Given recent discussions in Stout's gear ratio thread I decided to bump this. Please don't vote if you voted previously, but we have more members now than we did and I'm curious if people's desires have changed...

I had voted originally. Now, a year plus later after having driven both the GT4 and Spyder, I still think that for street driving, being able to redline and shift a couple of times before getting to gotojail speeds basically makes the car twice as fun 
that just being able to do one redline shift.

In the mean time, my vote is for 2nd to top out around 70 mph.

65-70 mph for top of 2nd gear seems like the sweet spot to me.
There's an interesting thread on another (competing) Porsche forum among 991-1S owners complaining about the MT's third gear tweak vs. PDK, called "Disappointed in 7mt gear ratios". Like them, I cannot figure out why Porsche tweaked 3rd unless it was to give PDK a clearer performance edge for marketing reasons? One poster over there figures the ratio change moves the 2-3 shift drop to 7800-5800 rpm vs 7800-6100 rpm with PDK. More food for thought.
But if custom gears are needed, Matt's approach of working from second gear outward is the right way to optimize performance in gears 1-5. And 65-70 seems like the sweet spot.

Fwiw, 65 mph might be worthwhile, as anyone doing an objective 0-60 test should log an advantage with that as a new 2nd—where the stock 2nd is too long and one a new 2nd that tops at 60 mph exactly might bring a dreaded second upshift before 60. Even since seeing the GT4's 0-60 numbers come back so lackluster vs the Carrera S, I've wondered how much the GT4's gearing hobbled it in that test, and particularly 2nd.
For the record, I think it's a stupid test—and yet I too use it as a benchmark, along with similarly useless top speed figures. Neither have much relevance for the way I use my cars, but I guess there is just that part of us that likes to know what something can do. And I do suspect there will be some magazines that could be talked into proper instrumented testing on a GT4 with truly optimized gears.

I have never made a 0-60 run and timed it, in any car, yet I have logged thousands of laps on the race track and timed most of them. I have run a 1/8th and 1/4 mile a few times and timed them. Top speed have tried to hit it in every car I owned at one point or another.
Yet I can quote 0-60 times and 1/4 mile times on so many cars it makes my wife's head spin - so somewhere along the line the car mfg. made them stick and we all look at them and measure performance based upon the data and log these useless fact in our brains. Yet in the real world they are only useful for bench racing!
Only standing start on the road that I remember was one time in my Panamera Turbo with some mods. I was at the border checkpoint in Camp Pendelton on I-5 and was stopped while they opened up the traffic - so you get about 2-3 miles of open freeway. Being the first guy in line it (in my lane) it seemed like a good idea to engage launch control and let her rip. I did all the way up to !*) mph - I was so impressed at what happened from 60 - !%) it is something I will not soon forget - not to mention watching the other three lanes of traffic simply disappear in my rear view mirror!
Ok sorry - back on topic.
I like 65-70 for 2nd for the track, but what we have works ok and with 3,4 & 5 changes available you can get a pretty nice set up.
