Lightest 17x8 wheel out there?

If you're talking about rolling resistance, you have to consider rotational inertia. Weight that is distributed further away from the axis of rotation will take more energy to spin up.
Therefore, a wheel that weighs more as a whole may actually be lighter to spin up due to the weight distribution.
Think about that in your wheel search. Good luck!

According to this page: http://www.gramlights.com/wheels/57f/index.htm the Gram Lights 57F are 12.3 lbs in 17x7.5" and 13.8 lbs in 17x8.5". Not cheap though...

Gramlights are best light weight wheels here is a pic of the wheels on my car.

Let meunderstand this if weight farthest from the axis of rotation weighs more it will take more energy to spin then I would assume that the wheels, tires, and brakes are farhtest from the axis of rotation. If we assume this fact to be true then how does a heavier wheel spin lighter than a lighter one due to weight ditribution? That to me does not sound logical? I would think that a light er wheel, tire, and brake combo would mean less resistance to the innitial roll out allowing the power in the form of torque to work more efficiantly. I guess I am no engineer but 1+1=2. If there are factors I am not considering then please enlighten me. I just would like to opptimize the power distribution so when I hit the gas I am not wasting anything.

I think TE37 and CE28n are your best bet. I weighed my 18" SSR GT2 and they almost 18lbs per rim. Not exactly what I call light but still pretty good for an 18" rim.
Just to give you an idea....when I had my integra, I went from 17" racing hart T6 (17lbs) to 16" Mugen MF8 (12lbs). All I can say is it made my car response so much better. I don't know about a dramatic increase in accerlation tho but def better response.

If you have access to a set of weights:
Take the short bar used for hand weights, place a 10lb weight on each end, place your hands together in the centre and try spinning it around like a propellor; note the effort needed. Now take a pair of 5lb weights and place them at either end of the long bar you use when you're bench pressing, place your hands in the centre and try spinning this setup at the same speed - you will notice that it takes dramatically more effort to reach that rotation speed, if indeed you succeed. Both setups weigh approximately the same (and you can adjust weights so that they are identical), but the mass distribution is very different. The further away the mass is from the rotational centre, the greater the force needed to change the speed of rotation. It's called Inertia.
There's plenty of people here who can provide a more eloquent explanation, but that's basically what's going on.

By George, I think I've got it. It makes sence now. So it soes not really matter as to the weight of the overall tire it has more to do with the tire and and outside of the wheel weight distribution. Thanks you have helped in my search.

I just saw a pic of the gramlight 57f, sick, they look incrdible and I can get them for only $1599 deivered to my door. Anyone else in to upgrade loks, but more importantly performance.
