I used the handy search tool and found this topic! I was rubbing the shield after I installed my 33s. I turned the stops out a bit and now I'm not rubbing anymore. Worked great.

Here's some additional info:

lock nut - 22mm deep socket
steering stop bolt - 14mm
steering stop bolt cap - 20mm
steering stop bolt cap part # - 40039-2S610

You can adjust the steering stop bolt w/o taking the cap off if the bolt isn't too rusted/dirty. If it is dirty, your're going to have to PB Blaster it and pull the cap off b/c it will just spin and/or crack (like 3 of the 4 did for me). I used a claw hammer and pliers to remove the cap. Then a rubber mallet to tap the new caps on.
