By the way, you and I agreed that Diamonds Edge (T4 as you mentioned) was a very tough / sharp turn to get our car(s) pushed out of quickly (crushed our momentum)... I actually found it of immense FUN when downshifting from 4th to 2nd right before, and then managing the throttle out like crazy!
I could really feel the FR-S' tendency to oversteer there... But so much fun, and downshifting to 2nd gave me that extra push out of it, which was what I was needing... Had to be careful with managing the throttle, but it was great excitement and that turn became my favorite at Houston MSR going CW.
