I want to make my 2005 more capable in deeper snow. Any suggestions on how to increase both the front and rear ride height? What is a reasonable amount to increase? 1in?

 

Probably the best and easiest way to make it more capable in deep snow is to put a set of new winter tires on it; not only will this course of action cost far-FAR less than increasing the ride height, it will also yield a much more capable car.

 

X2 on the tires.

What tires do you have now?
How deep are we talking here?

You'll upset the camber arcs.

Either trick air suspension or easie, an MDX.
