It is a sweet sound when the Boxster is wound up. So happy to see people who want to drive their Porsche as if it were a
Porsche! Most people baby them and they start to sound horrible, like an old Chevette.
Like others said, just be careful on the down shifts. As you shift
UP the gears, make a note of the speed when you get to the 6K rpm range. I don't have a '99 so I'm guessing it redlines at 7K like the '00. That way you know your are safe when down shifting to second at 30mph, etc. There may also be a top speed listing for each gear in the user's manual, but I'm not sure. They have it in the 928 manual and it was pretty neat to see it can go 135mph in 3rd gear (not the Boxster so don't try that please).
She likes to be driven hard so enjoy!!
