Ran a 1:27.9 with my 2021 Miata RF at TMP. This was with Kodawari & Morning Meets for their 2nd track day of the season. 

Wider tires and some coilovers would make a huge difference. The suspension was struggling and I went through the stock brake pads in 4 sessions. Not bad in stock form but suspension & brakes are next on my list.
