Your best bet would be to go ahead and commit to full disc all around. This will save you some trouble down the road, if and when you decide to go with a more aggressive brake setup.
If you are interested, I have the rear axles, and front and rear calipers and rotors off of my sn95. PM me or just send me an email,

Sn95 spindles would be the only thing to run down.
