That last turn is going to be the bane of me for this challenge - I still haven't found the perfect line/speed combo yet. I do it differently each and every time. I'm fine with all the previous turns, but that last one is a mystery to me! I'm sure that I've come close to nailing it, unbeknownst me to me of course. Oh well, I've got a pretty decent time going right now and, even if I could or couldn't shave off a few tenths with a dialed-in last turn, I'd be fairly happy about my time for this challenge.
On a related note, I've enjoyed the lack of spin-outs with this car (especially compared to the last challenge)! I mean, I've still spun out if my rear tire went off course - especially on the last turn - but that's somewhat uncommon.
