Fran,
I've set the shims almost as per the manual - the only deviation being that on the rear heim i have moved one shim from rear to front. I did this to get a caster of 5 deg - would this make such a difference ?
As for the rocker, the RH side is as far back as possible, part of the front lip has been removed to give extra adjustment.
I removed the spring from the shock and set my ride height to 4.5 inches. Am i missing something else ?
I'm in work at the momnent but will post a pic if this helps. What sort of gap would you expect between tyre and rocker/front clip at it's smallest point ?
