Tom,

We only reinforce the inner end, mostly to take the load off the joint where we shorten the tube. Our control arms are a couple of inches shorter than the 3.8S or 420 - they actually duplicate Series I XKE dimensions. That way we can use standard ('60s vintage) offset wheels to get the correct track.

We typically use a short "tie-bar" between the rear shock mounting pin and the outside wishbone, but its primary purpose is for tying the car down on the trailer. It doesn't do much for strength.

At 3000 lbs, and using very stiff springs for racing, it couldn't hurt to reinforce the outside ends of the wishbone. If you could run a channel from the inside wishbone to the outside, and tie-in the shock mounting pin, that would be ideal.
