Default 996 GT3 vs 997 GT3 transmission gears

996 GT3
R&P: 3.44:1
Stock Michelin Pilot Sport 2 295/30R18 (25.0" tall). 5th and 6th gear redline at 8,000rpm

Gear Ratio -------- Max Seed -------- RPM on upshift
=======================================
1st: 3.82 -------- 46 mph
2nd: 2.15 -------- 82 mph -------- 4600 rpm
3rd: 1.56 -------- 114 mph -------- 5900 rpm
4th: 1.21 -------- 147 mph -------- 6400 rpm
5th: 1.00 -------- 173 mph -------- 6800 rpm
6th: 0.85 -------- 203 mph -------- 6800 rpm

997 GT3
R&P: 3.44:1
Stock Michelin Pilot Sport 2 305/30R19 (26.3" tall). 5th and 6th gear redline at 8,000rpm

Gear Ratio -------- Max Seed -------- RPM on upshift
=======================================
1st: 3.82 -------- 50 mph --------
2nd: 2.26 -------- 85 mph -------- 5000 rpm
3rd: 1.64 -------- 116 mph -------- 6100 rpm
4th: 1.29 -------- 148 mph -------- 6600 rpm
5th: 1.06 -------- 172 mph -------- 6900 rpm
6th: 0.92 -------- 198 mph -------- 6950 rpm

I think the car will still be suffering from long gears.

If you don't like the ratios, changing gear ratios is fun.

See Porsche Motorsport available gears below

Not sure I understand the complaint. The 997GT3 looks to have more favorable (shorter) gearing than the 996. This is a good thing as far as I'm concerned.

203 mph? Did someone really get a 996 GT3 over 200 mph or is that calculated?

The only benefit is the 400 rpm reduction between 1st and 2nd gear. Once in 2nd gear, the 100-200 higher rpm on upshift is not a great improvement. They have made shorter 2nd-6th gears compared to the 996 GT3, but both of them are pretty long.

Don't forget that the new car is rolling on 1.3" taller rear tires, and that affects gearing.
