I didn’t say that’s how it works in real life.
I said that’s how it works in the game.

I thought it would induce understeer. More weight on the back=less grip at the front?

You have to calculate inertia when going around a corner. Initially you may be right, for a lap or 2. Then as the tank empties, the fuel will slosh around under higher g-forces (cornering) so now that fuel weight isn’t just in the rear, it’s in either corner of the tank, changing where the weight sits in relation of the centerline of the car. As that fuel moves to one side, that inertia causes a shift of weight position and can cause a car with less than racing tires to shift oddly when cornering. Racing car’s fuel cells tend to be smaller unless the car is prepped for endurance. This keeps the moving of fuel limited to a smaller space.

Are you playing with a wheel? What track are you driving on? I just tried the C8 Z06 around Suzuka and I found nothing wrong for 8 laps. I’m on a controller, sim steering, no assists. It did slide a bit once when I went off line on spoon curve, but it was balanced the rest of the time.
I just finished the C8 Builder Cup Event today. Not sure if I was in the Z06, but the one I was in was… floppy. It really wanted to come off the ground on one side or the other. This didn’t bother me for the most part.
I also switched it to Sport difficulty for a bit to test out the overhyped fuel setting. It didn’t really make a noticeable difference until the fuel actually ran out, at which point it had a major negative impact. It did that shortly after 1 lap despite the estimated laps going in being 4 or 5. So, definitely not worth the hassle.
Hmmm, I’ll have to try it on different tracks, thank you.
Just tried the Z06 around Maple Valley, Watkins Glen, and Spa. Feels planted at all times. Set times at Maple Valley comparable to the 991.2 GT3 RS I tested at the end of last week.
There has to be a bug somewhere, mine is understeery.
Ran the 2019 GT3 RS and the Z06 at Maple Valley as well. For me, both were at 1:38.XX with the GT3 slightly faster (by about 3 tenths). Z06 was typical MR setup, understeer. GT3 was throttle dependent (as was discussed earlier). Point being that they have programmed the modern 911s based off of early reputation more than actual numbers.
What was worse was the Ferrari 812 Superfast. That thing hates being driven…I couldn’t even get a clean lap in without being much slower. If it was stable, it would walk both the other two…
Yeah, my deltas were similar. The GT3 RS was slightly faster (1:42 something iirc for the 3RS and 1:43 something for the vette). Must be a glitch @Clutch2009 is experiencing which sucks. I’ll try the 812 when I get time. Hopefully the physics on my end aren’t buggy, but I doubt it. I really need to buy these cars, test drive in free play levels cars to where I want them fast 
.
I just ran them in rivals, much easier than fuddling with the free race setup. I will say the GT3 RS allowed me to be slightly faster than Jezza in a stock Lambo (not sure which one he was driving).
Who is Jezza?
A person from the forums that typically runs the Rivals events in FH5. Fast person in general.
Just pulled the #73 2018 GT3 RSR into S class (ballast is so much fun) and ran a 1:32.376 at Maple Valley full. Planted as ever, not one slip up. Had tier 2 ballast, breaks, and the only width upgrades on front and rear. Drove like it should.
I wasn’t sure if I was in the Z06, and it turns out I wasn’t. I was in the 2020 Stingray coupe. When I hit some curbs I was doing stunt driving.
Which is strange, both cars run the same platform though the Stingray should be softer, not harder. If anything it should be more understeery than the Z06.
Oh okay, I have yet to open up FH5 after pre-ordering it lol. I was looking for him on YouTube to no avail.
I managed a clean lap in the 812. 142.465 which is quicker than my GT3 RS time I believe. It’s a rocket ship that’s too fast for its brakes. I was careful in the twisty parts, but when I got to put my foot down, I’m sure that’s where I made up time. Just had to be prepared to brake because corners come at you faster than in the Porsche and the Corvette.
Ran a 135.3 in the #73 911 GT3 R with extra light ballast and wider tires at all 4 corners. Very fun, I’ve driven it before and really enjoyed it, quick steering, and very planted.
I only drove it around Maple valley, the car is twitchy at speed when the fuel runs low and the track is rubbered in. Other than that I tried using kerbs, and nothing. I’ll try it on more tracks tomorrow.

I ran the Stingray at Spa and it was just as pushy as the Z06. Curbs in this game are hit or miss, some allow you to really abuse the apex, others will send you off the track in a cloud of smoke.

Could this understeer issue be something to do with the speed limited steering Forza built in? It’s like they have a predetermined speed you can take a corner and anything faster the car just won’t turn at all. You can literally see the wheel jump like an additional 20deg when you finally hit the speed Forza says ok you can turn now. Check the cockpit view and watch the wheel when you are experiencing understeer and watch what happens when it “hooks” and allows you to turn. I feel like this is why it’s either under or over steer and never feels balanced unless you take corners rather slow to what they should be.
In AC for example you can always turn the wheel but can experience true understeer vs what in Forza seems to be like they are trying to simulate understeer by limiting the steer angle. I dunno. It’s weird and not a fan of whatever it is that’s happening.
It does it under normal and simulation steering on controller btw.

Part of the problem with Forza’s understeer tendency is that it’s not progressive at all. Understeer is being treated as a total negative but it is not necessarily a negative trait in a car/tune. In a real car, you will feel understeer introduced as a gradient whereas in FM, it’s essentially off or on. The inability to play with the progression is what makes this current form of understeer so unworkable.

That’s a good way to describe it, like flipping an on/off understeer switch.
It’s like how you said, the cars are essentially on a knife edge of understeer and oversteer. Finding the balance between those two extremes requires fairly significant tuning away from stock.
It’s fairly annoying that tuning almost acts as a response to poor handling as opposed to focusing strengths on a circuit layout basis.
