I think probably the biggest take away from the misc. threads is the lubrication. The stock mineral based lubricant just can't cut it at the track. New properly cleaned, dried and packed bearings with the EP stuff probably make more difference than which bearing you choose.
Cory, any chance you have one of those bearings on the parts shelf and can look to see if it has any other markings or numbers? Would just be interesting.
One of the other interesting comments was race teams just keeping built up spindles as spares so they can swap at the track. Pop the ball joint, tie rod, 2 strut bolts and slip out the axle... reverse. 5 minute job with the right tools/skills.
Hey Scott, what did you do with your 5x100 spindles?
