This stuff happens all the time with kit cars.....from every manufacturer. The early CAVs had front hubs that were fine, but not perfect.....100% A OK for street use and most anything most owners are doing, but probably not quite up to the task of hard core track time. There were one or two failures where there was something that prompted it, such as hitting a curb. Not a big deal. Over time there was an upgrade (fab'd steel instead of cash alu) and now you can go beat the crap out of your front hubs on any track in the world. Not a big deal. Sounds like Andy is attempting to make it right with the customer, and no doubt will do so, so heck, all good. Fabricating up some new wishbones is an easy task for the skilled folks at Tornado.
I realize we're talking about suspension here, but it shouldn't be a big deal. Once, I had a wire wheel come right off the front of my brother's MGB while doing about 60mph down a back road...the wheel went into a farmer's field, rolling almost all the way across the field. I went and retrieved the wheel, found a spare spinner in the trunk with the spare tire, put the wheel back on, banged the spinner tight with a rock, and off I went.
We're not driving Toyota Camry's and Chevy trucks here, there's going to be a bit of evolution in design with these cars....
