These may already be complete, but I wanted to add my .02 from a Mercedes perspective. Please don't put any reference to SRT or Needswings on the top. Why limit your potential market unless you're going to offer different units to the Mercedes crowd? Mercedes owners want to see AMG on the engine, period. I would assume SRT owners would like it as well.

I would suggest AMG on the top, and Needswings down the side.
