Oakley is just a conduit for these wheels.
They are Dymag wheels. Not made by Oakley.
The eleven spoke design is not available in the USA.

They are beautiful and outrageously great wheels. I have them on my 997 GT3 and absolutely love them. They truly perform.

Cheers, GT3Ranger

On the last picture of the Red GT2 (showing the rear wheel), they seem to have run that wheel into a curb! It has fresh scratches on both the spoke and the tire. LOL

Have to be careful with those magnesium wheels, and making impact. Magnesium likes to burn.

BTW I just happened to read the link supplied about the Oakley Design products and specifically the Dymag CF wheels.

Interestingly they described the improved acceleration and go on to state a claimed power gain of 42 bhp in the 996 GT3RS.
I find this unbelieveable and more specifically not true.

This was tested with my 997 GT3 with Champion Motorsport and with the Dymag US sales rep in presence.
My car was dyno'ed with HRE 890R's and promptly turnaround and re-dyno'ed with the Dymags. RESULT there was ZERO rwhp.
This was repeated again and the same result, ZERO rwhp.

The wheels are great. The GT3 handles fantastic and braking is much more effortless. The wheels yield ZERO hp gains and I proved it.

The rear Dymags were 7 lbs lighter than the rear HRE 890R.

I find that a claim of 42 bhp (? 35 rwhp?) is an outrageous stretch of the imagination.

The car has about 350 kms of highway only with these wheels. I think not.

I think that's just chalk marks to determine if the tire rotates around the rim under hard acceleration and turns. How come it's got 295's instead of the GT2's stock 315's?

Yeah, the surface was concrete (dirty) and it was raining.

I have no idea why he's on 295's.

Oakley Design sell these for the Porsche market in EU, sole supplier.

In other parts of the world, like the US, it is apparently different.

That's why you hear/read about the Oakley Design wheels.

I have to agree here...........in terms of power..

We tested the wheels under race conditions and were the first Porsche team to run these in the USA.

We did find a advantage under racing conditions using the dymag wheel over a conventional aluminum wheel.

1. Tire pressures were much more consitent overall.
2. We could run a higher pressure starting out.
3. Braking could be done with less force and at a later time.
4. Tire temperatures were much more consistent under yellow flag conditions.
The tires did not fall of in terms of temperature during this period and required less work to get them back up to temperature.
This is due to the nature of the barrel which transfers heat much better than Aluminum.

We are only talking about a few hundreds of a second per lap but mutliply that over an hour or two and you have a definite advantage.

Hope that helps!
