[Jack Smith]

Thanks for your time and effort. Really nice on your behalf. Although I did not retain it all, I can now at least go back to the skid pad and redo things over and over until I see all the relationships involved.... at my own speed.

A vary unique event and certainly adds to the special atmosphere found here at GTL.

I don't have any apples but I could offer my sister... she's a real beaut when she has her lower teeth in. We hope to get the uppers for christmas

Here's a real-life scenario which shows some of the things we discussed (look under Suspension section):
http://en.wikipedia.org/wiki/Renault_Dauphine

The car was designed with double-wishbone suspension at the front (decent camber-recovery) and a swing axle at the rear (large camber variation).

When the car brakes or when you lift of the throttle, the car pitches so that the front dives and the rear squats. Because of the suspension design, you get more negative camber at the front (more front grip) and more positive camber at the rear (less rear grip) and the result is oversteer as we looked at. Overall it gives a very unstable handling with a lot of lift-off oversteer. The problem was solved with:

• a front anti-roll bar (more weight transfer at the front axle-> less front grip)
• decreasing front tyre pressure (less front grip and a more "flimsy" tyre structure).
• increasing rear tyre pressure (slighty more grip and "stiffer" tyre structure)

The result is neutral/understeer on turn-in and good amount of understeer on exit. So it is quite compromised by the suspension design. But it demonstrates how you can use anti-roll bar and tyre pressure to move the handling balance towards stability and understeer

Actually i just remembered my dad told me one of his mates had a Dauphine when they were young and it went by the name Død-å-pine which translates to Death-and-pain
