163.1mph at Daytona in a stock horsepower SS 1LE with a tailwind and a draft!

My top speed was typically 161-162mph without a draft or a few mph lower the next day with a headwind and no car ahead for drafting.
I could've gone a little faster by braking about 1.5 seconds later like on this lap (where I still braked a bit too soon) but that would've been risky since the cars not too far ahead of me didn't brake that late.
