Have a look at this video we did of chassis chatter. Couldn't post a video up here so have put a link to our FB homepage instead.

Interesting. :)
 
Have you videoed the same car with the chatter removed?

Drove slower, as I said in the text we were inducing the chatter by overdriving it but it was/is still symptomatic of that chassis and when really well tuned doesn't really do it. I think too much grip is the typical culprit.

We had that problem with the International 32 chassis year ago. It ended up that we were running the front end to low. The inside rear wheel lifted causing the inside braid to lose contact. A few thousands worth of additional spacers on the guide flag solved the problem. The International 32 is only 2½ inches wide making it more susceptible to chatter.
