Hi, well I recently got a hyper7 and am wondering what diff oil I should put in the front center and rear diffs? I understand that will depend on the track I use it at so here is my question, how do different weight oils affect my buggies handling? I've heard a good setup is 4000 in the front, 10000 in the center, and 1000 in the back, could someone please explain what these different weights do and what more in the front versus the back means? What about the center diff? How does that affect handling?thanks guys
