I hate Interlagos............!
Up to Team: SUPEROO
Well, for me at least, I find this track to be all about rhythm...it actually helped to count out load at first. THe other thing to realize is that a lot of the corners in the twisty bits are reducing radius, which means your apex is going to be deeper into the corner than they appear at first glance. Also watch your downshifts. Downshifting too quickly can cause your car to snap-oversteer...if you're careful, you can actually use this as a trick to get yourself lined up for a strong exit from the corner, but it's a trick you really have to practice and even then it can bight you on the ass. So for me, I tend to downshift through the corner rather than all at once...and that's what I mean about rhythm...there's a rhythmto the downshifts...get the rhythmdown and your lap times will go down and your confidence will go up.
As for setups you could check the SDL section. I believe there's a setup from last season up there...not sure how well it will transfer to your car but it certainly won't break anything to try it.
Thanks AJ for the link. I think that may help a lot. Now to just find the time to really set down and try out the hints.
