If one were to replace a Tiptronic with a 6-speed, would you prefer a G50/21 (C2) or a G50/31 (RS)?

Engine around 280-290hp.

Depends on usage, while they mostly have very similar gearing the /21 is more street oriented w/ street internals and lower 1st, the /31 is more, but not fully, track oriented w/ some track internals and a taller 1st

in order less to more track oriented street transmissions

Too expensive .

The /21 or the conversion in general? The conversion is close to 10K euros if you have it done, whatever gearbox you buy doesn't really change that.
