Gotcha, thx. I thought they were netting a little over the advertised. I'm currently at 20.5" on the front shock measurement; so I'll plan for 21.5" for the 3 and 22.5" if I decide to go for the 4.
I'm in the same dilemma as a lot of members have experienced; buying 35s and now wanting 37s. I really need to wait and wear out these BFG and go with 4" and 37s...
