Face first into a wall you say? Hmmm....I've seen video of runs at Waterford, and think I know the wall you're talking about. That's the thing that keeps me wondering if I should try ANY track. I couldn't afford the time or money to fix the damage, should there be any. I suppose you'd have to budget for it and/or get "track insurance" which I would need to research and see what, if any, is available. I hesitate to call my agent. They might just raise my rates at the mention of the word "Track"
More research to be done for sure and I think that joining the local BMWCCA might be a good place to start.
