the perfect seat adjustment

I cant seem to find the perfect seat position. I read in a performance mag that your suppose to see over the wheele and not so high up where you see the nose of the car idk. How do you guys get that perfect adjustment im not super tall or over weight. C2s stock seats.

1 - Raise the seat height just enough so that you (obviously) see over the wheel. Tall people should leave a gap under the headliner.

2 - With your left foot firmly planted on the carpet/firewall behind the clutch pedal (or brake pedal) adjust the front to back distance so that your leg has a slight angle.

3 - Adjust the steering wheel position as low as comfortable without blocking instruments' view (or being bumped by your knees during pedal operation. Pull the steering wheel towards you just enough so that your arms (with hands at 9-3) are bent about 90 degrees and are in a comfortable position.

4 - Adjust the angle of the seat-back in such a way that with your arms stretched over the steering wheel (at 12h) your wrists are aligned with the top of the steering wheel. This seat-back position should be fairly close to vertical with just a slight tilt back. Your upper back should always make good contact with the seat-back in a way that rotating the steering does not separate it from the seat.

Drive with your hands at 9-and-3!

Note: this is how I drive and learned it long ago from Vic Elford's book - Porsche High Performance Driving Handbook and also from PSDS coaches.

I had the perfect seat adjustment and wiffy and I drove across the country, one day I was tired and she drove, when she readjusted the seat and saved it, she deleted my setting.
I am still searching, a year later!!!!!

in proper performance driving position you back must be in full contact with backrest of your seat when you turn steering wheel 180 degrees.
i usually move seat forward to point where my left knee touches console (while left foot sits on a clutch) then I move seat back so i have about of an inch of space between left knee and a console.
seat of couyrse goes to lowest possible position. you want center of gravity to be as low as possible. for sports backrest goes almost vertical, or anywahre between vertical and 20 degrees from vertical, depending of how comfotable you are.
for highway i just recline it a bit more. steering wheel height should be positioned in the way so when you put your arms on top of it touching front console it makes a horizontal line - your palms are resting on a console and arms touching steering wheel. at no time your legs or you arms should be straight during driving, there is always some angle in joints or you can hurt yourself. also, try not to 'wrap' your thumbs around steering wheel or severe hit may dislocate them.

I'm pretty close to what you guys are talking about, but I'm always surprised when I get into a car with sport buckets, such as a GT3, and I feel like the seat back is reclined. Anyone else notice this? It almost makes me feel like I'm sitting too upright in my current car.

Paul,

Do u use this position for autocross or DE or both? In my mind right now I would say that position would be way too close for me for DE but I don't know your height.

i do not know an alternative way to adjust seat so procedure is same for me. i am almost exact 6ft.

as of how close seat should be to a steering wheel - in a race prepped car you cannot really get into seat without taking steering wheel out first.

try to get into one and see how they put a seat in and how your arms 'wrap' steering wheel and where your elbows will be. arms must be bended almost close to 90-120 degrees in elbows, imho, if you are closer to 160 degrees you do not have enough leverage for fast corrections.

different people have different preferences of course, when I was first introduced to the way how seat should be configured it looked and felt very odd but then i kinda got used to it by now and cannot drive else.

but i also cannot drive on a highway not having beckrest reclined to 30-40 degrees, normal 15 degrees recline is too vertical to survive for 2 hour drive for me. again, on a track i just adjust it so my helmet has about enough of space to fit my hand between roof and helmet top.
recaro seat i have sits a tiny bit lower than stock seat but it is still on sliders, if i would bolt it to the floor directly it would be much better probably - about of 1.5" more of vertical space, maybe i will do it some time later.

sport buckets assume you use helmet with hans. when you get 20deg HANS device on it will move you to almost vertical proper position.
