M37 Seat Mods

[hulk1602]

So I've had the car for nearly a year now and still love just about everything about it with the exception of the seats. I just can't get used to the lack of thigh support. It's causing lower back pain and just isn't very supportive (constantly feels like i'm sliding forward). I've been using a cushion under my knees and lower thighs and it does help but I'm looking for a more stable and permanent solution. I don't want to get into modifying the cushion itself, but if there was a way raise the front portion of the bottom a couple inches more I think it would be a big improvement. With that said I'm going to try getting underneath it to see what can be done to raise it. Has anyone had these seats out or has any insight as to this being possible? Thanks in advance for any info.

I actually wish the sport seats would go lower...they seem so high.

I get bad lower back pain too on long drives and i'm young still 17 lol my dad lets me drive it . I didn't know what the cause was though so maybe i'll try a cushion next time thanks.

I have on occasion have had back pain a little on long trips from Ga to Texas, as far as how low they go, they go low enough for me, I'm 6 & 1/2 and 213 pounds of pure power

I can see that on a long trip like that no matter how good the seats are. For me it's not the height but more the angle. Doesn't tilt me back far enough so my legs are dangling, and I'm not that tall either ( 5'9" 200 lbs of hard earned dad bod )

I rather have the seat out of the Non sport as they are more comfortable. I rode in Armybrats Non-sport and feel in love with the cushion on his seats. I take some rather long trips in my M56S and those sport seats which I don't consider sport at all are very uncomfortable. The seat goes down pretty low for me and I have to raise mine up to see the road lol. I'm 5'9" by the way.

So you just want the bottom cushion to come up more in the front? Or farther forward too?

Used seats for the Y51 can be had for around $300 so modifying them might be less scary then you think. At 6'3" I always want more under-knee/thigh support up and forward. I wish more cars had adjustable thigh supports like some BMW do, where it can be pulled out for longer legged drivers.

I always imaging making a Z shaped bracket that I could attach to the seat with cushion for my knees/thighs. A non-adjustable version of what BMW offers. But I digress.

Since I think you just want to go up you have two rather easy (IMO) options that I can see looking at a burnt out Y51 lower seat from eBay (HERE).

Option 1 - Add spacers to the front bolts of the pan that the cushion secures to which will raise the front up.



Option 2 - Add spacers to the front seat bracket where it bolts to the floor which will also raise the front up but the bolt angle will probably get weird.

I would love the bottom to move forward independent of the seat back and that would also resolve the issue (some cars have this adjustment, like the LS, and it essentially works as a thigh support extension, but I don't think that's possible in this case). What your suggesting with the spacers might work and that's exactly what I was thinking once I get under there. If it does and I can keep the seat essentially stock but with a little extra hardware underneath that would be ideal. Great find with those pics that helps a lot, thanks!

No Prob.

You can probably move that pan forward some too pretty easy with a few more holes. Not adjustable on the fly but should be better then it is now.
