Are the Mounting Rails for 944 the same as the 911

[collier]

Hi everyone,

I have come across an item in the classifieds that I am thinking of purchasing form my 72 911T.

My question is this: a guy is selling a "universal" seat mount for Porsche....

...was last used in a 944 TurboS with a Corbeau Clubman. The mounting bracket is universal so if your Momo is bottom mounted, there is no reason why it won't fit.

To make it more simple: will a 944 TurboS seat direct-bolt into a 72 911T? If this is true, then the same adapter should work on my MOMO 1000 lakes seat into my 72 911T?

Please send help

Hi Chris,

Not 100% about this, but I think it is universal fit if you drill holes in your floor.

I have the seats from an '82 944 and they are narrower than the seat mounting tracks in my '72 911. I'm fairly sure it is the same width as the newer 911 seats (probably the same seat, in fact). Adapters are necessary.

The seat mount points in a 911 are 16" apart side to side. At least this is the case up to '89.

Not trying to start an argument, but I think the early cars have wider seat mounting points than the later ones. I think the split happened between '73 and '74.

I could be wrong on this though...

To take this one step further, I have a carbon fiber/kevlar MOMO race seat that I want to mount into the factory seat rails of my 72 911T. I would prefer NOT to drill holes in the floor for a "universal" type mount.

Is there a "universal" mount that will accept a variety of aftermarket race seats, that WILL fit my factory seat rails of my 72 911?

Maybe I should have started off with this question?

thanks,

chris

OK I just went through this on a '85 Carrera. When I was trying to figure it out somebody told be that all 911 seat mounts are the same thru '89, but take that part with a grain of salt in the following discussion. Obviously you're going to want to measure it yourself on your car.

So you want to mount racing seats in your 911? First you should know that most race seats like Sparco, Cobra, Corbeu etc all use a generic side mount system. The fiberglass or composite shell has two captive threaded holes on each side of the shell and the spacing between these holes is standardized among many brands. This makes it possible to buy a side mount bracket from another manufacturer that will work with your seats. One exception is Kirkey seats that I know of. By the way the seats I am talking about here are the shell type, none of these have recliners for the seat back. They are pure racing buckets.

Another thing to understand is that sliders are not supplied, and for these generic racing shells you have to fit your own slider setup. The sliders will go between the side mounts and the floor mounts.

Once you get the stock seats and sliders out of the car you will see the 911 floor mount sheet metal. You may also see some electronics under the seat if for example you have a Carrera the DME brain and associated relays are located under the driver's seat. On each side there is a sheet metal bracket that the stock seats are bolted to with allen bolts. The allen bolts go through the stock seat brackets and into threaded plates that come up from behind the mounting sheetmetal.

The challenge is to find the right combination of seat, side mount and slider that will fit without having to fabricate anything. You can measure the width of the seat mounts in the floor and you can measure the width of the seat. So now you need to find a side mount that will bolt up that will give the correct side-to-side and front-to-back bolt holes that work. Most side mount brackets have multiple slots or holes so there is some leeway here. Each seat maker will have it's own side mounts to sell. Many are made of aluminum and some are steel.

The combination that worked for me was the Cobra Imola II racing bucket with Sparco sliders and Brey Krause steel sidemount brackets and Brey Krause slider adjuster rod.

Hope this helps.

Chris,

Perhaps this is not the answer you're looking for, since it sounds like you want to purchase something, but it would be quite easy to fabricate mounts that would suit your purpose.

You will need two pieces of flat mild steel 3/16 x 2" (or similar) and two lengths of 1 x 1 mild steel square tubing. Use the flat stock to make plates with holes that line up with the factory mounting holes. Place the square tubing perpendicular to the plates so they bridge across from one plate to the other, the same distance apart as your seat bottom mounting holes. Weld the square tubing to the plates (gusset as appropriate). Drill holes through the square tubing where the mounting points are on the seat and then mount the seats to the tubing using appropriate fasteners. Use the factory fasteners to bolt the plates to the existing mounting holes in the car.

If you chooe to use side mounts instead - you can purchase or fabricate L-shaped brackets out of flat stock to bolt to the adapter you made and also the seat side mounts.

This sounds complicated, but is easy. Less than $10 of steel stock, some welding wire/gas and a little black spray paint.

I had a similar setup in my VW rally car, except we welded the cross pieces to the seat rails instead of bolting them. I used aluminum Recaro brackets and side mounted them (gave me more control over the angle and height of the seat). I was using Momo Acropolis seats.

Best of luck. Let me know if you need a better description.

PS. This setup is not adjustable (fore-aft), but I was the only driver in my rally car. If the co-driver needed to drive we had bigger problems than seat adjustment...

PPS. The guy who purchased my rally car bought another brand of seat (Corbeau?? or Cobra??) and my brackets had a different hole spacing than my seats did, so be mindful of "universal" brackets.

PPPS. Recaro mounting brackets do fit the Momo hole spacing, at least with their aluminum side mount brackets and a Momo Acropolis.

the seats in my 1979 924 came out of a 911SC. they will also fit my 1984 944. in no case was any seat rails modified going into or out of any car.

good luck!

I bought a set of Corbeau seats from a '75 911 for a '77 project. Over the winter I installed them in my 944 S2. Straight bolt up. I've sold the '77 and am now working on a 3.2 conversion in a '73 911. Seats do not fit with the exsisting rails. Corbeau's website has a list of rails for different cars.
I like the 944 a lot less with the stock seats back in!

Hello

Very simple

Up to 1973 Porsche used special rails and the seatbelt was attached to the seat.

In 1974 the new design came with the belts on the floor and the inner sill. Those seats where used by the 924 too.

In 1982 the seatrails where changed ( rised and angled ) but remain similar usabel in 1985 all 924/944 911 got the same seats with seat montet inner belt lock.

You can fit nearly all seats up to 85.
Your other sill support plate has to be made to fit. The inside rails must mount direct to the M8 bolts on the inner tunnel.

Most race seats will bolt onto the recaro seat rails.

I'm not sure if I should stick my two dollars worth in or not (2 cents is a little low for Porsche owners....) but I will anyway.

I have an '84 Carrera that I bought with Recaro seats installed. I recently sold those seats and put in seats from an '84 944 (leather bolsters and Porsche lettering across the seat surface).

My point here is that the bracket mounting holes were 16" apart and fit perfectly. On the 73-74 model, the mounting brackets are different but you can purchase adapters or even fabricate ones yourself. I found this out when trying to sell my Recaros. Measure measure measure. Don't take anyone's word for it. Check it out yourself....you'll be happy you did!
