I haven't noticed any building up of *** either. I'm just talking
about the groove that is already laid down. For instance, at Mills GP,
the right hander just after the chicane. The car often will hop going
into that corner. It's also noticeable on the short Birmingham course
on I think it would be turn 4. It's the left at the end of the first
long straight. The track is really black there. If you drive in real
hard an place the right side tires in the groove, the car will start
hopping. It happens occasionally in other turn. I think it's the same
thing as what you are feeling while braking, but the car seems to do it
under more lateral acceleration as well. Looks like the racing school
lessons paid off for the ISI team - and for us!
Then again, maybe I'm just imagining it. :)
