Fuel. Use 91 octane? Ethanol or non-ethanol?
Seats are not made for taller folks! Any secrets
to adjust drivers seat for 6’3” driver for more
headroom? Am working on it Lexus seems made
for shorter drivers as previous Porsche’s have
more than adequate room. Just wondered if
other owners solved this issue.
thanks in advance.

I use Octane 94 with no ethanol.

 

91 - 93 Octane (whatever is premium in your area), up to 10% ethanol (so most normal gas stations).

I'm short so don't have the seat problem, lol

 

Just use premium fuel. I usually get mine from Costco.
I'm 6'4" 200 lbs and I have plenty of head room, even with the moon roof. Nobody is sitting behind me for sure because I have the seat way back and leaned back. Maybe my legs are longer than my torso compared to you. I also have a 911 cabriolet and think I have just as much head room in the RCF (unless the 911 tops down). I could see where someone wider than me might have a tight fit n between the bolsters.

 

Use premium that’s 10% ethanol. Does OP sit ‘up’? I’m 5’9” and find plenty of space in my car. Not suggesting that you lean back but if your hands are on the steering wheel 10/2 and slight bend at the elbow, your head touches the top??

 

I am 5'10" and 175 lbs. I fit perfectly with enough head room. I also have the carbon fiber roof. You probably have the moonroof, which takes out about 3 - 4 inches in headroom. The steel roof or carbon fiber room have more headroom.
