Default GT3 rear wing vs touring package/Gurney flap

Sorry if this question is already out there. I didn't see it.
Is there any information out on the physics/track times for the standard GT3 wing vs the Carrera style wing with Gurney flap offered on the GT3 touring package? All the posts I have seen comment on the obvious aesthetic differences.
Please advise. Not sure which to order. Appearance much less important to me than performance.

Thanks!

I’m assuming you are going for a manual transmission and thus looking to compare manual GT3 against manual GT3 Touring? I’ve seen a lot of conflicting information to this question and no concrete or official answer. I think GT3 Touring has a 1 mph greater top speed not that will make any difference. GT3 with wing more downforce for corners but more drag? Question would also be straight line performance vs cornering and therefore the layout of the track and number or corners and angle of corners would be a factor.

I can’t wait to see some more reviews and road tests come online to cover the manual cars and make comparisons between the current and previous models.

It's a GT3, it should have a wing.

A manual GT3 v manual Touring, all else equal (brakes, tires, driver, track conditions) is likely going to be too close to call except under the most precise testing and on longer tracks. I’d bet the difference would be within the margin of error or variability of lap to lap times from the same driver in the same car.

But PDK would make a much bigger difference.

This is is all academic. Who really buys a Touring pack car, much less any car with manual instead of PDK transmission, car with lap times in mind anyway? It’s aboit the fun of the driving experience not beating others with different cars. Or if going for lap times, it’s about beating yourself and improving your own driving skills, not speculating about how a wing could make you faster.

Having been driven some some hot laps by a pro driver in my own .1 GT3 it’s obvious these cars have much higher limits than vast majority of us are able to exploit. It’s about the driver not the tech specs of the car.

The ONLY concern here is looks. And there's nothing wrong with that. But you will NEVER unlock the 10/10 performance Delta between the two MT versions. Ever. Not even close. Don't even worry about it.

As others have said I highly doubt most of us here on RL have the skills and cajones to unlock the performance of the car where the wing vs. touring pack rear could be noticeable

For me it came down to looks and I just couldn't shake the notion that a GT3 should have the wing, it just completes and "makes" the car for me

It becomes a transmission choice as well if you need/want PDK like I did

Your profile doesn't say where you live. If you live in Germany or expect to drive there (including Euro Delivery), then you may benefit from the extra downforce of the fixed wing on Autobahn and Nordschleife. Otherwise, unlikely to matter in most other conditions.

I think you have to come pretty close to Vmax to benefit noticeably from the fixed wing (over 160mph/260kph perhaps), since the Touring Wing and diffuser do produce some downforce.

Where is the link to saying the wing has more downforce than the flap?

Looking at the trap times for the various speeds, the touring (flap up) has more drag than the wing. IIRC the touring is 1 mph slower vmax, not faster. Drag is obviously not the same as downforce, but so far I have seen nothing that compares the downforce between the two.

Just got back from LAAuto show. Glad I made a decision to spec with wing. The silver gt3 touring looks like a base carerra. Lost some of the GT3 look. Less muscular. Even the Carrera T with buckets looks more special.

There was some chatter indicating that the Touring was a bit unstable at high speeds and hence the gurney flap...I would go for the full GT3 wing, as opposed to what appears to be a slight afterthought, especially if performance is your goal.

You have to add 20psi to the winged car's tires. So much downforce it makes.

I was also a the LA Auto show yesterday and was also very disappointed with the look of the Silver GT 3 TOURING there. It did indeed appear to look like a base Carrera, in fact that is what thought it was till I walked to the back of the car , it will be interesting to see how it looks on the street.

It will still look like a base Carrera. I mean, that's the whole point to the Touring. isn't it? To take away the racer look of the wing, so it will look like a base Carrera but have the GT3 mechanics.

EVO magazine mentioned the touring package has a shorter front splitter to balance the decreased rear downforce from losing a wing, so it sounds like the touring makes less downforce front and back. That's the only place I saw a mention of that.

For some, me included, looking like a base Carrera is perfect. I don't track anymore but when I did, I also loved driving the GT3 on the street although was always a bit uneasy parking at work, made me a gossip topic. I am looking forward to driving a 911 that feels, handles, performs and sounds like a GT3 (it is) while looking like a base Carrera to most.
