Porsche should offer lower intermediate ratios 'for track use' as an option. Then they could quote acceleration figures for the standard box to keep 911 owners happy and make GT4 owners happy with the option.
I wonder how long it will be before we get adjustable ratios?Its certainly possible. Everybody happy!

Don't believe everything you read 
There has long been a wide variety of gear sets available for the boxes in the GT3 cars available from Porsche Motorsport alongside alternative products made by very good race suppliers.
These have never been available as an "option" to my knowledge despite anything Autocar may have said (I looked but couldn't find it). The gear options are a supply from the race programs.
The basic box was shared in the road car and the race car until the sequential took over meaning a road car owner "could" have a shop regear their gearbox using the race car parts if they wanted. The same applied with the 4.00 final drive which was also from the race cars. Many owners carried out the latter, fewer did the former.
One issue with the regear was that 1st and 2nd gear are fixed to the shaft in the street box. To change 2nd gear, one is required to buy the race car shaft. This costs about the same as the rest of the gears put together.
On the GT4, as I have posted already, there isn't a reliable final drive option available.
One exists physically but it is (according to my info) unreliable, needing replacement every weekend give or take. I haven't used this part myself so that info is what it is though was given on good authority.
The one option that would have typically been a go to for a reliable part in this area is, as last I heard, not going to develop one for several reasons.
There are already a range of fully developed gear sets available that can be used in the GT4 to regear the box to whatever you like. These gears have been race tested (including daytona 24hr) and have proven to be solid, effective and reliable. Even if a decent final drive was available this would still be the way to go. The GT4 gear ratios see it needing shifted below redline in all gears from 3rd onwards. Holding to red line loses acceleration to the next gear.
It is worth mentioning however that any option such as this brings with it a risk to those new car warranties. I imagine that will suffice to put most off from doing much but talk about it and all the permutations they could have.

Surely all the Porsche Motorsport (or equivalent) gear kits available are straight cut or dog gears, and not synchromesh gearkits..? In any event, changing any part of the transmission system is going to invalidate the warranty on the GT4, so is likely to be a non starter for almost every ownerThere has long been a wide variety of gear sets available for the boxes in the GT3 cars available from Porsche Motorsport alongside alternative products made by very good race suppliers.

They weren't dog gears until the sequential box was introduced with the 996 RSR/997 Cup. Before that point the 996 R/RS/Cup all used synchro gears.
As such there is a wide range of gear sets available that can be used in the street boxes in the GT3 cars.
Back on topic though. GT Gears have a range of gears available that will work in the GT4 that they developed for/with BGB for their racing Cayman. Like all their products, the quality is incredibly high. They will also have a diff available to replace the zero preload thing installed from the factory.
Gears always seem to be a funny one. Very few people seem to be actually interested in having them done despite the same conversations regarding gearing coming up on some Porsche model or other in pretty regular fashion on the forum. Ignoring those under warranty who have hands tied of course.

I think that after driving a car for a while you can get a pretty good idea of what changes you'd like to make to the ratios. If you could lower 2nd and 3rd, re-space 4th and 5th to suit, and leave 6th unchanged, which I think would be the ideal, I doubt the next buyer would realise you'd done anything unless he was quite familiar with the GT4, in which case he'd think what a great idea and want yours over all others. It's just the warranty and cost.
Yup, makes total sense and pretty much my view on the gearing. Contrary to claims that there's no scope for tweaking it, I think there's plenty and roughly as you put it. But I know I'd still prefer to try it first before unloading a hill of cash.
The other thing is that if one was really into full on modding and the absolute last word in fine tuning the car to your preference - or rather if that was the intention, I suspect an older GT3 of some kind would have been the choice, anyway.

So out of interest have you had a full test drive of the gt4 ?
Hello Mcfly ? 
Had my GT4 PEC day on Friday.
The only other sports car I've ever driven is my Cayman S (I'm not counting my old diesel Scirocco or 330Ci as sports cars) and the GT4 is a whole new thing. The S is dead to me now.
Loved the noise, loved the power, loved pretty much everything. I do see why everybody's been banging on about the long gearing now though. My S is PDK so you can pretty much let it do its own thing without a second thought. I'd like more opportunity to use the box, the shift is lovely and I think the noise would be better with more rapidly rising revs. It's also annoying that Motor Trend keep saying it would do 0 - 60mph in 3.5 seconds if it was geared to do 65mph in second like most cars are.
I didn't think the clutch was overly heavy (but didn't need to use it much because of the gearing), might be different in London traffic. My partner that hasn't driven a manual for 7 years had no problem with it, he was very nervous but he also loved it.
I drove the black car which had 18 way seats, the same as I have in the S, I would have preferred to have a go in buckets since that's what I've ordered. It's noticeably lower than my S on standard suspension to get in and out of.
PCCB's were awesome on the new part of the track where I jumped on them repeatedly with no loss of performance, the pedal stayed firm.
The guy said both bars were on the middle setting and it was slightly understeery, nothing drastic but adding throttle didn't really help balance it, just more push. This was only on the handling circuit so at fairly low speeds. It is remarkably confidence inspiring, I don't think I've ever taken a car up to and beyond its limits so easily and so often before, really, really playful.
I've been keeping an eye out for a Voodoo Blue Porsche but have yet to see one in the flesh. None at Classics at the Castle a month ago and none at Silverstone. They had a Mexico C4S but the guy I asked at Silverstone said he'd never seen Voodoo. I hope it looks OK since its cost me a couple of grand and a 9 week delay.
I was totally buzzing when I got out of the car so thats a win as far as I'm concerned. January can't come soon enough.
Some photo's of the morning here.

My buckets caused a 10 week delay and PTS another 9 week delay. Why these both couldn't run concurrently rather than one after the other is a mystery. 19 week delay for spec choices was a bitter pill to swallow but I'm pretty sure I'm going to be happy as a pig in s
t when it finally arrives.

No reason given but PTS believed to be the main reason, even though I ordered the car nearly a year ago and gave my final spec about 4 months ago.
Strange I am PTS, CS, LWB and was a mid November build. When I spoke to OPC on Friday its on the system as the middle of Jan (Was Nov)Gassing Station | Porsche General | Top of Page | What's New | My Stuff
