Was looking at 96,98 and 100 RW spurs from Nexus but they are out of stock. I want to get some spurs ordered so I can have them when the car arrives any know where I can get them?
I use the 96 tooth PRS and RW spurs on both my '007 and '008. They are pushing the limit for being able to access the rear motor screw when running 17.5 brushless. You definitely need a ball end wrench to just barely reach the screw. If you go any smaller, you'll need to remove the top decks and layshaft to tighten the rear screw. A couple of other guys running 13.5 and 10.5 opted for the 100 tooth for this reason, since you don't need as crazy of a rollout for those motors compared to a 17.5.
I got mine from Nexus. Try Ashford Hobby or Stormer.
