Im looking for the part numbers for the 997 Gt3 front Calipers for 380 mm brake discs and part number for 380 mm brake discs.
Same for the Back, Calipers for 350 mm brake discs and for the 350 mm brake discs. Cant find anything in the web or with the Search.
Im looking for the 5 lug locking not for Center lock.
Thanks

 

All that is in PET. Call any dealer and they can look it up for you. I can look it up later if you need. The parts are different for the 380/350 steel or PCCB.

 

Normally I wanted to install the 997 GT3 PCCB calipers with some 2 Piece aftermarket Rotors, like your Setup, but I stopped this and now I want to go for 997 GT3 Calipers for 380 mm Steel Rotors in the front and 997 GT3 Calipers for 350 mm Steel Rotors in the Back.
I only found the 380 mm Steel Cup Version in 380 mm, but not the normal.
It would be very when you were able to take a look for me for the matching calipers and Rotors.

The only 380 rotors you can use are going to be aftermarket unless you go with the oem 997tt 380 ceramic rotors. All front GT3 rotors are the wrong offset and can not be used on the TT. The rear 350 rotors are easy since they are the same offset on the TT cars as well as GT cars. Many choices. Calipers are easy, any front 997GT2/3 PCCB (yellow) or Cup (red) or 997TT PCCB (yellow) calipers will work. The TT calipers have larger pistons than the GT or cup calipers, that's the only difference. The rear calipers are all the same, either red or yellow. Note, the first generation 996 GT3 6 piston front calipers will bolt up to the TT hubs but will NOT work with the 380 rotors, only 350 rotors. They will NOT space out radially due to their design to accommodate the 380 rotors. Hope that helps.

 

That helped me alot in my decision, thank you John!
So this choice is gone and I will go with the 997.2 PCCB Calipers and the more pricey Aftermarket Rotors, maybe it will be the better choice to go.

 

You are welcome Bastian. Below are the part numbers. I would recommend going with 997GT3 PCCB calipers as opposed to the 997TT PCCB calipers. The GT3 versions have smaller pistons (about 20% less piston area) and will further shift the balance to the back while giving you an even firmer pedal. I have run both and much prefer the GT3 versions. This brake set up along with the larger 997 GT3 master cylinder is phenomenal, much much better than the old 996 GT3 versions. I have 11 track days on this set up so far and absolutely love it. The car stops much quicker and more composed due to the fact that the rear brakes are now being utilized to a much larger degree than with the stock set up. Cheers...

Front 997GT3 PCCB caliper part #:
997.351.431.92
997.351.432.92

Rear 997GT3 PCCB caliper part #:
997.352.425.98
997.352.426.98

 

That sounds perfect, I cant wait to collect all the parts and get them into my car , thank you so much for your help.

Cheers

 

Good luck with the project Bastian. Feel free to contact me with any questions. Oh, and don't forget you'll need the Porsche Brembo adapters on the front. Here are the pics of the rotors I'm using.

 

Thank you John, I appreciate that! I already started to collect some parts, but the most expensive parts are still in the To Do List and will come in the next time. I was also happy with my old brake Setup, Original 996TT calipers in the front and back with some Adapters and 350 mm Rotors front and back, brake pads are Cool Carbon. But we have n1 Highways here in Germany where I can drive with high Speeds and I have to brake often for slower cars which are crossing my line. With the 350 mm Rotors and OEM 996TT Calipers Setup it is always a Problem for me after 1 big brake from higher Speeds that the Brakes are too hot and Feeling very bad.
I hope with the new Setup it will be much better, I think it will be big improvement over my current Setup since I make a very big step Forward with the new System.

Here are all the parts which I already have purchased:

- 2 Adapters for the Front, 997.351.505.02
- 4 Bolts for the Adapter Fixing in the front, 999.073.313.09
- 4 Bolts for the Caliper Fixing in the front, 999.067.054.09
- 2 brake steel lines for the front Calipers, 996.355.587.03
and 997.355.588.03(Instead of bending/ modify the old ones)
- 1 brake master cylinder, 27 mm shaft, 997.355.910.30(I bought it directly from TRW, the manufacturer, same part but much cheaper, part No. TRW PMN 166.161)
- 2 996 GT3 Cup brake ducts for the front(Instead of the old smaller TT ones), 996.341.117.90 and 996.341.118.90
- 2 996 GT2 brake ducts for the rear(Instead of nothing... ), 996.331.127.90 and 996.331.128.90
- 1 custom brake line for instaling the new brake master cylinder(Thank you John )

Thats all at the Moment, lots of parts....
I want to go with some Special compound Ceramic Replacement Rotors(HTCIC - High-Tech-Cast-Iron-Carbon) with 380 mm in the front 350 mm in the back. Also I will powdercoat my Calipers in RS- Orange


For the new Calipers in the rear I Need some new bolts to fix These or I can use the old ones from my Setup from the front or back?

I like your Setup!!

 

Somebody can tell me how much it will cost to get them fully rebuild?
Powdercoat is not a big deal and already calculated

zeckhausen racing has rebuild kits at 42$ per caliper. fwiw i found a complete set front and rear for 1300 for a friend. those are priced way high

 

Those calipers are very clean. I would just use some goo off to clean them up and a little touch up paint. No need to do anything else. There is no heat discoloration. The inner seals are likely good and you can get the dust seals are not included but can be bought directly form the dealer. The part number is in PET, 28/30/32mm are the sizes. For a complete rebuild, Porsche Motorsport sells a factory rebuild kit that includes the pistons, zircon inserts, and seals. 997.351.959.91 is the part number. Dust seals are not included but can be bought directly form the dealer as mentioned above. You need two kits to do a pair of calipers. I would also get the zircon puck retainers from Porsche Motorsport which keep the pucks from falling out. They are very fragile and crack easily. They can not be bought separately.

I assume you already have the 997 rear calipers Bastian? You can not use the 996 versions with these fronts, but you probably already know that.

 

Are those the 997.2 380 calipers Steve? That's a good price.

 

thye were a set of 350/350 john 6/4 setup

 

Gotcha. That's about the right price then. The ones in the eBay ad Bastian is looking at are the 997.2 380s. That's a decent price for those actually as they are a lot harder to come by than the 350s.
