Default FAT GUY wants bigger seats Possible???

FAT GUY wants bigger seats Possible???,

I am 6 feet 300 pounds and My body is such that I have short legs and a long torso. So the seat back feels short- It hugs me in the wrong places!

Anyway to Correct this ????
( hello Champagne!!)

Is there another LARGER /TALLER PORSCHE SEAT.

Ideally I would like a Mercedes S class seat or at least on from an SL500

ANY TIPS_ BESIDES SURGERY AND LOSING WEIGHT!

On my '81 I thought I had a special driver seat. It was definetly wider on the bottom and very comfortable. Further inspection (seat removal) found that the side bolster was bent badly to the point of breaking. I removed the side leather and welded back into original place. You might be able to remove leather and bend the bolsters out a bit. This will tend to stretch the leather at the seams so you would need to be careful. By the way mine was the old style seat. Hope this helps.

Couldn't you find someone to modify a pair of S class seats to bolt in? Seems like something a talented fabricator could take care of.

Later models may be different, but your seat should go forward and backwards far enough to get those bolts out.

The rear bolts are easy with the seat slid all the way forward, a 6 mm hex socket on a ratchet should be fine. The front bolts are tough even with the seat all the way back- I would try a 6" (12"?) long 3/8" extension on a 6 mm socket to get the front- you'll end up compressing the front edge of the cushion to get the socket & extension upright. Stick a towel between the extension bar and the seat so it doesn't chafe the leather. And if you've got it, you're less likely to strip it if you use an impact wrench to loosen. They're TIGHT from the factory....

What year is your shark Joe?

As a general rule, both the older style and the newer one are extremely well structured seats and thus, excellent foundations for modification and customization. Within reason, either style can certainly be made to work for you a lot better.

I need a similar mod on the bottom cushion for mrs dr bob. Just a little extra in the middle section would keep the side bolsters from squeezing. Is it possible to just add a layer in the middle under the existing cushions and covers? That would make the seating part a little wider, effectively.

Hey Bob,

although that is one way of doing it, it would not be my recommendation unless you were doing new covers. The insert and side bolsters are sewn together and lifting the insert would change the fit of the bolster.

While doing new covers, the relationship between the insert and side bolsters can be addressed and compensated.

The following pictures show the result of such an attempt by what appeared to be a professional shop:

The seat is from an OB. And this is what it looked like when I got it:



For some reason, the bottom of the seat had been layered with a piece of carpet:


Once I took it apart, I found that they had slipped 2 pieces of 1" dense foam between the main seat foam and the springs:


In the long run, the seat lost all of it's shape and the result was that first picture.

This is what it looked like once it was properly restored:

That's why I try to ask before I do something stupid. I was thinking that -maybe- 1/2" to 3/4" would be ok without too much grief. That seat you show looks like it would spill you out way before you even started the corner. Amazing what folks will sell as an improvement.

It's hard to believe that last picture is even the same seat. Nice job Paul!

Paul--

Looking at that carpet layer in the bottom, I suspect that was added to keep any old deteriorating foam shreds from littering the area under the seat. Several of my 20+ yo cars have suffered from foam dandruff after too many years in Cali summer sun. Many early cars had muslin there, but in the end the muslin gave up too. I have yet to open a 928 seat though.

Interesting to see how seat structures have improved since the early days that I know. The last set of seats I remanufactured were from one of my early roadgoing Lotus Europa cars. Just foam with a vinyl covering from the factory, and used steel rods to back the details. Steel rusted, seat cushions lost their shape. Replaced the original coat-hanger wire with stainless TIG rod during the replacement process. Whole project was done in an afternoon. The 928 seats look like they may be a little more involved...

To Eurocarlover, if the seats wont go forward or back enough to reveal the lower connection bolts in the seat rails get a helper and have them lift the front or rear depending on direction of the seat, as you move it back or forward.
What happens is that the seat rail bolts get loose in the bottom of the seat and unscrew enough to hit the rollers inside the seat rails and thus limit the amount of travel.
Once you get the seats out it is wise to remove the seat/rail bolts and put some loctite on them
