Today, I ran it in the stock class and it was much quieter! I think that the main problem is that the stock and probably Exotek covers simply aren't deep enough and the spur gear basically comes into contact slightly while running the car and causes the contact/rubbing that makes that annoying vibrating noise!
Since I am running the exotek slipper eliminator I decided to slightly sand down the Robinson Racing spur gear a bit with some sandpaper on a FLAT Surface with like 120 Grit. I think it helped quite a bit to silence the tranny like it should be. Not sure, but this might even help with a slipper. However don't remove too much and sacrifice the pads ability to remain in secure engagement with the spur! Basically the material only needs to come off of the Outer edge closest to the cover obviously!
I think it quieted things down for me and interested if anyone else does this if it quiets down their car as well!
