Carbon Fiber
Wheels? With Magnesium rims. Crazy.
Dymag
Technical Criteria
- Each DYMAG wheel is made up of a Carbon Fibre rim and Magnesium centre.
- The Centre and Magnesium rim are attached via special attachment bolt & sealing system.
- The Centre can be colour coded to match or contrast the vehicle. (Colour Chart)
- Carbon Rims are fabricated using solid metal moulds in a unique Dymag developed process, this ensures:
-continuous close tolerances of accuracy direct from the tooling.
-high quality, durable finish which is resistant to brake dust, salt, ultra violet and corrosion.
- Carbon Fibre in this form is not only very strong, but is also resistant to shock.
- The low weight but high stiffness of carbon Fibre rims produces a very light weight rim to wheel ratio, significantly reducing the moment of inertia and drastically reducing the amount of power required to start, stop, & turn the vehicle.
- The effect of carbon/magnesium wheels when fitted to the car is to reduce the gyroscope effect of the wheel and ultimately producing the following effects:
1. Improved acceleration
2. Improved braking, reduced stopping distance
3. Greater fuel efficiency
4. Lighter, sharper steering
5. Allows for softer damper settings giving more tire contact & therefore better grip.
6. Tire temperatures are more stable.
7. Improved wheel & tire balancing.
8. Reduced rim weight has the effect of at least 5 times the static weight reduction.
Summary
The performance gain achieved by reducing the wheel mass (Un-sprung Mass) can be quantified using a factor of six. This means that to achieve the same performance gain by reducing the body mass, it is necessary to remove six times the wheel weight saving.
Example
A saving of 2Kg Per Wheel x 4 Wheels = Removing 48 Kg from the Bodywork.
In some instances, Dymag’s Carbon Mag wheels have reduced the wheel weight by up to 5Kg / Wheel, which equates to saving 120Kg from the bodywork to get the same performance advantage.

I'm OK with carbon wheels on bikes. Not much weight on the wheels, a few pounds makes a big difference, etc.
On a car, it's retarded. There's a reason you don't see them on race cars; the weight tradeoff isn't worth the risk of what an impact would do to that wheel vs a more traditional rim. You don't see them in places like F1 for a reason.
Yes, they're pimp; yes, they come on the Koenigsegg, yes, they make Porsche and even Subaru fitments, but there is no way I would run on those on a street or track.
Think aobut it......do you want your wheels to be epoxied together with the amount of heat that comes through brake systems?

^+1. Broken rim = grand finale of a fireworks show..... sweet!!! Def. a great looking tire for show but I agree with everyone else.. thats about it. No way I'd trust these for track/street driving.

carbonfiber-to-metal interface = ftl. I guess you won't see a terrible amount of heat difference from the hub to the outr rim areas since we all don't go racing every day, but if you do, the coefficient of thermal expansion mismatch between the carbon fiber and the metal will kill the rim eventually...... Also "Carbon Rims are fabricated using solid metal moulds" is something that every aerospace corp does to lay up C/F tubes, beams, etc but they seemed to have made hogging out metal plates to make a C/F mold into some extra special revolutionary process. .
Just out of curiosity can someone confirm whether or not their equation for reducing unsprung/rotational mass compared to reducing body/chassis weight is accurate or not? If so I'm thinking just going from stock wrx rims to some BBS or comparable rims would be a big weight savings. Would that mean that my friend that just traded out his '04 stockers for some BBS rims removed the equivalent of 192 lbs. of chassis weight (@ 8 lbs less per wheel x 6)?
