brake
left foot: clutch in/ right foot: roll ankle from brake to throttle.
downshift
release clutch/ get on throttle fully

I think that's right....

I don't downshift nearly as often in the Boxster as I used to with my old Miata.
Usually in a turn I just wait let the car slow down until the revs are 2K or lower, quickly slip into neutral, tiny blip and shift into 2nd. Kind of the lazy way to do it.
