Attached is the setup I ran from the Speedtech Grand Prix, I ran the 17.5 no timing class. I loved the car, the setup was spot on, too bad the driver isn't so hot.
Anyway, for those of you running in similar conditions maybe this will help, basically what Jilles told me to do in his thread.
I didn't have time for any practice and I crashed out of heat #1 with my battery tape getting cut. So no time to try a gear diff out back or up front, but I think I could have knocked off another 0.2 or 0.3 per lap in all honesty. I felt like my car was lacking some forward bite on corner exit. Corner entry and mid corner was an improvement over the kit setup on this track.
Take a peek, feel free to ask questions if you have any (or laugh at me too!)
Thanks,
Brett
