Currently running the standard 750wt Yokomo oil that comes with the kit, and wondering if this does happen to contribute towards my problem, which it may or maynot, is this too light? Running this with 4.5t high torque motor (x11 octa) with no boost and mild turbo, and about -35% expo on the radio to try and control this problem.

So, for modified, I've seen setups with oils 1-5k variants in the rear differential on various med/low grip ashphalt track. For something relatively small, with somewhat small amounts of grip most of the time, what oils would you suggest?

This is reall appreciated guys, so thankyou for spending the time to read this.
Bill.
