I want more torque! Carbon wheels?

Dymag makes true carbon fiber rims, not overlaid steel. I don't know pricing, but I know their 18's weigh around 14lbs. They're kind of ugly though, I'm not a big fan. System01 used to make carbon fiber wrapped wheels, at around $200 a wheel IIRC, but I don't think they're around anymore. "Carbon fiber" car rims are pretty scarce. There's too much R&R that goes into making a car wheel out of C/F, so that puts off a lot of companies. The price of carbon fiber also fluctuates greatly, especially as of late with Airbus, Boeing, and the US military buying up a bunch of it, so I would imagine that advertising such rims at a set price for any amount of time would be rather hard.
Looking at the 360Forged rims, they are very nice but as you pointed out, yes, they are just a carbon overlay on top of an aluminum/steel substrate.

Carbon wheels should only be used on a track, hit one pavement or mount one kerb wrongly, it will fracture or crack ur wheel and demolish ur wallet.
They wil increase ur HP and torque readings on a dyno and u will prob feel a difference driving it too. I race bikes and just putting different weight tyres on bikes changes HP and torque readings.
But I would definately restrict use of CF wheels to the track only!

Nicely put!

I work in the aerospace composites business as a Mech Engr / Program Manager and everything you said is 100% correct. For the past 3 years our company has looked numerous times at making 100% carbon fiber wheels and there is a TON of risk and liability involved with it. Too much to make it really worthwhile right now. While Dymag has a carbon rim, it's not ALLl carbon. only the spokes and hub secton are carbon. The rim portion is still metallic. While it's not a 100% all carbon rim, for a number of reasons, their approach is very practical when compared to an all carbon design.
Looking at the 360Forged rims, they are very nice but as you pointed out, yes, they are just a carbon overlay on top of an aluminum/steel substrate.

and in these pics, they don't look half bad on the eclipse here

Actually, it's the other way around.. The rim is carbon fiber and the spokes are magnesium > http://www.dymag.com/index2_e.html
I don't know why I was thinking that they were the other way around for some reason. WTF? Thanks for catching that.
