It was still drivable in grip, and shows the full potential and power of Assoluto Racing's physics engine. Toyota Supra Mk4 at Waldorf. 276hp and stock weight.

Yes. Still testing. Testing cars for an hour a day 30~40+ laps at Tsukuba is less demanding to my neck than editing a video lmao🤪

Anyway. If you guys are interested in JDM, there's a good chance you have seen Ayrton Senna driving NSX around Suzuka Circuit. One is him driving a prototype test mule on full circuit, and the other is him in NSX-R, on Suzuka short circuit(one with the Spoon and 130R). For the NSX-R, there are side by side footage of Nakajima Satoru and Kurosawa Motoharu driving the same NSX.

What you will find upon closer inspection is: that the speeds at which the cars take the corners are not billion mph, despite them being Formula 1 caliber drivers. It's usually 100kph~140kph, and 60kph~80kph on slower ones. I saw 180 in 140kph out on 130R. So slow by Assoluto Racing or any game's standards, but if you think about it, they are terrifyingly quick. And they still need plenty of countersteering and throttle work to keep the car smooth, and on the road.

Currently Alpha Tauri released a video of Pierre Gasly driving an early version of NSX on COTA, and it was the same story, or... worse. Gasly oversteered on almost all the tighter corners he braked into. We don't have the bigger picture of course: the car might have had cold tires or the track condition wasn't ideal. But what is certain is that these 80s~early 90s cars does not like trailbraking that much compared to modern cars, and they will bite you with oversteer if the conditions are slightly not up to their standards.

Back to this Supra video of mine, I like Waldorf Reverse because the first corner after the chicane is literally Suzuka's First double apex right hander, but mirrored. You can approach it at full speed by cutting the chicane, or slow down by using the chicane. It would be really dangerous to take that corner at full speeds after that long straight on any normal cars(in real life of course), so that is some attention to detail on the dev's part.

Anyway, Waldorf is a good test venue for reference. On the map, it looks like it has lots of tight turns but they are pretty fast turns. A lot of them are swooping corners, similar in terms of speed to the Tsukuba's last big corner. Even slower hairpins are slightly quicker than Tsukuba's, considering there are no camber on Waldorf's.

There are tons of full onboard videos of Supra and NSX taking on Tsukuba Circuit, Senna and others driving various versions of NSX on Suzuka, and the information regarding the speeds at which they took the corners on those circuits. This Supra of mine was a bit more oversteery than I would've liked, but I think I am really close. And it can be fixed.

Things I looked for: lift-off oversteer on fast turns, oversteer upon hard trailbraking into corners, rotation on slow hairpins, cars stabilising on acceleration, car de-stabilising on twisty bits(directional transition rolling-fishtailing), understeer when braking hard into a corner on excessive steering lock, understeering on fast turns while accelerating.

Only thing that lacks is understeering upon acceleration, which cannot be solved using the setups cos the AR physics engine is programmed to make the cars understeery, so any attempts to solve that understeer would result in oversteer. I could observe other elements as expected.
