[Perfectlap]

when the first few positions are seperated by mere tenths, it's really not all an advantage to downshift in this car. Unless you are PERFECT it will probably cost you time. Probably wiser to experiment with a different line, braking sooner/later, etc.
I don't think I have ever downshifted to 1st in the Boxster, there was a guy in one autox club that would do it in his S2000 and I would just cringe every time I heard it.
