4000q max tire size 17''

[Todd Phenneger]

Antti,
  I agree with you on the camber values and its correlation to
wheel placement.  Obviously the arc of travel will be different.
 But the Shocks 90% of the lowered 4kqs out there run are no
different than stock travel wise.  They have the same
compression limits and the tire will travel just as far up into
the wheel well.
  If the tire rubbing is at the top of the WHeel Arch then
certainly the camber values will be crucial.  HOwever, I am
hearing that they are rubbing on the front of the rear Bumper.
That is closer to the Centerline of the wheel, where camber
changes are not going to be noticed, or if noticable will be a
fraction of the what they are at the top of the wheel.
  Am I missing something
