I see you are running the rear 350mm dimpled PFC rotors. Were you able to retain your parking brake? I was told with PFC you loose it as the hats are not set up for it.

We did not lose anything including the emergency brake system. Te changeover form the PCCB was direct and frankly the 01 compound stops us like the hand of god.
Highly recommend the conversion.

The reason I asked is that I was told the rear PFC hats don't accept a parking brake. I guess that's only the case for the slotted PFC track rotors and not the PFC dimpled street rotors.

I'll check with my engineer on the slotted ones but I agree the stopping power is amazing, give you so much room to drive deep into the zone. Looking over your mods it looks like a great car.

To answer you question purely based on my experience and what I have been told by engine builders is that the deep core components of the GT2 did not get the same quality of parts as the GT3 based on a belief by the accountants that the GT2 would not be raced or subjected to the high stresses that the GT3 would.
Now of course all this was a mystery to me when I bought the car in fact logic says it cost more new so it must have better internals. The platform was similar so I did not look further.
What we discovered is the very heart of our motors the crank is not nearly as robust or even balanced as well as the GT3, in fact the crank appears to be cast. There are insufficient oil ports on the journals creating some issues, the rods are not as robust. Etc.
Now all this said I would never go back, there is nothing that compares to the heart pumping acceleration the GT2 has and we will rise again with the new motor, however it is a shame that Porsche allowed the Accounting department to override the engineering department on this flagship car that deserves to have the best of everything.

On the contrary, boost a stock 996 gt3 engine and what will the outcome be? Just some food for thought.
Always two ways to look at anything, oh well.

I'm sorry you've has issues with your motor but I think you just drew the short straw. I drive the hell out of my boosted RUF Rturbo motor and haven't had any issues (knock on wood) besides a failed valve lifter last year. There are plenty of guys out there producing some crazy numbers with their set ups without any issues. What I'd love to be able to do when it comes time to rebuild is to have a reliable 600hp motor that would rev to 8k like the GT3s (my Rturbo motor has a 7200 redline) If anyone has any input, bring it on!

I'm glad you have had good success with your motor and the car setup does appear aggressive which I love. I hope that I did draw the short straw, but I would imagine that many of these great builds have swapped out some of the internal parts and worked on oiling issues. Of course that's just a guess as I have no direct knowledge. We will be doing a fairly powerful build on the next motor with some great torque and HP goals as well as bulletproof reliability.
Post a few photos of your car if you get the chance, always love the shots.

Here is a video of the car in the early stages of suspension set up. This is Chris Cervelli chasing down a couple of 997 Grand Am Cups at HPR on 08/02/13. Not all that bad for a street legal car driven to the track on NT01s. With the new alignment, sway changes, and shock adjustment the car feels much better. I've since swapped over to the GT3 sways and will be tracking this weekend to further dial it in. Front uprights are going to be swapped over to GT3 Cup uprights which will work much better at my ride height.. I'm pretty happy where we're at with it so far...

Have you looked at the RSS lower control arms for that beast. Also which drop links are you running.

I am running the split adjustable GT3 LCAs with Tarett solid adjustable thrust bushings and monoball ends. In the front I have Tarett extended drop links and also Tarett links in the rear.
I enjoyed your pics from COTA. A group of us would like to come and run down there next year. Looks like a gorgeous facility.

We had the shorter version of the tarret drop links originally but after seeing the difference on my SPB I have changed them out to the extended version on the GT2.
COTA is nice very nice in fact. It's a beautiful track however I actually like TWS better for driving. Once the next race date is set at COTA I will book the TWS track which is about an hour and a half away for the day before so those hauling from Other states can have two tracks to run. In fact if the dates work out we might be able to do a trifecta with MSR in Dallas then TWS at College Station and finally COTA at Austin.

I like where you have the remote canisters mounted, both front and rear. Do you by any chance have some pictures of where exactly they routed the remote canister lines through the body in the wheel wells? I am assuming they drilled a 1" hole and used a grommet in routing the lines into the cabin.
Do you know what brackets those are that mount the rear canister to the Teq. bar?

Can you two help me a little on suspension:
6gt2 with JRZ RS pro, 2.5frt/2.0r with 8 degree caster, with Cup/monoball suspension, 275/335 on CCWs driven through Motorsport diff. Currently TPC sway bars are set soft, but might want to increase them in accordance to other changes. Current aero is 4" splitter @2" off ground and large Getty wing.
What I am unhappy with is the spring rate/setup. The previous owner for some reason (maybe to make better on street) reduced spring rates to 400/600 with unknown but very soft secondary springs. I know the car was initially ran with 600/800's. Can you two give me subjective feedback on your spring changes and what you did or did not like? Currently the car is too soft for my style as I'm used to stiff TB's and lighter cars.
I totally am in agreement with the inferior internal components. Our rods have the same short comings of the 993's. Not as if we didn't know these had problems 15 years ago. I'm replacing the more robust rods on my 3.3 and my GT2 is putting down 550 rwhp on these questionable rods!
