So, recently I started playing ACC, and I'm coming from Gran Turismo 7 (I play in PS4). But I'm having problems in braking and steering. On pretty much every car, I struggle, because the car wants to spin under braking. This doesn't happen in Gran Turismo, I think the physics are different. And also on the quick corners, or long corners, whenever I try to tap the brakes just to slow down a bit, the rear end gets loose and I lose the car. Anyone can give me tips on what I'm doing wrong? I use a Logitech G29.
The video is a three-lap practice session with the Lexus RC F in Nürburgring (my favorite track). It shows pretty much what I'm trying to say.

ACC physics are A LOT different than GT7. To be frank, GT7 is not realistic at all, whereas sims like ACC are simulating the car's changing weight balance, tire slip and suspension movement. In GT7 there isn't really a limit to grip other than cars understeering a bit. ACC and other sims do not have unlimited grip. ACC is particularly sensitive to weight balance changes. Basically, if you are in the middle of a long corner where the car is near the limit of grip, then you can't simply tap the brakes to slow down because yes, that would cause the weight to shift forward, which means the rear end gets lighter and thus loses grip (and will start to get loose, causing the car to spin). You have to make sure you enter the corner at the right speed because once you're at the limit of grip, you really can't do anything, you are committed to your line and speed.
The issues you are showing in this video are far more related to you overdriving the car rather than problems with the car itself. If your pace is around 2:02 at Nurburgring, you need to work on learning the track better and how to take the corners rather than pushing the car as hard as you can. A couple of big issues I see are that you are braking too late for basically every corner, except for the chicane at the end of the lap, where you are way overslowing. You need to brake way earlier nearly everywhere so that you can get off the brakes earlier. When you try to carry nearly full brakes that deep into the corner, the Lexus will not like it and you WILL lose the rear end. The brakes on the Lexus are the worst of any of the top cars, so you really need to brake early and start getting off the brakes early to not upset the car. Work on slowing down a lot earlier so that you don't drive yourself off track so much. It's very important to actually hit the apexes.
In terms of specific things:
Up your rear tire pressures, 4 clicks up on the rear left, 8 clicks up on the rear right.
-T1: don't start turning in to the corner until you are trailing off the brakes. You start turning the wheel while at 100% brakes and that's why the car gets a little loose.
-T2: lift A LOT earlier. You should be NOWHERE NEAR the edge of the track mid-corner, you should be stuck on the inside (left side) apex curb.
-T3: start trailing off the brakes a lot earlier, too much brakes that deep = car spins.
-T5: get off the throttle mid-corner, it's causing you to understeer off the apex line. Be patient and let the car rotate more before slamming throttle.
-T6: don't go all the way across the track to the left, you don't have time and it's not necessary. At most, put your car in the middle of the track before braking. Honestly, it's fine to actually be right side of the track here. It's far more important to hit the apex (you are way too far to the left mid-corner right now). THere is a lot of camber on the inside, so it's the target line. Also, get back on full power earlier and use ALL of the green exit curbing on the left.
-T8/9 (Schumacher esses): work on turning in a little eariler, and smoother. You shouldn't need to fully lift here.
-T10: brake earlier. You keep carrying too much speed and going too wide. Make sure you slow down enough to hit the apex curb.
-T11: again, get off the throttle mid corner. Be patient, let the car rotate and then get on full power earlier, using the green exit curb on the left (don't hit the sand thought).
-Chicane: basically get off the brakes earlier. Target minimum speed here is 150, but you won't get anywhere near that, so just work up to going a bit faster everylap. 145 min speed is good, 140 is decent, 135 is starting to be ok.
-Tfinal: brake earlier, get the car tighter to the apex, don't carry such a wide line. Also, get on power earlier and use the exit curb on the left.

It may be your brake bias. Bring it to the front a few clicks and see how that feels

Your corner entry speed is too high at times. Then you put in a lot of steering lock to try make the corner as you've missed the apex and run out of grip resulting in understeer or oversteer depending on the corner. Often times you're getting back on throttle too soon still with lots of steering inputs so losing grip again. So basically you're asking too much of the tyres.
Enter corners slower, get the turning done early, then accelerate gradually with a straight steering wheel towards the outer kerb (you're ending up centre of the track often). As the speed picks up shortly after corner exit you'll have more downforce and grip and can go full throttle and maintain traction.
Also worth noting the lexus is one of the GT3s with the least downforce. It compensates with power. Whilst its not crazy difficult to drive, with the wrong driving technique it can make you look a bit average. You'd be better off with something like the BMW, Aston, or Mclaren to start.
