TL;DR : The problem with rear tires loss of grip needs extensive testing. Many people complaining can't be for the sake of it, some come from other sims and have actual real life track experience. Does FWD cars improvement have something to do with this?
What would be the equivalent GT7 tires Randy Pobst was using in that C7 Corvette video? Was it stock? Was TC ON or OFF?
Btw Scaff's IB-1 video seems like he had TC ON, I think it would have been better with it being OFF so there's no direct or indirect thing interfering between the actual driving and tire behavior, since it's what people are reproaching.
(I have very limited knowledge about this, please try to understand before mis-interpreting anything, these are just my two cents about the matter.)
So, without going far in physics or GT's tires model and its many cons, we would have to actually understand why the rear tires are breaking traction like that
Longitudinal grip VS lateral grip right?
Did anyone test a certain tire's grip in a straight line standing start & and low speed rolling start? And try going into a corner while coasting? Also same car/corner/tires/conditions but applying different amounts of throttle input? (in low/medium/high speed corners, and both at higher & lower gears). What are the grip levels? Speed carried?
Did anyone try that C7 Corvette with the exact same conditions just putting Sport Medium or Sport Soft instead? How does it compare? (Same tests as above). Does it now have a bit too much longitudinal grip or lateral grip?
Again, same thing with some other road cars, stick to one drivetrain first. for example FR : trying old cars, modern cars, low HP, high HP... Then again with other drivetrains : MR, RR, 4WD, FF
I think these basic tests, which are very time consuming unfortunately, would be cool to help us understand what's the main problem so we can correctly address it to PD. If there are many people complaining about grip levels, especially rear ones, it can't be all driver related. Some of them have at least played AC with street tires (which isn't perfect by any means but still decent) and have experience on tracks irl so they have a clue about what they say so we should take everything into consideration if we want GT to improve
All I hope is, if PD corrects this issue, it won't affect the FWD cars negatively and take a step back to where they were. It's the first time there is a great improvement about FF cars, in fact I hope it isn't related to some "cheap trick" like making every car's rear tires less grippy instead of improvements in weight transfers lol. Well, it doesn't seem like it because they actually behave in a believable manner from what I've seen and you guys reported, not some brutal unexpected loss of the rear (this would have been the case if what they actually did was the "cheap trick"), but who knows lol
) but just about any car that puts power to the rear tires seems to have incredibly sudden snap oversteer at weird times. And I'm talking about cars renowned for their handling, like the E46 M3 and ND MX-5.

The car, In reality, runs with TC. Running its in line with the real car.
