The VDC is a lifesaver guys....I wouldn't recommend disabling it or even turning it off.

VDC is never permenently off even with the button pushed. Only way to disable it for good is removing the VDC fuse. This is useful if you are at the track.

VDC?? whats that LOL

 

You can pull one of the fuses to turn it off, but this also kills the antilock brakes and a few other things. I've seen too many threads of WTF I totaled my car "it just randomly spun out" 90% of them had left their VDC off by accident in the rain. RWD cars are very dangerous in the rain; especially without traction control.

 

This is a noob question, wat does vdc do for your car???? Sorry guys, im still learnin bout car... ;-(

 

cuts off power and brakes the indivdual wheel depending on condition.

 

on rain and wife in car? what if you forget to turn it back on when ur wife in the car and unfortunate thing happens? You will be regret for that. LOL safety first and why would u want it off? So you can burn rubber evertime you take off? If bring to track, u then only need 1 click. I don't think any good point to turn it off permanently unless its a track car.

 

G-Ride it is true that only partial off (personal experienced), brought it to snowy parking lot and drift (ofcourse no cars) and it will still kick in if the wheels spin out too much unless change to higher gears.

 

With the VDC on, in the wet, there is an abundance of wheelspin that is allowed in a straight line. Very surprising. As for leaving it off, for me, it has nothing to do with spinning the wheels from a standstill. It's all about how intrusive the VDC is around corners. In stock form it was too aggressive and would cut power around turns long before the car threatened to slide the rear out. I've tested it on the same turn, on and off, so I know how much adhesion is available without VDC. Having the VDC grab a tire and jerk me from my line was much more distracting and unsettling than getting close to or dancing over the edge of adhesion. I've never been fond of upsetting the balance, while cornering, by stabbing the brakes. If something is needed to correct a bad line, I'll gently reduce throttle or gently apply brakes as needed.

I can't imagine how often it would try to step in now that I have the NISMO sway bars on.

Driving with the VDC on isn't the only way to drive safely. It should never be used as a replacement for common sense and good driving habits. VDC on or off, I'm just not going to be able to convince my body to throw the car into an avoidance move that's going to spin it out. You just can't avoid some things and have to do your best to minimize the impact. If you're going to jerk the wheel enough to put the car into a spin, there's a very good chance that you're going to hit something else, possibly worse, VDC on or not. I've had several close calls over the years, where I missed the collision by 6-12 inches, intentionally. Striving to avoid those by any more distance would have resulted in a spin or put me into more danger. You avoid what you can safely, and then accept that there are collisions you can't avoid. Never do something stupid just because you anticipate that the VDC will save you from yourself.

FWIW, the majority of "I wrecked because VDC was OFF!" posts are made by those who always drive with it on, but they turned it off to have some fun. They have no idea what the real limit is and have been spoiled by having VDC correct their dumb mistakes time after time.

 

leave it on...im a victim of VDC!!!...lol....i lost control tryin' to be speed racer!.....and i know how to drive....(thats what i thought.. )

 

That last part is the key phrase. If you had exercised the restraint that the situation called for, you wouldn't have had a problem.

Out of currisity, what were the circumstances around the VDC-off collision? How old are you and what's your experience with RWD cars?

 

I agree completely. I can't understand why someone would want it off in regular everyday driving.

I found it was mostly unobtrusive even at the weekend track event I attended a month ago.

 

I think it is a little different with the '05+ or OEM19s. I recall some '03 and '04 18"ers saying how their VDC allows some healthy wheelspin on corner exit. Not even close with the '05 6MT! In turns, it jumps in well before the OEM 19's will break loose. You would definately notice this on the track, as it's apparent during spirited driving on the streets.

I can even tell a difference, just starting easily from a standstill, in clutch engagement. With the VDC off, everything seems pretty direct. With the VDC on, the clutch engagement is suddenly a bit more vague. Likewise, things aren't as smooth... ...sort of like the difference between driving with the AC on or off, but maybe not that drastic. It doesn't take more than two first-gear starts for me to realize when I've forgotten to turn it off. For me, it's kind of like everything is wrapped in a sponge with the VDC on. I prefer leaving it off and driving the car with the respect that a heavy, 300HP RWD car deserves.

Believe me, if it wasn't so intrusive I wouldn't notice it so much and would simply leave it on all the time.

 

I have had my car for a year now and I drive w/ VDC On and when I was at the infiniti dealership getting an oil change. He recommended that I turn off VDC and just see how the car handles and he told me not be scared cuz as long as you dont intentionally try to whip your car around corners...then you would be fine, but he suggested that I turn it on when it rains or snows.

So for the past 2 days (no rain), I have been driving w/ VDC off and I love the way how the car feels...it really makes the car even more fun to drive IMO.
