After one lap the front tires are definitely colder in T1 than on the outlap. So that could probably explain the better stability, since the fronts grip less than one lap before.
Cool. You seem to know your stuff. I've only done this thing enough to forget how many times I have, but it seems I've been fooled all this time.This can be explained with more balance. We can mess around with balance-affecting suspension settings all day long. R&T drove the car as delivered I assume.
10% difference in maximum lateral grip is very easily explained with front or rear giving up prematurely.

If you want to test, this has my old v7 tires converted in v10

As a sidenote, Singer recommends the AWD option for the 4.0L cars, which suggests 4.0L and RWD is not "comfortable" for most users. I find it funner with less power, myself.
I think it's more a case of it being basically impossible, on road tires, to get a 400hp~ engine to not overpower the trailing arm. It's still manageable, but I bet most 964 owners have never had their car let go simply from power, and AWD could save their neck. Mind you the 993 AWD Singer uses is more oversteery and simple than the 964's AWD, so it'll probably still be fun.
The later Turbos had around 380bhp IIRC, some sources claim 400bhp. So around the same power as the 4.0. I can't remember if 964 Turbos were RWD or AWD: 993 were AWD.
Now consider below is an early Turbo car, with the way more understeery suspension and tire setup than Singer and it still oversteers on power sometimes, with something around 320bhp~ which is claimed for those early Turbo cars. Oh, and these ones also have a 20/100 diff compared to the 40/40 diffs in the C2. I've added range for 20% power and 100% coast for the next Singer build.
I'd be surprised if the later turbo cars didn't let go under throttle. Of course, let's take the worse tires into account, but it's more to illustrate that 70hp~ was enough to make the car oversteer on power given the right circumstance. Singer's 4.0 has 390 - 425bhp, so around 150bhp more than standard, or about 60% more power.
Would there be any demand for the 4.0L AWD version or the 3.8L 300bhp version?
If you're full throttle for any extended period, it really doesn't matter at all. These cars don't really have any true turbo lag like say the 930.
Kilowatts are kilowatts and it doesn't matter how they're generated: apart from turbo pressure not being constant, so I guess you'll have some minute variation IRL, when NA would be smoother.
That's not what "balance" means from a vehicle dynamics perspective, ever.Technically the car would be balanced if it had even slip angles at all times, or more precisely, even force from the axles at all times.
Sure, "balance" means varying degrees of understeer to just about anyone. Which is what we already have: just a bit less than on a stock 964.That's not what "balance" means from a vehicle dynamics perspective, ever.
Anyway, not to play devil's advocate, but the behavior in the Black Cat County videos looks exceedingly unlikely for a production car. Additionally, it looks to behave a good bit differently in the laguna hotlap than in AC.
I can pretty well guarantee the real tires (irrespective of compound/construction) have more than a 1.1% grip difference at nominal loads front to rear (that yours have). ~20% width difference means a lot more than that. For the record, the P13's tires (3% width difference) have a larger grip distribution than that.Sure, "balance" means varying degrees of understeer to just about anyone.

I didn't know leaked footage of the car driving on the slicks I made for it in AC got out. Someone must have access to my HDD. Could you send me that footage so I can compare it to the Laguna Seca video? You know, because it's on slicks in the video and not semis.
I don't know what tire set you're talking about, but I'm going to assume semis. I think so too, which is why I've made the difference larger for the next version. What kind of % split do you think is in the ballpark?I can pretty well guarantee the real tires (irrespective of compound/construction) have more than a 1.1% grip difference at nominal loads front to rear (that yours have). ~20% width difference means a lot more than that.

Could do with losing a bit of the attitude.
Not power oversteer that’s the problem.I don't know what tire set you're talking about, but I'm going to assume semis. I think so too, which is why I've made the difference larger for the next version. What kind of % split do you think is in the ballpark?
I just found it a bit funny how you're comparing a car on semis and a car on slicks as a basis for argument. Most the power-oversteer issues go away if you can't get wheelspin even when you're full throttle with wheel turned. I thought it'd be kind of evident.
I probably should make some tools to generate curves for AC's format. I'm curious, are you using an app to look @ the tire grip or just calculated it?Not power oversteer that’s the problem.
Anyway, it depends. Certainly well upwards of 5%. Refer to the Z06 tires I did with Jason as an extreme example of unequal grip distribution. In any case, I’m still not entirely sure why you use KS load sensitivity as a basis.
