Speaking of lifting the front wheel...

My. Trying to figure out if the bounce was shock related or came from lifting the wheel. Interestingly, Pete at TC Kline thinks I should disconnect my rear sway bar.

I'm pretty sure coilovers and camber plates take me out of AS.

I didn't notice at the event but I think after watching the vid that some of the bounce is due to the wheel lift. But if you watch the uphill part on the last run in particular it looks like there is an extra bounce in the suspension before it settles after putting the tire down. So to answer your question, I think the bounce is related to both the tire lifting and the shock settings.

My best was a 56.5. Not where I needed to be, although I slowed down a lot on my last run with Josh as a passenger. The car drove pretty poorly with the ballast.
I'd say I left 3-4 seconds out there that _I_ can recover. And that's with a suspension that isn't set up, aligned, or anything. All in all, I'm pretty happy.

Given that I never really walked it, got lost on my first run, and never got anywhere near aggressive enough...

Actually, it really is a significant difference, Josh.

still, great data. the upshot was that I was able to run. if not for that, i'd have had to skip altogether. threw the rear sway on the car tonight. seems nice. unfortunately, I dropped the rear about 3/4" too low. this kind of puzzles me as I lowered the rear 1/2", and it was over half an inch too high. oh well. i'll have to fix that tomorrow. |

The fast S2000 was in the 54's on that course.
I was in the mid 55's and I suspect if I could have put everything together I could have been in the high 54's. Pure speculation, though. John |
