Good Indies such as Fearnsport will be able to do this - I believe they change the CWP, may as well fit a single mass flywheel whilst your'e in there...

AutoQuest have developed something. But they are US based. Not sure who/if they have partnered in the UK

They also offer a longer sixtg gear so that 1-5 are shorter and 6 remains the same for cruising.

Guards do a gear set.

I did not think you could do a final drive change due to wear etc.

If you have a GT4 you are better doing a part ex for the new one than modding imo. or at least waiting for the spec to be shown which will be about Feb 2019 before throwing £££ at the old one.

The gear set is just one issue the GT4 has, there are a load of annoying issues with it imo to do them all would cost a few ££££

the new car might fix or should fix 3 or 4 of them due to progress.

Newer does not always equal better,the 718 gt4 could still have long gearing, a weak spot somewhere in the engine/transmission , an engine that performs in a similar way to the 981 plus the 718 is not as good looking as a 981.
Personally for the few extra horses can't see the point in trading up from existing model unless it brings something more than a few hp extra to the table over the 981! The 981 has been around for 3 years now and the only 'potential' reliability issue is the 3rd gear.

when you look a the range of cars newer is always better until they do a big change then newer is st.

the Cayman R and 997.2 GTS were the newest in the range and were the best cars by miles

the new GT3 and GT3 RS make the 991.1 looks meh !!

when new is st is when they bring in new tech like PDK and EPS etc 997.2 and 987.2 PDK is poor, 981 and 991.1 EPS is poor.

The newer PDK and EPS is amazing.

If I owned a GT4 now I would be either selling for a 997.2 manual GTS or part exing for a new GT4.

So MrD if what you are saying you would keep your 981 spyder over the 987 spyder and your 991.2 gt3 would be PDK?
Just joshing for me Porsche ended late 2011 and they ain't getting any better and I personally don't think the .2 models are any better than the .1 models a bit like upgrades on your phones the older versions remain the most reliable

I think you would like the new manual GT3 the steering is really good to a point it’s now a non issue. I thought also 2011 was the end, ffs I bought a GT4 then 3 months later bought another R for fun. But as they get the hang of some tech like eps then things catch up.

So now that the OP was proven right that newer is not always better. And gearing remains one of the flaws of this car, has anybody in the UK tried a shorter final drive ?

After all it was what Porsche themselves did when they still had some freedom back in the day from the 997.2 to the .2 RS.

But the newer car is better in every single way bar a lack of noise.!
The 1st lap time posted has it much faster a car by a much bigger margin then people expected.

Where is the lap time D? Which track?
I reckon you need same day, same track, same conditions, same driver and same tyres to make a comparison.

The issue is same torque, same gearing, a little bit more weight. Same 0-60 and we haven’t seen much by way of over in gear times.
So wear is the performance gonna come from?

True , but with the new torque and bhp along with other minor tweaks we should expect faster times.
Time will tell as other laps will come, but it will show favour to the 4.0l car.

Looks like Understeer City, compare with old Walter’s style

But then that will never happen in an organised magazine test. No one has ever bothered even to do a test with the same tyre on the gen1/2 gt3 or rs...

Don't think you can realistically doubt the gen2 is always going to be the (slightly) better/faster car but the main performance improvement that drives the headlines is as ever going to be tyre driven.

Cup2 to cup2 N spec will be negligible if even measurable.
The times are coming from R spec cups.
