For you mbx-5T owners....what diff fluid are you using

[gtxracer]

Little update...

I've gotten some wheel time on the Mugen ever since I went with truggy as my only class. On small tracks, a smaller car is ideal, 1/8 buggy is tight, truggy is pushing it and I generally don't race on the small tracks anymore.

However, I brought my truggy home with me and the track down here is HUGE. I had the fastest lap time in the first heat of racing yesterday and the truggy did great. It actually felt really good and pretty stable with the way I have it now. I want to get a little more steering so I might go down in fluid up front but I'm not sure what's up there right now. I want to try 10K and see how that does. I could also tear apart the rear and put some 5K in there - opinions? Thoughts?
