Spec Neon definitely lives on at Waterford Hills. We started the class there and intend to continue it as long as people are racing.
As far as the Shadow front knuckles - don't bother. That setup will not allow for any camber adjustment, unless you have camber plates. Camber plates are not legal in Spec Neon and the shadow knuckle assemblies are not legal in ITA.
Just use the ACR hubs and check your bearings regularly and replace as nec.
