I went to 6ish (mixed some 7 and 5) in the front just recently and it gives a little better rebound to gunning it out of a turn.
I've done some reading on a couple different forums and looks like 5/5/3 is a fairly common set up. Seems like it's a step in the right direction for our tracks here, hopefully tearing the diffs and changing will not be a waste of time ?
Thanks
I retired from RC, now life is all about guns and long range shooting.
