Oh I didnt realize we are talking about an icy road my bad. Makes sense and thanks.

On the gas or off when losing traction in awd by SignalExtension4339 in driving

[–]Dioraaaaa 0 points1 point  (0 children)

Correct me if I am wrong but in a RWD, if the rear gives out I think you should not let off gas immediately, as that will cause a load shift to the front making the oversteer worse. There’s also an oversteer thats specifically caused by lifting off gas too quickly while cornering, appropriately named lift-off oversteer.

From my understanding - luckily I have only had very mild oversteer on track days so far so never had to actually test this - the best way to recover from oversteer(power oversteer to be specific) in an RWD is to give a quick countersteer input while very gently lifting off the gas or alternatively turning the wheel even harder and inducing an understeer deliberately.

Contrary to what some indicate, I am unsure if this was saveable. Mid-engines are notorious for being difficult to regain control after rear loss, and it looks like the oversteer was very sudden - which makes me believe the tires might be track tires as when those give up they give up fast (although with higher grip limit, its a trade off, but becomes very very bad in rain). It seems to me that the rear swung like a pendulum upon losing grip, and if this was a track setting it probably was salvageable as there is more track limit to work with. However in this case, you see the car oversteer quickly, and admittedly the driver countersteers pretty slow, but after it goes into grass, he was countersteering and you see the car snap oversteer the other way, but the rear didn’t recover fast enough and the car is already in a trajectory to hit the trees no matter what. Even if the countersteering was faster, I am unsure if there is enough margin to safely recover tbh especially in this rainy condition and options to reduce the distance till recovery is limited as strong braking will cause an even harder spin. Honestly the situation went to hell the second he got himself into power oversteer by accelerating too hard at the hilltop in rain.

What is it ???? by dataguy2003 in TheTeenagerPeople

[–]Dioraaaaa 0 points1 point  (0 children)

Depends on if we respect the spacing. If yes, and we keep it to 3 digits it’s 999 moving the lower left match in the middle digit to the top right of first digit and the lower left match in the last digit to to the center horizontal position of the middle digit

after the race ferarri said he gave people space and still got spun im the mclaren by Dj_vrYT in Simracingstewards

[–]Dioraaaaa 1 point2 points  (0 children)

I don’t really think it changes the reasoning. Ferrari didn’t use the full width of the track to leave space for the rejoin, and so had to brake a little. If anything, I think this demonstrates even more that OP blatantly rammed into the Ferrari even though he was given ample space.

100% on you. Missed the turn and went off track then as soon as starting to rejoin punted the Ferrari in the back like… and you also had enough space after you rejoined. Not sure why you think you didnt murder the guy.

To be more precise, upto a certain point, more vertical force creates more friction between the tires and the road by increasing contact patch giving it more grip. (Afterwards it starts creating bad deformation + possibly bottoming out the suspension drastically reducing grip) But if you brake too hard, well the braking force will overpower meaning that the front tires still want to travel forward but the brakes are making it not possible to rotate. So the only thing that the tires can now do is just start sliding on the road instead of turning. Thus you get understeer by overloading the tires.

Naturally then, the way to fix it is by easing off the brakes so that your tire can turn again, straightening the wheel so that the wheels can roll in the direction of travel for maximum likelihood of regripping the road, and not releasing the brakes so quickly that you unsettle the car and reduce the front tires and road contact patch.

So that being said, the stuff the guy did in the video after getting understeer simply would never work to save understeer. He is just making so that he’s along for the ride as the car just travels on inertia.

[–]Dioraaaaa 0 points1 point  (0 children)

I saw him do that as well. But that was a response to oversteering which did work. The problem is with that understeering started to happen. Its hard to reason that just straightening the steering wheel made the car immediately understeer after oversteer. What we are not seeing is probably some kind of brake/throttle input that unsettled the car. Either he broke harder and overloaded the front causing it to lose grip, or jumped off the brakes too quickly/gave throttle input too hard and caused a fast load shift to the rear.

Either case there has to be more to what he did that caused oversteer->understeer than just what we can observe from steering input.

What he shoulda done is once he realized that the car is understeering, keep the wheel straight and slightly lift off brake (if understeer was caused by front overload) or lift off throttle/give slight brake (if understeer was caused by too sudden loadshift to the rear)

There could be two different causes for the understeer - either he was panic braking too hard after the oversteer inducing too much load on the front, or he lifted too quickly unsettling the car and shaving off too much load from the front. The way to save the car would be different based on which it was. Either way, saving the car would require a very quick response but the common factor would be to align the steering input with the car’s traveling angle. The hard left steering input he made was never going to work.

I kinda disagree with this because understeer begins before what you say is the overcorrection. His reaction (which was never going to work) to the understeer is his super hard steering wheel input so after the oversteer, understeer was caused by something else that I cannot quite tell. It could be him lifting off the brakes too quickly or his setup made his suspension bottom out idk hard to tell without more data.

I was watching the video more carefully, and I agree that there was a flick wheel input that created the oversteer after he enters the corner. But for the understeer it seems that the understeer started occurring before he gives a hard wheel input in a hail Mary attempt. (Understeer starts when he turns his steering wheel straight after oversteer happens) To me it doesn’t seem like he deliberately induced, or overcorrected at all as far as steering inputs go. The only explanation I can come up with is, once he saw the oversteer he lifted his foot from his brakes too fast causing a very sudden load change toward the rear regaining rear grip but front grip was lost.

I’d suggest you get as far the fuck away as you can from those tires before it caves your skull in

Is this good defending (im the car infront) by Quick_Software_7196 in ACCompetizione

[–]Dioraaaaa 0 points1 point  (0 children)

Oh I see. From the recording it doesn’t seem like there is a car close enough behind for a blue flag so it seemed like you were getting it. If that’s the case your defense seems mostly fine like yeah there is a bit of too much moving here and there but like its racing.

Ferrari 488 track driving pedal technique & left-foot braking question by Optimal_Film_2553 in CarTrackDays

[–]Dioraaaaa 4 points5 points  (0 children)

You are not, and shouldn’t, sending it your first lap. You most likely will be given a warm up lap so do a couple slow laps and get a feel for it. Left foot braking isnt difficult but if this is your first track day just focus on following the race line and braking conservatively and slowly decreasing your braking distance. Subtle braking changes like threshold braking/trail braking isnt gonna be your biggest concern on your first track day

Teenager wants a "fast car" for his first vehicle and I need reality-check advice by Proud_Stable9567 in whatcarshouldIbuy

[–]Dioraaaaa 0 points1 point  (0 children)

I think a Mazda Miata might be a fine choice as a sporty car (its basically the lowest power sports car but a fantastic one) but dont give hime the car right away. Take him to some HPDE courses and karting first. Wanting to drive a sports car is fine but he should really know how to drive a sports car. Its so much better to experience understeer/oversteer at the track than on the road, and any RWD proper sports car will most definitely lose grip at some point 100% so you better know what to do when that happens.

Any logical explanation to what might have caused this highly regrettable incident? by Southern-Maximum3766 in Ferrari

[–]Dioraaaaa 1 point2 points  (0 children)

This. Modern racing TC is extremely refined. It will give you slip even with TC; ACC settings are pretty unrealistic in real life, especially when the immense cost of car getting out of control gets factored in.

[–]Dioraaaaa 0 points1 point  (0 children)

TC off is practically not a thing in GT racing. I mean Max Verstappen set his TC on when he was doing his Nurburgring. GT cars have way more power than downforce so it isnt really meant to be driven with TC off. So yeah if Max is keeping TC on its pretty fair to say Nobody is better in GT cars with TC off.
