I'm no expert, but I've done a few autocrosses, mtn runs, etc over the years...in lots of different cars. Sometimes on street tires, sometimes on slicks, etc. I've pushed every car I've owned (and several I didn't own) to their handling limits, and beyond. So I like to think that I have a decent idea of how good or bad the handling of a car is. That being said....with the right suspension/tire setup, the S13 handles great. And they do in fact have very close to 50/50 weight dist with the SR installed.
