Good point (you always seem to drill down to the facts). I never mentioned this thinking it was obvious.

After reading the entire thread again, I believe that his VDC is operating as expected. VDC is not “broken” here.

The initial report does not mention driving the car very hard, but a later post describes much faster driving. Of course, driving the car very hard and pushing it to its limits would certainly entail some slipping, and thus VDC activation.

I doubt very much that the different brands of tires cause this problem. That would only happen if the original tires were worn significantly. However, new tires with a layer of grease and a tendency to slip, would certainly invite VDC activation. We have seen many reports describing this occurrence, and I’ve personally seen this when replacing tires.

I believe this problem-report will go away once the new tires are driven for a short time.

Like I said, nothing new with G35's that all have vdc. Changing the front tires to the same brand/style almost always fixes the problem

Agree. I fail to see a “problem.”

Although that is a thought that the VDC is operating "normal", it is incorrect in this case.

I have done several track events and this did not happen until I replaced the rear tires. I understand what you are saying but the only variable that has changed from one track event to the next is the tires. And yes, the car was driven very hard every time. Believe me, the VDC is not operating "normal". I have had the car 3 years and know how it should and does act.

Believe me, there is a problem. I talked to the dealer today and the service manager checked with his guys in the shop and one of them has said that had seen it before. He was going to call Nissan and see what they had on it. Also, as redlude97 pointed out, there is quite a bit of chatter on G35driver about this very issue. Although no one seems to have a great reason for it happening, it seems that it does happen on occasion.

Now here's the weird part. Last fall I did 2 days at Watkins with the old tires and never had an issue. I probably put 1-2k on them since then and as a matter of fact I did some laps at Watkins with the old tires 2 weeks prior to the new rears without any issues.
Different grip levels and drivin hard on the track.

I think the different grip levels plays a significant part of it. Driving hard on the track really doesn't as the VDC now kicks in just getting on the expressway.

Fronts being 1/2 worn and rears being new can cause slightly more stagger than VDC needs to see. Ive had it happen on stock wheels and on the Volks when switching tires. Get new fronts or wear down the rears lol...
