This is going to be my first winter in my MR. I just got some stock Evo wheels and I'm planning on ordering some LM-22 for them. Has anyone noticed any benenfit from using the Snow setting on their ACD? Everything I have read from test drives say they noticed no difference when testing on the street. So far I've just left it on Tarmac.

 

in the really slippery stuff switching the diff to "snow" keeps the car from power on oversteering in a corner. Granted it does (as expected) make the car tend to understeer.

 

I dont see a difference when it rains and I change the mode to gravel. AWD is AWD IMO. When it snows I will definetly use the snow mode though, just caus its there.

 

yeah i'd like to know how that snow mode works on the acd... not sure if i'll ever use it though.

 

everyone make a road trip to canada.......snow trip!

 

I would worry less about the ACD and more about what kind of tires you have on your car. Advans are no good in the snow. I would be scared to drive mine in conditions like that! It would also break my heart to see salt caked on its sides.

 

go for the blizzaks if your goin to get winter tires.....might be expensive but they are very good

 

That's why I'm getting the winter tire/rim set up for the MR. I don't have the luxury of having a winter only car, although I will also be driving my wife's Forester XT with WS50 blizzaks. I'm wondering about using the snow setting in addition to the winter tires. I don't think I'll have any problem getting around this winter, but I haven't trying changing my ACD settings yet.

 

if you're pushing the car on a wet road you can definitely feel the difference in the 3 settings. On snow there is a noticable difference even when you're not pushing that hard. You won't hurt the car by running in snow mode on a dry road, it will just not optimize the center diff lockup rate for the current driving conditions.

 

wish i had different setting for my car... go FWD! haha

 

Many may have or should have said search, but I am nice - Ill explain some. Greg K stated it well in his first post. But here is the breakdown: (These are the theoretical numbers, our cars can never go all FWD, the rear will always have some split of the power, but the computer ACD thinks like this)

Setting F R
Tarmac - 50/50
Gravel - 75/25
Snow - 100/00

The settings do work, I have have had my Evo for a winter now, and on the Advans at that (yes I am crazy, and I am not doing that again - all-season tires this round). But the car will behave closer to a FWD in the snow setting when you are in snow. Makes it easier to drive around, but it will understeer more.

 

I got a sweet set up from tires.com. Enkei rims and hankook performance winter tires for $892 shipped. Im putting them on this weekend.

 

Good for you....now, I am not going to flame you. But what does this have to do with ACD and snow?

Stick to the topic.

 

To be clear, the Evo is always 50/50 no matter what setting you choose. The different settings just determine when the diff locks.

 

Well other members were talking about winter driving conditions. Chill dude
