[Carrera3.5L]

Yes, the 3.2L Carrera ratio is 3.44:1. Porsche AG makes a couple of "sport" ratios, an 8:32 (4.00:1) being the most "popular".

Andial sells these, but they are not cheap. Last I checked they were about $2,500. Factory quality but you pay for it!

David Brown in England as well as Hor Technologie in Germany both make final drives for various Porsche applications but am not sure that they have any ratios available for the G50.

EDIT: I just reread your question, these sport ratios aren't taller but actually shorter. The 8:32 is 14% shorter then stock which means faster acceleration around town but with a loss of top speed (if that is important to you). The other ratio that Porsche offers is 26% shorter, which will be WAY to short for street use. PM me if you would like the Porsche part numbers for either of the above.
