i tried the barry baker setup last night and found the rear to be very loose , so i stood the shocks up a bit more (like u mention) and this did help a little , also put .75 washers under the pivot blocks at the back and 1.5 at the front (both of these on the rear) to create some anti-dive and this also helped too but still felt kinda loose at the rear
thanks for the help so far
maybe the problem is too much grip at the front ???
