Hey guys! First of all, I don't really know where ask/start this topic, sorry if it isn't the right place for it.

So my question is has anybody tried to replace the 145's seats (front and rear) with the GT seats?
For me, the 145's seat is ~comfortable, but.. in corners it doesn't really supportive. To compare with my father's 155, those a lot better.

I tried to look after which car's seats would be perfect (both for holding me and for "design"), and I find that the GT seat would be the one.
(For example, GTV seats don't supportive enough, and as far as I know, it doesn't have airbag)

And if everything is fine, the GT seats would fit (with some tricks ofc), what about the airbag? Is it compatible with the 145?


I saw maybe only one topic that someone tried to do this but only with the front ones, but I don't see anything about the airbag question, and the rear seats.
Or if you could recommend me anything else, go for it.


Thanks guys!

Hey Lecram,

there are a few threads on seat swapping, but people's interest seems to be in the front seats.

I don't recall reading about a rear seat swap, but I wouldn't have expected that to work. The front seats stand 'free' within the car, but the rear seats 'interface' with the shape of the vehicle and are likely to be critical.

As for airbags- I don't know too much about that. A lot could be derived from the schematics of course; I know that across the two systems used for the 145 /6 both have two-wire leads going to the bags themselves.
If you look at the schematics for the GT, it should give an idea of whether it is a similar system.

I have to say; because of the age difference, I would be surprised if they were compatible.
You might have to import the complete electronics from the GT, but having done that for the seats, you might have trouble with the accelerometers which live in the B-pillars, behind the seatbelts.
The 145 /6 have sensors to determine side-impact velocity (the wiring is wrapped in yellow, if you have the carpets up), and that might be another level of compatibility again with the GT system.

The wiring diagrams should tell you a lot.

Pretty sure this won't work - one of our other members tried this recently with 147 front seats, which are the same (scroll to the end of the article):

http://forum.alfa145.com/index.php?showtopic=19077&st=0

As for the back seats - again, I'd be very surprised if this would work as per Dante's comments above.

But if you want to try it, GT or 147 interiors are cheap to buy...

all of this of course, is before you get to interfacing with the airbag-light on the dashboard.

I don't 'know' this (but Jeremy would) whether the GT even has discrete wiring & electrical systems (actual circuits & lamps like the 145 /6) or whether it's a Canbus system of completely different makeup.

It could be that the airbag light 'output' on the GT controller is a data-output, rather than a voltage, or grounding line.


The airbag light of course is an MOT thing that has to be seen to illuminate and then go out again...


You might be best lecram, to import the GT seats and accept you'll have to live without the airbags. Just don't crash.

Good point - yes, the 147 & GT both have the CAN bus interface

... and I should also say, I have both a GT and a 147 at the moment, so if you want me to measure and/or send photos of the seats then just let me know...

I tried to swap in my 147 1.6 TS Lusso seats into my 145. I discovered they are very different. The seats rails are much wider apart. Even if you decided just to bolt one side of the rails in, which would be insane of course, the rail bolt holes don't line up with the 145 floor pan seat holes. Finally, the part of the seat where the knees locate is so high that the seat cushion touches the steering wheel. They are a completely different fit. I would imagine the GT seats will be a difficult fit. Make sure you try before you buy.

Wow. I simply just don't believe that I get that much of help. Really thank you guys! It's awesome.
(I thought maybe after a month I'll get a few answers, like 'u can't do it' ...)

Yes, I think you convinced me. I'd would be to difficult, and I think it doesn't worth it.
Never mind , I can live with those seats. (Maybe I'm gonna search for a Special Edition interiored 145, I really like that black-grey dark interior.)

And JeremyG, I'm really appreciated for that offer, thank you!


Again, really thank you for everyone! smile.gif
Have a great holiday, and merry-merry Christmas for everyone! worshippy.gif worshippy.gif

Edit #2:
Maybe can you guys suggest me a good alternative (for the seats) which is a straight swap, and more comfortable and overall a better seat than the original?

Merry Christmas to you, too!

One other thing you should consider - there is a fairly simple mod to lower the driver's seat by removing the height adjuster on the seat base.

This improves the seating position, and makes you feel as though you are sitting in the car, rather than "on" it. This doesn't improve the way the seat holds you, of course, but you do feel more secure woith the lower seating position.

There are articles on this forum as to how to do this - look under the "How To" section:

http://forum.alfa145.com/index.php?showtopic=12002

I noticed there was also an article on fitting seats from a 156 (readily available) in a 145 with a small modification:

http://forum.alfa145.com/index.php?showtopic=19207

... might be worth considering?

Yes, seat lowering already done. It is much-much better for sure, but yes, it still doesn't hold me well enough.

But the second article is about fitting a 4 (or 5 , I never knows:D)-door car seat (from the 156) to a 5-door car (to the 146). I mean in this case, you don't have to fold the seats to let the passengers sit to the rear seats.
So if I would get the 156 seats, they won't have fold."function".

And - let me know if I know badly - the 156/147/GT seats aren't the same? I mean as Ganz said, the 147's seats are much wider but this post you mentioned (about the 156 seat to the 156), it is a "straight swap". So the GT seats rather like the 156 or the 147?
Sadly it doesn't really matter because I'd like to have airbags. rolleyes.gif

The 156 seat article.. they look like GTV seats not 156 seats. I have heard of GTV seats fitting the 145. 147/156 GTA.. I'd be shocked if they were even a close fit. The other thing to consider, as much as I was disappointed the 147 seats did not fit my 145 I was actually OK about it in the end. The reason being: those 147 seats weighed a ton!
