Plus, as you said, it's optimized to the computer systems, of which there appears to be a lot of them on the C7.

Also, not sure how the brake cooling is set-up on the C7, but there will probably be a little room for improvement there too and it'll be cheap.
Haven't seen a C7 but suspect you are correct.

This works on a C6 Z06:

2 piece Colman rotors with alum. hat/ race pads... hi temp brake fluid... modified street/track alignment and corner balancing...

Harness bar and belts.

You should be good to go!!!

From what I saw the C7's brake cooling consists of nothing more than the C5 and C6 had, the ducts just dump air into the fender well and not routed to the rotors. I'm sure DRM and others will have their spindle ducts kits ready when the C7 hits the market.

One of the reviews shows (primitive) scoop ducts under the floor line that were described as funneling directly to the rotors, others were presumably directly from the front of the car ducted to the back of the rotor/caliper.

As with the GT3, it should be simple to screen these ducts and add an inch of extra lip here and there or replace the underbody intakes with NACA ducts.

Given the C7 is an entirely new alloy chassis, presumably the after-market folks will need time to get their hands on and go through a few revisions to figure out what they can actually improve.

It seems to me the reviews were good enough to suggest that you could track the Stingray "off the showroom floor" with little more than a quick shakedown drive, a nut-and-bolt inspection and then go through a few sets of tires and pads until things made themselves evident as weaknesses.

You're right. They should be good to go off the floor.

Even without functional ducts to the rotors, these cars, beginning with the C5 have been very trackable cars brake wise. For anything over ~30 minutes the ducts then become more beneficial, and I'd expect the C7 to be not different, but even better.

No doubt the scoops get the journey of cooling air started, but unless there are ducts positioned right into the center of rotor, the air going into the fender well doesn't do much.

I'll talk to Pfadt and see what their plan is for the car. They had a nice bolt in hoop/harness bar for the c5, one for the C7 would be a great idea. I'm sure they will have a coilover and a magnetic ride coilover for it and their new tri-Y headers that they have engineered and now are building in house are works of art. I'm sure they could do the same for a bolt-in roll bar.

It would be nice if someone would develop a decent hoop for the C7. No one really has a decent one for a C6 Z06 because of the aluminum frame. Hopefully, someone will find a practical solution.

Ducking the air to the rotors is not a big deal. Flex high temp plastic tubing (local Napa store) and wire works well. Same issue with "skip shift" expect we will be able to bypass that too.

Now towing a small tire trailer with the C6 Z06 turned into a challenge, working out the trailer hitch!!! Maybe the hitch will work with a C7...
probably NOT.

All at MSRP.
Thanks. I did some searching around and found one reference to a local dealer not gouging, so I shot them an email, just to see if they can deliver cars in a realistic time frame. I don't mind playing with the Stingray and have it as a comparison point for the 991 GT3. I'm told it will be "2014 Q1" before Mr Porsche deems it appropriate to build a car for me. This will be a "second in line" build slot ... one car per quarter per dealer? Surely they'll quicken the pace over time.

The C7 z51 with sport seats and data and video recorder option seem to be late delivery.
Q1 2014. Ill wait for that..

Just got my first on track C6Z experience today. Driving 7/10ths on PS2's and took the GT3's on hoosier slicks everything they had to pass me. I would have turned up the wick and got them, but was coaching a buddy and didn't want him to try what I would have done to catch them. Potent cars indeed.

A shame the motors cannot be trusted. If the C7 improves on that, and builds a reliable motor this time Porsche's in big trouble IMO.

How did it feel in your hand and to your behind?
Stock or setup right?

I how the C7 has a bit tighter, refined feel. Initial drives seem to confirm its OK.

Nothing a set of WCCH heads and stainless valves wouldn't cure and for about $3500 installed. And, you will pick up about another 50hp as well.

TRAKCAR,

Did you ever read Mikymu's write on his Z06 conversion? He is turning similar lap times in his Z06 as his Cup car.

Z06 is definitely not as refined nor as well made as a Porsche but for pure speed and bang for the $$$ they are pretty tough to fault.

Can't see how Porsche 'will be in trouble' most GT3/RS owners don't track their cars and most of those that do track are more interested in improving their own skills and bare no interest in what others are doing with lap times. Porsche will sell more of the 991 GT3's and RS's because they have made they more accessible through technology and mainly because of the increased build numbers purposed.

I agree there are some that will hurt if the C7 is much faster in the right hands than a GT3 but out of these only a very few will not purchase for this reason, numbers in the 10's not hundreds.

The large majority of Porsche buyers buy because of the passion for the brand and aspirational reasons. For me it was seeing a brand new red 930 turbo when I was 4, from that point I was hooked on the shape/styling as it was so different from everything else out there and to me the 911 had beautiful lines. My study of the brand gave me more depth to the desire, this included technology, company ethos and racing pedigree of the BRAND not necessarily the model.

I could have faster and superior dynamic cars but I chose to scratch the 40+ year itch.

I don't aspire to the C7 nor do I fancy the styling. I am not racing for a career or for prize money means the fact there are faster cars out there does not influence me and I would suggest the majority of other Porsche followers.

Just my opinion which I am happy to stand behind with my cash.

Jay
