Sorex 36's, ok. Oh and whats the internal gear ratio on the pro 4? Or at least what page of this thread is it on?
I was just gonna get the diff for running on the carpet track, I never did too well with a one way in there with my pro 3. Can I get the gear plate at speedtech or tower? Cause those are the places Im going for the other stuff so I'd like to keep it to as few shipping charges as possible
BTW, yeah that backstretch does get awful long with a stock hehe.
