If you want the same fender to tire clearance (assuming the same overall sidewall shape), you would have to subtract an additional 12mm from your offset number, meaning you'd have to use a 17mm spacer in the front, and a 32mm spacer in the rear.

The spacer sizes you listed will allow you to use the REs with no issue. They may just not be an aggressive enough fit for your tastes.

Thanks so much... very helpful. I'm more concerned with maintaining the geometry than maintaining the appearance, so I think I'll go with my initial spec here. Plus the fact that I'm already a little skittish with using such an enormous spacer in the rear... adding another 12mm just for looks doesn't seem like such a great idea.

Thanks again!
