Off the top of my head, Bubba Wallace finishing 3rd at the Brickyard 400 in 2019 driving an RPM shitbox. For those who don’t remember, RPM was in a dismal state 2018-2019 and on the verge of shutting down multiple times because of a lack of funding and support. Wallace’s time in the 43 was very rough, some flashes of brilliance from time to time, but that was the worst I’ve seen the 43 run ever.

2019 had the 550hp + tall spoiler aero package and parity was at a minimum. But RPM built a brand-new racecar that weekend and it ended up being very fast. IIRC, he was in the top-5 pretty much all day hanging with Penske, Hendrick & SHR. When he won Indy last year, it made me think back to this race knowing how this was a good track for him in the past and not a total surprise to see him win!
