Does anyone here drive their car lowered on R-SR down springs during the winter? I am from Alberta so we get pretty nasty winters.
Im planning to either run the stock wheels during winter and lowered or go smaller at 17" if that would help.

 

The drop isn't that aggressive, you should be fine.. Got mine done and I am from the north east. Super down is a lot lower

 

A couple winters on downs and no issues.
Also on the 17's now too for winter...also no issues.

 

Awesome thanks guys!
Also Sasnuke, would I have any problems running 20"x9" +38 offset w/ 245/35/20 tires?

 

The rear rims would be ok, but the front might not clear the front calipers depending on the rim design. A small spacer would probably address any clearance issues.
The tire size is going to be an issue.
With my 20x8.5 +35 on the front, plus a 6mm spacer, the 235/30/20 I have would rub on the fender liner at full lock turns.
A 20x9 +38 on the front would be about the same fitment as my fronts, but increasing the tire size to 245/35/20 is definitely going to rub on turns, and not even full lock...and especially if you're turning and going over bumps.
I'm downsizing this summer...I loved the look of the 20's, but not the best for everyday driving.
