They look really sharp on there man! Watch out for people trying to steal them! 22s look nice on Lightnings. Those 22s roll out to pretty much the same as your 18s?
Double the weight... or pretty close to it... I don't remember what a stock wheel weighs. But the tire/rim combo weighs right at 80 lbs. And I think the stock wheel/tire combo was around 42 lbs?
But I put down 450/570 on the dyno with these so I am pretty content for now. Now being the key word.
