I agree with what was said above. Go with the stock setup and make sure your diffs are set properly!!. I had a pro2 a few years back and I loved it. I ran very close to the stock steup. I use to whip many street weapons with it. The only reason I got rid of it was it was a hassle to work on. Especially the diffs to get to them. In my opion I would still take the pro2 over the pro3
