First, for all you seasoned drivers, I'd love if you'd lend your wisdom on driving position by filling out the following prompt (if you have the time):

How do you set your:

1. Seat Distance From Front:
2. Seat Height:
3. Seat Back Angle:
4. Steering Wheel Distance:
5. Steering Wheel Height:

I've been working on the correct seating position in my C2S, and while I think I am closer to having it fully dialed, I'm still not confident I have it quite right. To start, I am taking into account the following:

1. Arms with just a bit more than a 90 deg. bend with hands at 9 and 3, with shoulders fully against the backrest.
2. Hands can be draped over the steering wheel fully with wrists resting on the wheel, with shoulders fully against the backrest.
3. Wheel can be turned 180 deg. with both hands at 9 and 3 without shoulders leaving the backrest.

To do this, I've had to move the seat up much further than I am used to, to the point that my knees are pretty well bent, and I still have room to extend my right leg even after the brake pedal is fully depressed. I mention this because what I have read so far indicates that there should be a slight bend in the knee after the brake pedal is fully depressed. My knee bend is quite a bit more than "slight."

Furthermore, I've kept the back of the seat bottom in the lowest position possible while also keeping the seat back much more upright to help my arm/hand positioning meet the above criteria, but my lower back gets sore well within an hour even with lumbar support provided via 18-ways. I've chosen to relax the seat back positioning a bit just so I can enjoy myself, though I an sacrificing being closer to the steering wheel a bit. I should also mention I have the steering wheel fully extended. I'm unsure how to best set the steering wheel height at this point.

All that said, are there any tips that other drivers might be able to lend when it comes to seat positioning? I've done a lot of research on this, but still don't feel confident that I am in the sweet spot with where I have everything. I do already have a couple of less-aggressive setting for setting 2 and 3, but I'm trying to get setting 1 just right for more aggressive driving.

FYI, I am 6', 170-180 lbs, with relatively normal proportions in terms of leg/arm length. I do have almost no butt, so some of my lower-body discomfort could just be due to my butt falling asleep which might happen in any car.

 

Same problems, same height and build, no solutions but wanted to say I'm curious if folks have any useful info that may help.

 

Patrick Long gives a brief "how-to" in this video. The actual distances will vary depending on the individual, but the geometry should be the same (more or less) in any Porsche.

 

Like they say “it depends”

my normal comfort driving position is arms stretched legs stretched.

a couple of years ago I completed the Mercedes AMG driving school at Road Atlanta

the “professionals” wanted me closer to the steering wheel - arms bent legs bent.

This to me felt very strange but the pros said it provides more control 😎🇬🇧😎

 

This is the Porsche made video I advise people to use. Another poster linked to one by Patrick Long, this one is a little more generic. You will find the driving position annoying at first, most people are way too far back.

 

Is this for track driving or street driving? You probably wouldnt find optimal track driving position too comfortable to tool around town in. For track driving you would generally want the seat as low as possible (while not obstructing your forward view) and forward enough to fully depress the brake/clutch ALL the way to the floor while still maintaining a bend in your knee. Also would want to maintain ample bend in your arms while gripping the steering wheel and be able to fully turn the wheel lock to lock while at a 9 and 3 hand position. While this maximizes control and safety at the track its certainly not necessary for the street nor the most comfortable.

 

I’ve been using this. Seems to work well.

 

Happy I learned how to adjust my seat when I had my learner's permit to avoid this issue prior to my first 911 purchase (or any car for that matter). Whew!

 

There's a difference between a comfortable seating position and a proper one for, as you say, "aggressive driving."

For daily commutes, just set it up so that you're comfortable, which seems like you've already done with buttons 2 and 3.

If you're looking for a seating position that is proper for "aggressive driving" (i.e., an HPDE or AutoX event), you'll want to be closer to the wheel than you normally would, so that not only do your wrists drape over the top of the steering wheel with a slight bend of elbow, but they should be able to drape over the top fo the steering wheel even when you're elbows are bent close to 60 degrees. Same with your knees. Depress the brake pedal all the way, and at that position your knees should be bent around 60 degrees.

It's going to feel strange, but sitting that close to the steering wheel will give you the most control over the car's controls (wheel, gear shifter (either paddles or MT stick), the pedals (either both or 3).
