I actually have some video footage of the race, I'll see if I can post it up somewhere tonight, you can see how the truck ran (and my lousy driving ).

The diff mod seemed to help quite a bit, I may go to a thicker oil yet as it seemed to still wanted to diff out under acceleration and spin out if I got on it just a fraction too quick. I found info on what to use on RCTech, I may try it again and add a little more of the 2000wt diff oil and a little less shock oil. I was def. smoother than the grease. Or I may just go the ball diff route and not have to worry about it.
