Hey Jamie, The Carbon wheels look awesome and I hear you on the expected stiffness. One thing that surprises me is the weight. I would have expected them to be much lighter than 19 and 20 lbs. Thats heavier than a lot of the forged wheels, right?

Those Carbon Wheels are sick

Robert Linton

While I like the concept of carbon fiber wheels, several items:

1. In general, I am not overly fond of the current design of the Carbon Revolution wheels and that, currently, only one design is offered by Carbon Revolution (this, however, is personal preference only).

2. Are these first generation carbon wheels actually considerably lighter than, e.g., BBS forged magnesium wheels?;

3. While additional stiffness is certainly a plus in some operating conditions, in others it can be a minus.

4. My understanding is that, given the temperature tolerances of resin systems, if the spokes are not coated (i.e., as I believe the Carbon Revolution ones are in OE Ford applications), or have a heat shield protecting the spokes (i.e., as the first generation Porsche carbon fiber wheels for the Turbo) there could be heat issues in extreme track conditions.

5. I wonder as to how long various coatings last and the cost.

6. I believe that, given present material limitations, a wheel that has a carbon fiber barrel and magnesium spokes might be a better answer in several regards.

Not sure if they're heavier than a lot of forged, wheels, but the important thing is the strength/stiffness of the wheel at that weight. If taken to an extreme a forged wheel at extreme lightness wouldn't support the weight of the car and would bend as soon as you put the car on the ground. This is the part that I was intrigued by. Most of the wheel industry and most consumers hear "light weight" and think better. And in some cases that's true, but reducing weight wantonly has a cost. That cost is typically strength...

Take a bit of time and read through this...

cheers!

1. I agree, but on the car they look pretty good...
2. The Carbon Rev wheels are 10 years on the market and are now on the Ford GT, Ford GT350R and the Ferrari 488 Pista.
3. Keeping suspension geometry the same during cornering to me is a good thing and will allow less static camber, allowing more precise suspension setup, better tire wear and better braking and accelerative grip.
4. The wheels are ceramic coated on the interior.
5. Wheels have 2 year warranty and we'll see how it goes. This is why I buy and try before I sell...
6. When you make them, give me a call if the price is reasonable I'll try those too...

Thank you but have no intention whatsoever of making wheels.

Thanks Jamie, agree on the sacrifice of going to light and losing strength/stiffness. Keep up the awesome research

First reports:

Car isn't any louder to drive going all solid, the 991 chassis is quite amenable to solid bushings, only the slightest click when going from reverse to forward. Carbon Revolution wheels are quieter on the highway, and the AP Radical Brake package works flawlessly. Won't be able to give a full report until the next track day, which hopefully will be soon!
