always do a test fit with clear tape (and stand a car length or 2 away to make sure everything looks proper for normal viewing distance). here the '911S' sits underneath (but doesn't cross) the R and the C above. overall the '911S' is NO MORE then 4+3/4" inches in width. also note that the '911S' is all TOP aligned. in this pic i am also going to re-apply the 'S' in PORSCHE since i screwed it up the first time.
