I'll check my settings on Evora when I get back to my PS3, but I did the 90 lap Laguna Seca endurance event and it handled great and finished far ahead of the pack. Good little car with a few tweaks much like it's sibling, Elise.
Update:
Here's my tune, looking at it now I think it can still be better. Haven't touched the car the in a few weeks and I've adapted to the tuning guides much since then, but here's what I used at Laguna Seca endurance. Note, I was trying to keep the power under 300hp with a new engine in configuration for self limitation, but broken in it's 320hp and this car goes much higher I know.
