thx john, sounds really cool!
I have found a strange thing with these z8's my gas mileage has been 49 with the d205 then 50 with the sport demon. now all of a sudden up to 56mpg with the z8's! can the diameter of these tires really be that different? and oddly, rpm/speed seems exactly the same. so, what's going on here?
