I looked into the OME springs. I was thinking the mediums would be the way I'd go, but I'm affraid of being the first guy to try it.
I decided to experiment with the cheapest alternative first (seems to be the most cost effective way of doing things). I've picked up some 1.5" spacers from canadian tire $11.99 each). I'm going to put them under the spring (against the axle) and see what happens. If I get the desired lift without compromising the ride then I'll stick with spacers, otherwise I'll be looking for other options.
