If not just get the hpi rear solid diff and you just put it in the front. Solid diffs work well in low-mid traction situations and on tighter / smaller courses. Ive been running a solid for awhile now. I think its a good option and its ZERO maintenance as well it wont change from day to day or if the temperature changes.
