987.2 gear ratios
 
Does anyone know the max speed in each gear for a 987.2 (ie facelift Box/Cayman)?

Thanks!

Have you had a look at the gard transmissions website ?
They normally have different models listed and you can then plug each gear , r$p , max rpm , and tire size into a calculator to get speed and work out drop etc .

I might have them at home .
Will look later
