James, I asked Loren and he confirmed they are 9's and 11's. It does sound a little strange as I know the front wings are 20mm wider than stock...
What size wheels are on that incredible 996 RSR? They looked identical to the 997 RSR wheels, which are one piece, right?

Regarding tires, I did 2 back to back tests at Willow 2 weeks ago and found the WC spec Pirelli .5 seconds faster than the new 25/65/18 and 30/68/18 Michelins.....trust me, I was surprised too! This substantiated our findings at Rennsport when we were .5 seconds slower than the Pirellis run there a month ago under the same conditions.
The Pirelli compound felt a little softer as the Michelin was so much harder after one heat cycle. Then the fronts went away on the Michelin and that killed the performance of the tire.
The Pirelli size is 275/645/18 and 315/675/18.

John,
Your Cup is a narrow body, correct? I have the fronts but have to check on the rear fitment as I am not sure I have the narrow body, only the wide RS body fitment......I also have the BBS E88 fitment for the narrow body to make an 18x12 rear, which is what we ran in WC from 2007-2009.
You can buy the Pirelli Slicks directly from us as we are a Pirelli dealer for both slicks and the new Trofeo tire.

Here are the ones I like. They are pretty close to the 997 RSR look. I have never been a fan of the "convex" E88 centers. I know they are super light, but just can't get used to that look. I added another picture of my car so you can see the rear quarter and how the 11" wheel fills it out. I suspect I would have to change to the wider RS quarters to make the 12's work. If that's the case, I will wait till it's bodywork time and make the upgrade.

I great buy available right now in the traditional 240/280 cup series tires is the 2010 Yokohama IMSA Cup/Patron series tires from last year. Trackside Performance, the US distributor for their race tires, is located in Orange County and has them on sale at $1,800. per set down from $2,250. last year. That's probably the best deal available right now....

John with your WHP you should most definitely consider widening up the rear especially since you already have the wider front fenders. The you won't need to compromise on rims, get the 13's back there and run the bigger tires....

Can they be widened, or is it easier to just buy the wider RS quarters and bumper cover? Either way I think it is something I will do if and when I need to do some body work. I sure do love those 997 RSR wheels though...I could almost create a "poor man's RSR" lol

Fitting 13" wheels isn't the problem, it's the tires you put on the wheels that will be the issue.
RS quarters are the way to go but to fit the 13" wheel in the back with the 31/71/18 tire, you will need to tub the rear quarters quite a bit......we did this with our GT2 Cup and 2008 WC Cup cars. This will enable you to lower the car to the proper ride height as well.
The Monoblocs list for $2495 front and $2795 rear......crazy expensive but I can work out a group buy with our annual buy for the WC season.
Stay tuned....
