I was just wondering what the differences of those three versions are.
II seems a bit wider than I or III and also is a bit more "rounded" at the rear. If anyone can tell me the differences or at least the increase in width i would be so thankful.

 

From what I've seen the round rear fenders are the only thing. The front fenders are the exact same as the ad gt 1 kit

 

**correction,after reading the description on reamemiya.us website it appears the ad-gt II kit rear fenders are 15mm wider than the version I kit.
