Let me not be misunderstood. I'm not concerned with axle tramp (I mentioned I'd seen an interesting setup on Wally Swift's Alpine which involves use of horizontally mounted shocks subframe to axle - not sure what it does, but if you've seen Wally at an auto-x.....). My concern is with rear spring squirm. Although running Tiger leafs (stiffer), I'm looking for an elegant and simple method to prevent lateral movement of the rear wheels in turns (as in road race application). Panhard rod is a compromise because it allows the rear wheels to move in an arc with up and down movement of the body and a Watts linkage appears to allow no wheel arcing, but looks heavy, complicated and expensive. The A-arm (v-shaped assy mounted by brackets on the subframe to a single bracket on the differential housing) looks intriguing because it appears to arrest side-to-side axle movement, allow the wheels to move up and down only and, as a side benefit, resist tramp. Thoughts, analysis.....?
