THANK YOU, GUYS! in response to your question, Christian, I wish I had a photo of the kit wheels next to the Tamiya ones. The kit ones were too small diameter, if I remember right, but the thing I do remember is that the breather holes were too small, and THICK looking. sure I coulda drilled the holes out bigger, but why do that when I had an extra set of Tamiya Countach wheels! Hope this helps you out -thanx for the question!
