Smaller rim = less unsprung weight, less inertia, lighter tires.Not sure if that is true..
Stability? Small rims don't mean less in width if that is what your referring to.Jup its mostly for the bling, but what about stability issues?
lighter is the main key for me
ps: You don't have to buy a CR-Z for its performance
im guessing 45... typical honda... unless ur talkin about an s2k... then its a little different lol but thats besides the point..Anyone know the offset of the 16inch and 17inch?
