I would love to see X-Rays of those welds. After seeing the failure on the non-road race version on TGO (yea, I know, he didnt take heed to the warning on their website) I have suspicions. I feel like a fabricated spindle like that should be welded to the same strict standards that are used for AWS D1.1 3G and 4G tests or something similar to it.

I've had both the drag and roadrace versions in-hand. I'm confident with the beefier roadrace version! Yeah, the other guy road raced the drag version, and refused the upgrade when it was offered to him (post failure). I keep it bare to make it easier to inspect. RaceCraft put their best guy on these. I feel fortunate to have them.
I do wonder about aftermarket tie rod ends that might allow me to fit them inside an 18" barrel...hmmm....But
I do prefer 17's and some
sidewall at Road America. Technology improves and offers alternatives.
By altering the steering arm, you mess with the angle of the tie rods. Then you could alter the drag link to compensate, but.....then I'd get lost and over my head. Here is a crude drawing of the front steer.
This proposed set-up is a clean sheet design and looks promising! I'll look-on with envy, but it's beyond my finances.
I do tour with my car - want to drive it in all the lower 48 states. I have MS & LA (Nawlins trip), and a New England trip (everything North of Yankee stadium) left. Delaware was difficult to incorporate, but I did it. I don't think 315's will be practical for touring. Though this design will keep them flat.
For now, I try to keep scrub close to zero by 8" wheels, SAI mods, and use moderate camber. The drop spindles and lower PHB help the roll axis inclination, also. And, I continually look for ways to be able to go wider, but I drive my car alot - 240k and counting (all mine, original owner). I'm lucky to see one HPDE a year. These cars are fun to drive, and with low unsprung weight and an LS2, it has exceeded my expectations.
