I can't see the pic due to work popup blockers Tony but are you sure you have the right cold/hot tyre pressures sorted before and between runs. If you are out by a couple of psi it could make the difference when you are getting back on the power. Did you speak to John about those R888's and how to run them.

Also if you are getting on the power and your front wheels are still turned it will understeer dude it is very hard to avoid. My betty is notorious for it, no matter what tweaks I have made the understeer is still there if you get on the gas too soon and the car is not completely pointed at the corner exit.

I have a 22mm whiteline sway bar at the rear on stiffest setting and the car is not tail happy at all...

Edit - what Burke said. I need to do the same to learn more and progress from where I am.
