Snow and PSM

[spud]

First post, so please be gentle.

I've got an 08 C2 with Pirelli snow tires. I live in Ohio and we'll soon get snow and I'm planning on driving it this winter. Is there a consensus of opinion as to using PSM in the snow. Thanks

It's rock solid, especially if you have a 997 C4 like I do. Even on ice, you can pass any SUV on the road at Z-rated speeds in the worst conditions.

You'll have a blast.

Don't forget: it snows in Germany :) One reason the Porsche is an awesome winter car.

I would think snow is exactly where you want PSM to be there to save your a**. Unless you drive on public roads like you are on a track you will have a very hard time getting the PSM to fire on a dry road. I've never been able to do it on a dry road -- or (I may be embarrassed to admit) even in an autocross. Partly that's because I have a C4 and it just doesn't want to let go. Maybe once my PSM actually did fire on some wet leaves on a winding narrow road in the coastal mountains, but I was thinking recovery and didn't have time to look at the instruments to see if the PSM light went on. We don't have snow around here-- I would love to try the PSM on snow. You might find some big snow covered parking lot when it is empty on a Sunday morning and see what happens with and without PSM. Now that would be fun...

Thanks guys. We recently had about three inches of snow and I found a large, empty, untracked parking lot and did some of my own experiments. Without PSM I could do endless donuts and oversteer with just a little too much throttle. With the PSM it would just understeer as the PSM took over. I played too long and it was childish but great fun. I'll go into snow fearlessly with snow tires just so long as it isn't too deep.

Not too fearlessly, I hope. Even with PSM your stopping distance in the snow when hitting the brakes hard will be much much longer than on the dry. So watch those spin-outs of cars right in front of you who don't have PSM...
