you want the best rims and lightest rims go with team dynamics.i have a set on my car ...each rims is 20 pounds lighter than stock rims and omg first gear tachs out quick.be careful though the light rims have a tendacy to jerk the steering wheel out of my hand when power shifting.good luck!
My OZ Superlegerras do the same thing-so much lighter than stock-I feel the lower momentum generated by lighter rims harder to handle because I was not used to it.
Here is a link to some wheel weights by name and size and weight. The Team Dynamics and OZs are nice and light! http://www.wheelweights.net/
