On a side note on this, I looked at another racer's truck at the track this past weekend. His was the same as mine, tires don't spin freely once slipper spring is tightened. He was given his truck by a professional racer too, so I'm sure it was built correctly. So this may be nothing, but I'm going to keep checking stuff till I'm satisfied, like the pulley tonight.
Snaf,
I was reshimming my front diff last night and was thinking of you. lol. When I work on the drive line, I check for binding every step of the way. I think you said the rear is binding. I checked my front and it was free rolling. But I remembered something while I was checking it. The tranny screws should have a washer on them to limit how far they go in. If they go too far they will rub on the pulley or other near by moving parts. I will be taking off my rear pulley when I install my exotek clutch locker and I will see if mine was like yours. In the general case, when ever you build a car, always check every moving part for smoothness all the way through the build. Hinge pins, shocks, tranny and etc. This is why I hate buying used cars. I have no idea what yahoo stuff the previous owner did to the car. I always end up tearing the used car down and fixing everything they did wrong. Anyway, check to make sure the tranny screws dont extrend past flush on the motor plate.
