My SC10 got an intermittent click. Basically, under heavy throttle, I could hear it skipping gears. So, as per the supplemental instructions, I installed the additional shims. The click is gone, but before I get too far, I wanted to talk about diff fluid.

Now I've read where people are running anywhere from 20 wt shock oil, up to 30,000 wt diff lube. I have lots of different shock oils, ranging from 20 wt on up to 50 wt. I also have some losi 2k, 5k, and 7k diff fluid. Initially, I started to put 5K in it, but I read that dang near turns it into a locked diff. I still want good turn in, just more stability while accelerating. So I decided to go with the 2K, and I'm glad I did. It almost felt like too much when I was just diffing it in my hand. But after installing it, it seems about "right". I'm still running the stock tires and setup. I want to see what this change by itself does first. I plan to test soon, and will report back what I find.

What has been you guy's experience with diff fluid in the SC10? I've been racing 8th scale for several years now, and am familiar with using the various viscosities to tune the handling. But this is a weird critter being that it's 2WD...
