Looks good. They even include the steering rack stops and the tire pressure monitors in the package. He said it felt like a real race car during testing at Hockenheim. With same OD's and full clearance on the calipers, no other mods are required. Sounds like a project for next spring.

When I look at the Manthey-Motors page, it shows 27/65-18 with S7A (soft) compound on the front and 31/71-18 with S9C (hard) compound for the rear.
When I replaced my CGT tires due to wear, the fronts were the ones that showed the most track wear, not the rears. I don't quite "get" why Manthey selected the heat ranges for their slicks package as soft in the front and hard in the rear. Maybe my stock tires wore out in the front, but ran hotter in the rear?

I was at Manthey Racing yesterday and the price of the wheels complete with slicks is around 10k euros - 16% German tax if you can reclaim this.
The option I will probably go for are the BBS Magnesium split rims in 19" front and rear, then fit the Pirelli P zero corsa. I was at the Nurburgring with a 993GT2 and Manthey GT3 for the last couple of days and these tyres really are the closest to a sticky MPSC/full blown track corsa that you can get.
Combined with suitability for the wet and the price of around £4k GBP including tyres makes a good option for the track.
Manthey are developing a hydraulic lift kit, upgraded KW suspension kit and some carbon aerodynamic modifications which will be on the market in the summer of next year.

I don't know why there are no PSC's or corsa's, even my 996 GT2 which never had corsa tires originally has them available and they are N rated. I think there were less 996 GT2 made vs. the CGTas well.

redpackage, I have no details of the 19" tyre size for the rear when using the BBS magnesium rims. There is a picture of a white Carrera GT with this configuration on the web. I think the car is from Europe and was photographed at Hockenheim with these wheels/tyres.

RS Clubsport,
Do you refer to these pictures?
(Thanks to the member of the Club 911.net who showed them to me.)

That's the ones! Shows the 345/35 19 rear size, but on tire rack there is no listing for the fronts which OE size are 265/35 19.
I'd be interested to know what the Corsa front tyre is. I know what rim sizes they are as BBS Motorsport have advised me.
This will be a good way of increasing grip on track and preserving the original wheels.

I uploaded the original picture #3 which shows the left side of the car. Using a simple zoom function I could read the FRONT tire markings of XXX/40 ZR 19. If someone has an image processing algorithm I'm sure they could read the full FRONT tire size right off the picture. The REAR tire size is clearly marked 345/35 ZR 19.

After reviewing the Pirelli web site and the enlarged picture one more time the best guess for the FRONT tire size is 255/40 ZR 19 with the REAR size at 345/35 ZR 19.
Thsnks to washington951 for the NSA like effort.

Spoken to Pirelli, in the Corsa the best tyre sizes to match the rolling radius on the Carrera GT are:
285/35 19 front
345/35 19 rear
This keeps within the 3% deviation from stock you are allowed.
I've e-mailed BBS motorsport to see if they can confirm the client they supplied a set of these wheels to (the white car in the pictures) has these tyre sizes.
This will be an excellent option and with the 20mm wider front it should help to quell some of the inherent understeer people comment on. This equates to £3700 GBP wheels and tyres!
