I'm hoping to buy a used S, perhaps in the spring. So I was test driving this weekend and it was everything hoped for.

I also did a "broomstick test." With the top down I put a broomstick from the top of the front window to the roll bar behind my head. The broomstick was touching my head, so I deduce that if I roll (god forbid), I might not lose brain matter but I would be a bald man. BTW, I am 5'8"

So is there a taller roll bar, or shorter seats? What are my options here? Or am I a paranoid freak?

I'm not intending to race, but I'm sure I'll hit the track and twisty back road as often as I can.
