Step 2: Replaced front wheel bearings. I've only driven on the street but so far I haven't been able to get any type of knockback even in high speed abandoned parking lot manuvers.
So the moral of the story is that wheel bearings are now part of my annual track maintenance plan.
Keep us posted after you try it on the race track
