K&K autocross insurance specifies a max speed of 70 mph, if memory serves. Otherwise you have to insure it as a high speed event.
That's not actually true. Partially, and easy to interpret the situation that way, but for sure K&K isn't specifying a top speed.
Having gone through the whole insurance thing with my club on a national level, you quickly find out that the insurance companies are actually fairly open in their coverage. The #1 item is that you follow your own rules.
And that's where the idea that the insurance is forcing rule X.
The reality is that sanctioning body Y says that rule X is required. And since rule X has to do with safety, it's now required by insurance.
If you want to see this in action, all you need to do is visit multuple club events- and know that there are only 2 companies in the US that provide motorsports insurance. And both of them use the same underwriting group... So for all of the clubs who have slighly different safety rules, they somehow all have the same insurance.
Our club allows minors with a license to compete as long as they have a waiver signed by their parents/guardian. Another local club has no restrictions on what helmet is legal for autocross. IIRC, SCCA's own open track rules allow open cars w/o roll bars. AROC does not. Etc etc etc.
It's all about your own club's rules. Which is why I was a major PITA when it came to making up new safety rules for the club. Good idea in principle, but what does it really mean for the club?
Sorry for the digression.
Like Adrian- I did an SCCA event at Flat Rock. It was interesting. I also did the GRM Challenge in 2000-'02. That was a very fast autocross on the Gainseville track in the back 40. I think I calculated me doing 70mph on the sweeper (8000rpm, 2nd gear, with all the numbers crunched- and I'm sure of the 8000rpm, since it was the hard rev limit, and I hit it).
Even having done a lot of track days, I'm not a big fan of super fast autocrosses.
