Hey thats great! Thanks for posting. Why did the T400 and T430 not enjoy the same popularity among teams as the T330/T332?

I could be wrong and should be corrected I heard that the T400's rising rate suspension was extremely difficult to dial in (pitch sensitive?). There were stories of T332 suspension being adapted/grafted to the T400. In Europe the T400's did ok. In the US the top teams reverted to the 332's and so (I suspect) development on the T400's suffered.

Thanks. Yes that was my understanding too. It seemed that the T400s were potentially faster, but that there was a much smaller window to get the set-up right with them. At least thats always been my limited understanding of them. Kevin Bartlett joined this forum recently. I was hoping he might jump in here and give us some first hand insight into the differences, as he raced both at the highest level during the '70s.
