Scott,
Check out this build thread using the same tire and wheel setup that you are asking about. http://www.modelcarsmag.com/forums/index.php?showtopic=83984&hl=
My issue is that I will sit down and find myself just staring at the components and think what needs to be done, what direction should i take and what needs to be done next. Then I put that kit away and pull out another and same process again and again.
My favorite by far is Model Empire in Greenfield, WI. So many categories, knowledge and friendly service and support every time I go there which is 2-3 times per month.
