I'm not a licensed racer nor an expert here, but I've put in a few track days at Sonoma and High Plains Raceway.
My best lap time in my unprepared AT supra w/SC2 200TW tires was 2:10:22. I could lose another 2 seconds with more track time but that is fairly consistent with other drivers who...
AT Supra owner for three years. Looked at the G8X and decided to pass. I started looking at Porsche this week and did a lot of research as well. Porsche started putting the larger GTS turbos in their lower-end S and T 992 models. With a simple $2,500 tune, you are pushing close to 500 working...

Sounds like road noise and the duration of the hum changed as you slowed. Are you on concrete roads or asphalt. And I suspect new tires are not going to help much and may make it worse if you go 200TW or lower.
It's been said already but 90% of the wrecked Supras are front end -- get it together kids -- meaning you can get a used hatch w/glass for cheep cheep cheep. There are probably 10 to choose from at any given time. I looked into this option for my RB A91 so I would not need to repaint but only...
Absolutely - And you can point people to it when they ask questions so everyone can get the same info. Good luck with the next adventure and keep doing what your doing in the unlock space.
