Now for the Front Tires trying to run 28mm on the front. Tamiya did not think to well for the use of foams. I think the Kingpin Ball stud on top does not go down far enough. I see almost a 1mm gap as it seats on the steering knuckle before the C Hub. Don't keep on tightening or you will strip out the threads in the plastic. To eliminate the ball cups from rubbing, just chop their heads off a little. See below:



With the 28mm Speedmind Foam installed, it's close but not rubbing! The wheels spin freely. This should be the case with most 28mm foam tires unless they change the wheel diameter on you to be a bit smaller.



Hope these pics help. Any suggestions or concerns guys?
