I have a much wider set-up that is identical to stock tire diameter. I get more grip and no loss of power due to taller tire. In the viedo they mention they use a taller tire, but don't talk AT ALL about how that effects the result. It's put a ton of misinformation on the boards.

It's true it would have been a better apples to apples comparison if they had mounted 17" wheels/tires of the same diameter, but the difference was still small (less than 2mph at 60) and sometimes taller gearing can help depending on the track (and the car)
But I think this still helps to show that for lower powered cars a wider wheel/tire is
not necessarily going to be faster around a track. In this case the mild extra grip simply couldn't overcome the lack of power this car has for this track. (you would think with extra grip you would gain speed through a corner and actually be faster out of a turn despite the taller gearing but this wasn't the case)
Also wider tires can diminish your road feel, alter the cars balance and willingness to rotate, and affect turn in so for most people who have these cars and will never see a track, wider may not be the best decision and in fact may diminish the 'feel' and 'fun' of driving. One of my previous track cars was a miata and putting huge tires on it really reduced the fun of driving it. It could carry a ton of sped through the corners though.
BTW, in the article they do talk about how the taller diameter and 18" wheels/tires affected acceleration. They may not have addressed this in the video.
