't be as stiff as the originals. Besides, the inboard only sway bar mounts and rubber bushings don't make any sense to me. An oe arm, my delrins and box plates, your in business. Add a hotchkiss sway bar with the beefed up oe style weld on brackets and all fits perfectly.
Chassis stiffness is also a great point. However, most make the mistake thinking the frame connectors are most important. The twist comes from the motor compartment, where reinforcements are the most critical. We developed the rad supports and inner fender bracing at XV. USCT has adopted those designs today.
