Cayman GT4: Where are we up to now?
- Thread starter Motorhead
- Start date
I think we all know which is quickest, it's about lap times after all, last time I checked I could only flat shift at 2/10ths or a nice normal fast shift is 3/10ths not quite as quick as PDK's 0.04 seconds time 
they must feel that gain overrides the extra 44lbs weight to lug around.
Just driven the TTS DSG home which was 90 odd miles, the shifts are mega but there is just nothing to do !, yes it's great tech, but to drive after a few giggles it's not that exciting to click a micro switch how ever fast it does it.

Yes but your maths is not taking into account the bigger equation. The speed you gear change is not 100% proportional to the lap time as you already have momentum, it's the time off the power and on again which 'may' add up but it would be really minimal IMHO. And don't anyone show that American comparison video as the cars are totally different spec [MrDemon said:I think we all know which is quickest, it's about lap times after all, last time I checked I could only flat shift at 2/10ths or a nice normal fast shift is 3/10ths not quite as quick as PDK's 0.04 seconds time

the last lot all seem to have Dunlops, which is shame for the new owners :-(
ps my 2/10ths and 3/10th times is time lost over all, not shift time hence the faster time for a flat shift when looked at via time over distance chart.
what is more interesting is how little you change gear on track, take Donnington you might only change 5 times so then you have to work out if the extra 44lbs slows you down more than 5 gear changes. (it does not sadly)
Also these dual clutch systems work better on turbo cars to keep it on the boil, I would always go dual clutch on a turbo.
When you look at the touring cars the weight seems the bigger issue if you win and have to take the extra weight penalty ! but then they add 60kg (130lbs)
An extra 10kg slows down a F1 car 0.3 seconds a lap, who knows what that means on a GT4 vs gaining 3/10ths on every shift vs an extra 44lbs, the lighter weight prob only offsets 2 gear changes which leaves the PDk lapping faster over all
and of course that much faster every change, plus every change 100% perfect.
If you raced an oval manual would lap faster ;-) but on a track with more than 3 changes it looks like PDK has it.

Flan,
Hope you change your mind when it arrives, but I suppose the opportunity to make a fast buck is too tempting for you. Something you may live to regret over time because there'll always be a good used market for the cars, if not at the currently inflated prices, but I suppose there'll always be the chance to purchase a used car at a lower price in a few years time.

I've recently put Dunlop Sport Maxx on my daily driver and they are the best road tyre I have ever used in wet or dry. Grip and traction is excellent and they're quieter than many others (especially Conti sport contact 3). Therefore although the Race Maxx might lose out to Michelin cup 2 on the track, I'm sure GT4 owners who only use their car on the road will like the Dunlops a lot.
Mr D - My last car before the GTS was a Suzuka Grey TT RS Manual with Buckets, Sports exhaust, Bose etc ... What a great Car - why did you go for the hairdresser TTSMrDemon said:I think we all know which is quickest, it's about lap times after all, last time I checked I could only flat shift at 2/10ths or a nice normal fast shift is 3/10ths not quite as quick as PDK's 0.04 seconds time

scared the 5 Cylinder RS would render the GT4 Pointless LOL ... Trust me , it's true ... They are totally in another World cross country and give the V10 R8 a decent run for its money! I am sure one day i will get another one ... For £25k nothing can touch them
Specification Lock Out Tomorrow and going the Full Hog on PCCB, they are the best brakes Porsche have ever built on arguably one of the best sports cars Porsche have ever built - there seams so few getting specced with Ceramics and CS that i feel with CFB Seats, Club Sport, Ceramics, Chrono, Carbon Fibre - its a very expensive, yet very rare car ...

I had one way back in 2010 brand new with 415BHP 430lb/ft
a nice set of OZ's, PSS,upgraded IC, sus and brakes. fastest car A to B 40-60mph in 1 second faster than a 911 turbo and a gen 1 GTR.
Had my car for nearly 3 weeks now, only about 300 miles to date but have to say it's a great car on the road and as much as I'm enjoying the manual gearbox, if someone offered me the same car with PDK it wouldn't take me long to agree to change as a GT4 with PDK would be another step forward. That's my own personal view, we will all have our own.
A couple of niggles with the car and wondered if anyone else has had the same.
PCCB, they are noisy with squealing at times, and overall at slow speeds you can easily hear the pads on the disks, never had this on my 997 Turbo but awesome brakes.
Going over certain bumps, (deeper than normally accepted ) the car seams to make a hard sharp cracking sound, I can't replicate it so a bit unsure where it's coming from, except it's the rear.
The passenger seat belt keeps tapping which is just annoying.

They all do that Sir - really.. I just wrap a small piece of cloth over the buckle
Don't get me wrong, I am really enjoying the manual box, I suppose the easiest way of describing it is that with the manual I'm always in control and driving the car so I'll change my stance a bit and say I would like a paddle shift manual box, to which I don't think we will ever get.
