O.Z. Wheels for R8

[MichaelP]

..... the OZ wheels at TireRack are only a few hundred dollars more for a full set, they are forged (the factory wheels are cast), and they weigh considerably less. .....".)

HMP10, where do you get your information that the factory OEM wheels are cast? The parts counter at least one of the the local dealers here in Colorado, McDonald Audi, has "opined" they're (in the 19" size at least) are forged.

Then again I don't think they really have any real authority for their view, other than opinion, and the assumption Audi wouldn't be cutting corners on a high performance HALO product.

Don't know what you may have found out that is more authoritative regarding cast vs forged, but the AudiUSA website calls the stock wheels a cast wheel, here:

Was hoping those of you seriously tracking the car can give us an update on which wheels and sizes you selected for your track tires?

I bought a set of O.Z.'s as my flashy street wheels, and used the stock wheels for track tires. I got the optional 19" titanium wheels on the car when I bought it.

I use Hoosier R6's, which are relatively expensive track tires but are way sticky. Hoosier does not offer the 305 width in the 19" sizes, so I had to go with 295's on the rear instead of the 305's, which are what came on the stock wheels. The sizes of the front tires are the same.

If I had gotten the 18" wheels on the car originally, there are more size options available in track tires than with 19". But 295's in Hoosier R6's are plenty good for occasional track days.

Hoosier 315 rear fits fine / flush on OEM rim.

Hey, great to know. Think I'll try that next time.
