just purchased this beat up 2015 FRS (BRZ, 86, whatever) with 75k miles. First track outing with the car, as you can see, UNDERSTEER !!!! Due to a no-name front sway bar, and not enough camber. Weather was decent (IAT number is wrong) at ~75F. Oil temp was ~265F (shot up to 277F later during 88F weather). This was the first-ever track session with the car. This session was also the first session of the day, so the track is a bit dusty. Could have easily gone flat through T1/T2 (did so later in the day), but didn't in this video session. Probably a high 2:-01s in it as it sits.
Track: Autoclub Speedway Roval
Tires: GT Radial SX2 215 45 17 on 17x8 6UL. Tires are on its 4th track days, but it didn't lose much grip since new.
Mods: front 20mm sway bar, not sure of the brand (no info on the bar).
