Sport Seat Rails

Post by passta »

Looking to rebuild the bases, or really as much as I can/need to of my manual sports seats, Euro 85 M635csi LHD. The leather and cushions are all new but they are pretty sloppy mechanically with a lot of unnecessary movement, the driver's seat is somehow slightly twisted off-center so when driving I am angled horizontally to the right enough that it's annoying. Being 6'4" tall there is not much space regardless. I'm trying to understand what parts I would need and am confused about the inner/outer, left/right rails and which is needed for which seat.

Looking at realoem, https://www.realoem.com/bmw/enUS/showpa ... Id=52_0130

Am I correct in thinking I would need the following rails?

Drivers Seat
1 Outer Left
1 Inner Left.

Passenger Seat
1 Outer Right
1 Inner Right

Or is it like this?

Drivers Seat
1 Outer Left
1 Outer Right
1 Inner Left
1 Inner Right

Passenger Seat
1 Outer Left
1 Outer Right
1 Inner Left
1 Inner Right

Is there a more effective way instead of replacing the parts to tighten up the seats? In looking at them, there is nothing cracked or broken that could be welded that I am seeing so far. Headed to Sharkfest in April with my 12yo son and its about a 300 mile drive for us so I want to make sure its safe, and comfortable.

You can try to see if Elias Gergy thru face book has frames in good shape.

I'm fine with buying new as they are available, but not sure what I need to buy based off Realoem from my question in the post.

Make absolutely sure that you are buying the parts you need.

Manual Sport Seats are different from Powered Sport Seats.

Unfortunately frame cracks are usually hidden. I just disassembled a seat I thought was good. Turned out both upper and lower frames were welded. And it wasn't done well as one repair was at the Hinge pin. Good luck
