Bucket seat positioning

When dealing with fixed bucket seats, what are recommended settings for tilting the bucket seats.
Having them perfectly level feels weird and like I'm too upright. I then tried them slightly tilted back which felt better.
When looking at OEM cars the back rest seem pretty angled back along with the base being angled back so the back of your legs are supported.

I feel comfortable in my seats but my spine doesn't feel as supported and if I did a full day at the track I feel like I would run into issues.

I wouldn't say there were any recommended settings.

It's whatever feels right for you and/or is safe.

You're 'supposed' to be as upright as possible with your arms at a 90 degree angle and your wrists should be able to bend over the top of the wheel.

Like yourself this wasn't comfortable for me so I've got mine as tilted back as possible.

This is how mine will be once the pedals are mounted but the column welded instead, spacers purely to mock up

I guess that driving with the arms at 45 degrees is even more awkward. Surely they mean 135 degrees? 😆
135 degrees of elbow flex would be essentially touching your forehead :ROFLMAO:
Unless you're measing with your arms flat by your sides. Then you'd be correct

With arms out, 45 degrees is about right.

No it's not, that's what 45 degrees is. ;)The angle in the picture in the article is more like 135 degrees.
Kinesiology and flexion studies would tell you otherwise.
What they're depicting is elbow flexion, which is measured in reverese essentially...0 degree being out infront of you 180 degree being behind you.

I don't know expensive words like that. 😝 But in that case the drawing in the attached article is wrong.
It's actually correct :LOL:
Take the red axis point for the elbow and apply it to the verticle line on the diagram in the article, then follow the elbow line to the hands (remembering 0 is hands straight infront of you, 180 degrees is arms/hands behind you) and you get roughly 45 degrees.

The diagram below explains flexion, to some degree...:ROFLMAO:

The picture doesn't show any relation to the vertical line? All I see is an angle saying it's 45 degrees, and looking like 135 degrees. This is my last comment about this, as I don't want to ruin a thread about a good subject. ;)
I will be installing my seat in my car soon, and I'm interested in what angle I will get it in. If I remember correct, I had them pretty upright in my old G40.

Doesn't it? Pretty sure there's a big red vertical line.
You're right though, it is a good subject....for those with a basic understanding of maths and trigonometry ;):ROFLMAO:

Great. I saw that Skoda picture and I seem to pretty close to it's recommendations.
While on the subject. Has anyone experimented with support pillows? I'm thinking some lumbar support may assist, I quickly read a aper and it seemed to indicate that increased lumbar support led to more comfort which should lead to better concentration over time and therefore better driving/reduced lap times.

Corbeau do inflation cushions for lumbar support on their seats.

Other manufacturers may do too.

Nascar, wheel very close, more upright

Rally, wheel lower, upright

Lack of lower back support is a major problem with a lot of seats I see - a flat bit of board for the backboard? Really? Because our spines are a straight line, are they??

Racetech seats are the only seats I've seen that actually resemble the human form without the need for extra cushions.

Yes exactly that white16valver. I definitely think mine need lumbar support adding (bimarco) as they are flat backs.
