OZ Racing and TireRack are proud to Introduce the Challenge race wheel. At the request of several of our race customers, we asked OZ to design this wheel to be the difinitive cast product truly designed for track abuse. Designed in a 9 spoke design they are stiff enough to withstand the rigors thrown at them by 911 GT3-RS (non ceramic brake) , M1 and M3, GTR, and Viper owners on the track. Weight is in the 22.5-24 lb. range and they available in the below sizes. Carbon fiber center cap in 5 bolt configuration is included.

Priced in the $420-580 price point, I have inventory in stock presently, and more on the way. As some fitments are not available on our website, please contact me direct to order!

 

What about for the 997GT3RS with the ceramic brake owners? Any 18" options from TireRack?

Good looking wheel. I may give them a try on my RS 4.0L

The perils of PCCB....sorry.....

 

Hi.

You list the GT3 RS.
Do you have the 18" centerlock for the 997.2 GT3 with standard brakes(2010)(non-RS, non-PCCB)?

Thanks.

Stop waiting and use 235. Works just fine.

 

Yellow PCCB and Red GT3 calipers/rotors are the same size....these wheels should kit PCCB cars too.

 

The Challenge wheels clear all 380mm rotors and calipers just fine.

 

Great news! OZ has just added an 18 x 12 ET63 fitment for GT3. They are on the way!

 

Guys,
i am very confused here, is the PCCB having 380mm rotor? If the wheel will clear the 380mm rotor, dose it mean will fit the 997.1GT3RS with PCCB. Please advise guys?????? Is the red and yellow caliper the same size?

 

All the center lock equipped GT3,GT2,GT3RS, GT2RS use the same dimensions for front and rear brakes, and the same calipers. Front rotors at 380mm diameter with 6-piston Brembo calipers, and rear at 350mm diameter with 4-piston calipers.

If these wheels will clear the brakes on the 2010-2011 997.2 GT3 with steel brakes , they will work on the PCCB as well.

The first generation 997 GT3, came with different dimensions for steel brakes and PCCB, but these cars don't even use Center Locks, they use 5 lugs. The original confusion was the pre-centerlock brakes.

If your car has centerlocks, the wheels fit the car fine.

Sorry for the confusion.

 

will 5 lugs version be available any time soon? looking to pick up another set of track wheels this season

 

I have been looking for the 5 lugs version that will clear the 380mm PCCB, wish OZ consider there is also a market for the 1st gen.

 

Yes 5 lug? with aggressive offsets?

 

You can get these wheels and have BF goodrich R1 (like a Hoosier R6) mounted and be in the $3300 range all set ready to go! WOW!
