I'm about to buy some new 3.73 gears and decided that I should rebuild the rest while I'm in there. I was researching the alternate disk stacking method here http://www.corral.net/tech/drivetrain/gears.html and was wondering if anyone who's done it ran into durability issues? Also, I read somewhere on here that removing the S-spring will yield better cornering? What purpose does the s-spring serve and will leaving it out cause any side-effects?
