I plan to make new mounts, with a goal of dropping 5 pounds off the front axle. Basically exactly what we built for my buddies FProd car.
Once that and other projects are taken care of, I like the idea of using the stay rod allowance to stiffen the K-frame.
I still don't get the rule, and I lobbied against it because it does not solve any issue that was not already correctable before. However, if the allowance is there to drop front axle weight and stiffen the chassis, I'll try to take advantage of it.
