With VDC on, is it even possible to lose control of the car?

Once, I was taking a corner in the rain and the back end started to slide. The car automatically braked the outside front wheel to keep the car from losing control. It was very neat to feel it working and there is no way that anyone can perform that type of car control manually as there is no way for a person to selectively apply the brakes to only one wheel.

I guess id have to drive my car in the rain to experience that LOL, I did not know that, but good to know.

Nope, the car only has 13xx km on it.

Believe it or not, I am actually capable of gaining control back...under settings where I expect it to happen.

What I am worried about is having the car slip at times and places where I least expect it and catches me off guard.

I downshifted to 3rd today, braked a little past the pedestrian line and then took a hard left today with a Pontiac tailing me and the green left turn arrow was turning yellow. I heard the tires screech at that point, I was going pretty fast, I just don't know what the limit is before the car will spin out.

If the roads are dry, and your tires are not bald, and you aren't doing 70MPH it is pretty hard to totally lose control with VDC on. It might be possible depending on the road but you would have to be doing something incredibly stupid. The whole point of VDC is to keep you from being an idiot once you start to slip.

Knowing this statement to be true, I was still amazed at how true it was when I drove my Z on the track for the first time. That being said, I don't mind a little wheel spin now and again

and I leave VDC off for the most part. The only time it kicks in is the rare occasion when I have forgotten to turn it off.

In the rain I always leave VDC on, and I have had several incidents where I lost traction, whether due to road condition, other drivers, or even that one time where I got stuck out in the rain on damn near bald tires on my way to Discount Tire. VDC and ABLS are doing their best, but they can only correct for so much. There is no substitute for experience - I have practiced evasive maneuvers in huge empty parking lots during the rain more than once. You don't want that first big mistake to be too big.

BTW, I believe ABLS (IIRC, Active Limited Braking System) is still active even with VDC off. It can easily be overcome with medium throttle.

It doesn't have to flash to cut in and to be working. Don't judge your driving on whether it's blinking at you.

VDC off is completely different. If you don't drive with it off, you don't know.

but the OP was with VDC on can you lose control....if there is oil or fluids on the roads, VDC will not help! Like what happened to me today!!!
Broken bus caused me to lose control

Is it caused by the base tires not being good (wide) enough? When I put on my Volks I'm going with 305s at the rear, I'm suspecting this would not happen?

How hard could I be accelerating when I'm keeping it under 4k rpm?

Idk what tires are on the base but I never had that problem on my nismo. Even with the stock tires.

I run a 295 pilot supersport on the rear now and i definitely dont get that

I do drive with it off sometimes but I don't feel a need to since it never cuts in unless I **** up or roads suck.

I think I know what VDC cutting in feels like, I have done canyon runs with it off and on, no difference in time, no difference in experience(my first canyon run with VDC off in fact was an accident, I forgot I turned it off and I did the run thinking it was on the entire time)

Can your experience brake each wheel individually…??
