on a recent trip to the streets of willow, i turned off mdm and loved it. i was putting more power down out of the tight corners and the car seemed to rotate easier. it only took me two laps to put it into the dirt. i'm not ready to turn it off every time. i guess what i'm trying to say is that although i agree that sticky tires can mask mistakes, mdm will still let you know most of the time.
That is too funny- pretty much did the same thing. The first time I went DSC off, I made it almost a full session thinking "I have this figured out". Which is just about the same time I man-handled the throttle and ended up in the grass at VIR.

What R-comps do is mask the mistakes that will ultimately lead you to exceed the limit of grip and lose control of the car at a higher rate of speed. This is why, my opinion, you see more offs that result in a crash in advanced groups. With an R-comp...you're likely going +10mph faster off track vs those with street tires. So you go off quicker, further and more likely to hit something. R-comps tend to snap vs progressively squeal and lose grip so it is much more difficult to regain control...so I think there is a lower save % as well.

I also disagree with using MDM as a gauge of your driving. There are a couple of common stages for most drivers. One of them is learning to control the rear axle. Unlike the front wheels...the only way to really know what is going on with the rear axle is through the seat. MDM numbs that sensation since it intervenes when it senses slip angle. Good drivers know how to maintain some slip angle in the tires. Even worse...a stock E9X M3 is likely one of the faster cars in any group. So you slaughter the field because of the car (with MDM) and move into advanced. Then you realize that you need to turn DSC off but now you are going much faster with a lot more risk and a certain expectation that comes with most advanced groups.

I would never tell a student to turn off DSC due to liability for the DE org. If things like lawyers and lack of personal accountability didn't exist...I'd tell the student to turn that sh*t off.

I lived this mistake of driving with DSC on in my 330Ci...luckily nothing bad happened but you really are missing out on 50% of the capabilities of this car by driving with MDM on.

In the end...turn DSC off from the start and drive slow.


Sage advice. It's why I worked my way up to turning DSC off while autocrossing so I could learn the car's limits at a lower speed and in a safer environment. As it is, I still don't disable DSC if I'm at an unfamiliar track. I find Euro MDM to be fairly forgiving, but what troubles me is that I know it's doing things without flashing the light/notifying me.

Agree that those running MDM cannot judge their driving. But students get too far down the path with nannies and then freeze when they turn them off. If you cannot feel the back end moving or the whole car slipping, slow down until you can. I have uber grip on R7s but when I screw up, they are completely unforgiving. The grip they give can almost be unsettling unless you are confident in controlling your car.

Auto cross with DSC off is so different than being on track with DSC off that I cannot see any comparison. When you are on the gas flat out at 90mph at apex with the car moving around, that is nothing like auto cross.

2011 or 2012 date code. I'll have to verify they have been in a shipping box. Approx 50% life left. No separation or any concern like that. Really just looking to clear my garage space. Left over because I corded two and switched to slicks so these never got used.
Just make me an offer. Keep in mind shipping is pricey so local (to CT/NYC) is ideal.

master (or just get good at drifting, saving, etc) and the side effect of that will be lower lap times due to confidence in that you know how to save that shit when the car is sliding around.

just spend some time in a slower run group than usual (if you have advanced too much already), create some space, pick some safe corners, crank the wheel and hammer the throttle. you'll get used to it quick.

Just be sure you check with the event organizer first, ones like NCRC will give you the rest of the day off for drifting.

DSC off toward the end of intermediate or early in advanced run groups. The majority of times that I've experienced oversteer has involved not getting into the throttle early enough.

Now back on topic - where are the good deals on NT-01s now?

I'm missing your reference, but I was planning on talking to you about what tires you've been running - Hoosiers I think. At this point, I'd like something that lasts at least 5-6 days. Any thoughts about Hankook TDs or BFGR1s?
