Saturday night report.
Conclusion......I don't think I can build a reliable diff!!! ARGH!
Qualified 2nd in 19t. There was definitely more in the car, but did not find the setup/tire combo. The track is usually sprayed, but rain washed away most of that Thursday/Friday.
The Demon is a VERY stable platform. NO torque steer. No twitchy...as in normal TC3 fashion. Started with a very basic - middle of the road setup......the car would react to high speed chicane (as in full throttle....right.....left.....then 90 degree onto the straight.......VERY fast).
