Went to 7/7 diffs last night and the buggy felt fantastic. Much more controlled and the rear was a bit more locked in on a loose wet track. Now I just need to figure out my rear shock setup. 30wt losi/6x1.2/1 dot springs bounces around a bit too much.
Tried a 17.5 blinky setup too. kimborough spur, AE pads at 69/30 was pretty good and drops right in with no issues, although temps are high.
