M4 Seats

[Senek67RS]

Has anyone put them in a first gen Camaro? Curious if the memory is actually in the seat, like it looks, or if just the controls are there? Also curious about fit.

[billohio]

I am looking into that also. It looks like the drivers seat has a module for memory. The passenger seat has a smaller module that might just be for movement. I read somewhere that someone did this with m3 seats and they would work for like 15 seconds and stop and he thought the module would fix it. The 15 seconds was wired direct. That is off the top of my head from what I remember

[Senek67RS]

Thanks for the Insight. I am fine without the memory working, as long as I can move the seats. Would have thought that if you bypass the memory portion and direct wire the motors, they should work?

[billohio]

Most of the seats I have ran across seem to have the modules yet. Maybe salvage guys keep them together.
I will see if I can find what I read on the m3 seats. Might have been on team camaro. My bmw dealer did tell me that seats from 2019 and newer are not as comfortable. Kind of hard

That would be great if you could find that thread. Also, I do plan to go sit in a pair and make sure they are comfortable and will fit before I pull the trigger. The ones I’m currently looking at are out of a 2017.

I have 4 series convertible seats in my Chevelle. Absolutely love them and very easy to fit.
There are many threads about the electrical and what works/doesn’t.
So far I am unable to get the memory to work but have no problems with the seat adjustments including bolsters.
The issue that you will face (as have anyone else that has done this swap) is that the seats don’t stay “awake” for very long. You can get in, start the car and adjust. The moment you stop the seats will sleep until power is cut and re-sent.

What happens when they go to sleep? Does that mean that you can’t adjust them again until you turn off the power on the car and turn back on? Also, I know the Chevelle’s have more headroom than a first gen.

[billohio]

310Chevelle those look great.
I never adjust my electric seats once I get them set so shouldnt be a problem for me. Next time I am at my BMW dealer I will see what they think causes that. I do have an email so maybe I can email one of the service managers. From the emails I get they dont sound real busy right now!

[billohio]

I did find where the module uses a sensor to record revolutions to get the set to the presets. I emailed the dealer and will see if someone in the service dept can get us some info on what is happening

I have e46 M3 seats going into a '72 Olds 442 convertible, these seats don't have the power-down issue that the later model years have. I haven't gotten the memory functions to work yet, but the seats power up and stay powered up and work fine with just 12v & ground. It appears the memory module is in the seat but it requires some kind of communication via the CANbus to save & retrieve the settings. The e46 M3 was made from 2000-2006, in 2007 the next model was introduced which was an e90/93. Starting in 2007 the seat controls require constant communication with the CANbus in order to keep working. I have seen some guys overcome this with a timer circuit that sends a 12v pulse every few seconds to keep the seats powered-up. Since the M4 was introduced after 2007 I suspect it uses the same CANbus communication and the timer circuit would work.

I have attached a pdf of the M3/e46 pinout diagram incase this may be helpful to someone.

Gentlemen! I too am looking into putting M4 seats in my 69 Camaro project. Here is a link to the wiring diagram for the specific M4 seats:
https://www.newtis.info/tisv2/a/en/f82-m4-cou/wiring-functional-info/body/seats/driver-s-seat-adjustment/Fpyv9iWb

It’s great news that 310chevelle was able to install and make those convertible seats move because the M4 seats we can make move as well without a canbus.

Now the question is where can we find these seats for a decent price? I’m going to have mine recovered anyway so I don’t car if airbag is blown or leather is torn etc. just need it to be 100% functional. Any ideas where I can get a set for a decent price?

Thanks for sharing the wiring diagram! I am doing the same thing, recovering the seats and only thing I care about is that the plastic pieces on the seats aren't too beat up. I suppose they are replaceable, if I can find a good enough deal.

Getting the seats to move upon first powering them up was the easy part.
I do not think there is a way to keep them awake without a CANbus or timed circuit.

Rather than coding an arduino, I may run a hidden toggle switch that will allow me to cut the power on and off to the seats to wake them up.
It’s really isn’t a big deal once they are in place as I am the only one driving it around, but the girlfriend has been wanting to get behind the wheel now that things are coming together.

310chevelle, how heavy are the convertible seats?

@Joeko23 Have you test fit the M4 seats in your 69? Just curious, as the interior shop that is doing my car is concerned about them fitting. Which makes me pause on buying them and being stuck with a second set of seats that don't fit (already have a set of CTS-V Coupe seats).

[billohio]

This isnt exactly comparing the M4 but I have a 2016 X3 and the bottom cushion measured the same width and depth as the seats out of my 1st gens. The back will be taller with the headrest. I am thinking they were like 37 inches from the floor to the top of the headrest. It looked like there was no problem getting them bolted down with new bolt locations. I think my X3 is synthetic leather, I am not positive but I think the X3 could be leather . There were 2 slightly different X3 seats. Mine have the front piece that you can pull out and put under your knees. I thought they were a bit hard when I got the car but you can adjust them to really fit you. 2 lumbars and bolsters. I had a new accord I got rid of and I could hardly get out of that car some days. That went away with the X3. So, what I did this week was get a set of seats out of a m340i. The bottom measured the same as my X3 and the guy I got them from said they were the same width as corvette seats he has in his 67 Camaro, about 20 inches. His Corvette seats might be 5 years old. He did say he had a set from a 5th gen camaro and they were a bit too wide for his liking. There is a set of black X3s on ebay near Fort Lauderdale. I dont know the people and was interested in them when I was in Florida but never had time to go look. They are out of a 2019 with low miles. Looked very nice. I have a feeling a lot of the smaller BMWs have a similar size seat. It will be a bit before I actually get to put my seats in but looked like they should work. Sorry this is long but wanted to share what I have found.

Thanks for the insight. I think the M4 seats will work and am looking for a set now. Once I get them and test fit them, I will report back on fit.

Senek67RS, I have not bought them yet so I haven’t fit them yet, but. People have mounted the e46 bmw convertible seats in the first gen Camaros. I then read on the bmw forum that the F80 seat is pretty much a direct bolt in for an e46. So my assumptions since they are pretty much a direct bolt in is that the seats are basically the same size.

Why couldn’t you get the CT’s-v seats to fit?

I was also looking at the camaro seats 13-15, they have a really nice recaro version that was available for the ZL-1 and z28 Camaros but those seats are too wide. I had a 13 zl-1 and those seats are pretty wide.

the base of the seat on the CTS-V seat is too tall. Love those seats and they are recaros, but probably the most comfortable ones I’ve sat in to date. I am just going to pull the triggern on the M4 seats, worst case scenario, I’ll resell them.

I got the regular seat. The overall seats are different in look convertible vs. coupe, I happen to like the coupe look better. While I would prefer to have an integrated seatbelt instead of a seatbelt hanging down, just liked the look too much :)

[joeko23]

Agreed, the coupe seats look way nicer and more racey. I bought a pair off eBay as well. The guy said he is shipping them out Friday. So hopefully I’ll get them soon.

I would suggest using the 1 piece headliner from TMI to get a little more headroom though.

I got my M340i seats today. They are out of a 2020. The base bolt holes measured 16.5 wide and 14.25 long. My x3 (still in car, bit hard to measure) were 16 3/8 wide and 15.5 long.
I got the back seat also and it's about 2 inches narrower than my 69 Camaros.

I just installed a pair of M4 seats (non convertible) in my 69 Camaro. They fit great. I can’t figure out how to make all seats functions work though. I connected the thick red/brown wire to positive and brown wire to negative this only moves the seat forward/backward and up/down.

Could someone please let me know how to make the seat recline, bolsters, and the button on the back of the seat work (I think it moves the seat forward and backward)?

Thanks

Rodney,

That was some great information. I recently purchased a set of 06 E46 seats for my 71 Cutlass convertible. I wanted the integrated seatbelt over the factory seatbelt. I noticed the floor isn't level when removing the factory seats. Do you have any pictures or advice on how you mounted yours?

[cdrod]

Freddy:
The A-body floorpan is not as flat as the F-body cars, and the frame rails intrude into the cabin at the door openings. The mounting rails of the BMW seats are flat (in the same plane) but not centered under the seat, the outside rail is much closer to the seat edge than the inner rail. The location of the BMW mounting rails combined with the A-body frame rail intrusion pushes the seats about 2" off-center relative to the steering wheel. To remedy this issue, I made some support brackets that raised the seats about 1.5" which allowed me to mount the seats further outboard. I compared the bottom cushion height between the BMW & Olds bucket seats and the BMW seats at their lowest adjustment were several inches lower than the stock seats, so (I reasoned) raising them 1.5" would not make them any higher than the factory seats.

One very important thing to remember when making this modification. In a collision/accident, the factory OEM seat mounts were only strong enough to hold the seats in place (not the occupant); because the seat belt is built into the BMW seat, the mounting points need to be strong enough to hold the seat and the occupant! The mounting locations must be reinforced to securely hold the seat & the occupant in a collision. I welded large 1/8" thick washers to the bottom of the floorpan at the front mounting locations. To distribute the load at the rear mounting points I plug welded two layers of 4"x6" 16ga sheetmetal that overlapped the factory cross brace, I then welded a 1/8" thick square washer in the center of the 4"x6" piece. I used weld-thru primer and seam sealer on the edges of the mounting plate to protect from the elements.

I've included some pics below. Don't be too critical of my welding skills: it's not easy to MIG weld upside down...lying on your back-lol.

Bill... Have you progressed since you posted that picture? Curious to see the final look, and especially curious about how you adapted the rear seats. How tall and wide are the M340i front seats? A semi-local guy who does a lot of BMW seat work said they were 24" wide and I think... 39" tall? The stock 69 Camaro seats are about 21" wide at the bulge, 19" in the front, 18" at the rear. I kinda wrote the BMWs off but I guess its model specific.

I have some pics of what I did on a few pages starting here, I went with Planted brackets for mine. https://ls1tech.com/forums/conversions-hybrids/1324170-ls1-200-4r-l92-t56-71-chevelle-convertible-now-gen-v-lt1-6l80e-swapping-20.html

Ultimately I sold them because I wasn't confident that any number of washers or layers of sheet metal would stand up to the force from a 200lb person and these heavy ass seats going from 60 to 0 in an impact.

I have sorta progressed lol. There is an area on the tunnel that stuck out, like a factory indention that sticks into the side of the seats, that I cut and layed flat so it gave me more room. Where the BMW seats have bolt holes, the inner rear one was right over an indention in the seat plate, so I bought a 1/8th thick plate I am going to weld nuts for the seats on and then weld to the factory seat plate. I think it will work, I just have not gotten anymore done. We did hang the car on the rotisserie today and I have been smoothing the subframe welds.
I may end up using the material off the BMW back seat to cover the camaro seat. I have a local upolstery guy working on another set of seats and he acted interested in helping get the back seats done.
I had a seat in the garage and gave a quick measurement. The BMW seat frame is about 17.5 inches in the front and the rear is 18. The widest area of the bottom cushion looks about 18.5 inches. There was not much difference compared to the stock camaro seats. They are taller with the head rest compared to the 68 with no headrests. I may ask the upolstery guy if we can cut the head rests down a bit.
I sold the 2016 x3 I had and did think they were a bit narrower than these 340i seats especially the frame rail width

310chevelle,

The M4 Convertible seats look great in your car, which is why I bought a set. I noticed when I sat them in my car they are a little off center of the steering wheel. Did you notice the same thing, if so how did you correct this? Do you have any pictures of how you mounted the seats you can share?

I finally figure how to get the seats to constantly work from watching several youtube videos and browsing the bmw forums. Now I just need to get them mounted some way. Any additional info and pictures on mounting them will be great.

Thanks,

I purchased a set of BMW 4 series convertible front seats for my 71 Cutlass Convertible. I have found a couple of issues already.
1st- Seats are about a inch to 1-1/2" off the center of the steering wheel.
2nd- Passenger seat moves in reverse when prssing the switch up/down or forward/back
Has anyone had this issue? I added a clip of the seat operation as well.

Can you clarify why the seats are off Center from the steering wheel. Is it because of the mounts to the floor pan? Can this be adjusted by building some adapters to move the seat to Center? Is this a problem on both drivers and passenger side?
Im looking at installing the M4 seats in a 69 Camaro Convertible because of the integrated seat belt. Did you solve the wiring issue?

[chuckd71]

The seats are off because of the way the floor is shaped. To get the seats low enough to be useful for anyone over 5 feet tall you have to either cut into the car and then reweld a space for the seat frame or simply leave them off center. You can use planted or similar brackets, but you'll end up with higher seats. BMW seats are great, but without cutting the floor the slight compromises in position, and lack of a really good way to mount them in a truly secure fashion, were enough to make me sell them. I had them in a convertible chevelle

AB69Z:
The offset is the result of 2 issues; the floorpan on the A-body car is not flat like the F-bodies because it needs to clear the frame rails, so the A-body seats have the mounting tracks closer inboard to clear the rising curve in the floorpan at the door jambs. The outside seat rail on the BMW seats is much closer to outer edge of the seat; this is where it interferes with the A-body floorpan and gets pushed off-center.

Look back at post #37 where I installed a pair of e46 seats from a 2001 M3 into a '72 Olds 442 convertible. I welded up some brackets out of 1-1/2" flat steel to raise the BMW seat high enough to overcome the floorpan curve. This allowed me to shift them to the outside enough to be centered on the steering wheel. The BMW seats are rather tall and I was concerned about the overall height if I raised them higher. Fortunately, the bottom seat cushion of the A-body seat sits taller than the BMW seat so a 1" tall bracket puts the BMW seat cushion at about the same height as the factory bucket seat and the headrest is only a little higher than the factory seat would be.

Passenger restraint is significantly different between these two options. The original mounting points for the factory bucket seats are only strong enough to hold the seats. In a serious accident, the passenger is restrained by the SEAT BELT mounts. Look closely and you'll see the seat belt mounting points have heavy gauge steel plates welded to the sheetmetal floor pan and use a 1/2" bolt whereas the mounting points for the factory seats only use a 5/16" bolt. In a crash, the BMW seat must restrain the passenger as well as the seat so there are 6 14mm bolt holes in the seat rails to secure them firmly to the car body. When retrofitting these into an older car, you MUST reinforce the floorpan at the mounting points otherwise you're likely to imitate an ejecting fighter jet pilot in a serious collision; flying through the air still strapped to your BMW seat only without the parachute landing!

Does anyone have a printed copy of the M4 wiring diagram, the link to the website provided was shutdown by BMW

I just reversed/switched the positive and negative wire on the motors

[Camaro LT4]

Can you tell me what connections you made to power up the seat, I can’t get the lumbar or bolsters to work

[joeko23]

The M4 seats need to have a timing/pulse circuit otherwise they go to sleep. Check out this video. It’s what I did. I used the timing/pulse generator and everything works. I had to play around with that screw on the pulse generator to get the seat to always be awake but it works. I bought the timing/pulse generator from Amazon and it came in a 5 pack so I have 4 left over. If you want you can have one for free. Just pay for shipping. Send me a PM if you want it or have other questions on how to make the seat work.

I'm waiting on my seats to arrive for my 69 Camaro convertible project.
That would be great info to have.
