Parcel shelf - functional rear seat delete
Hey 1addicts. In thinking about weight reduction but not wanting to lose functionality of the 1er, I've started brainstorming on the possibility of a rear parcel shelf. No one ever sits in the back seat.
Would be similar to Cakeaters seat delete panel for those that remember that, but need to figure out how to make one that is load bearing and could receive and keep the functional car seat ISOFIX mounts. cakeater https://www.1addicts.com/forums/showthread.php?t=819595 Rule is 55lbs for seat delete, so even if I could end up 20-30 lbs down with the custom shelf installed, it would be worth it. Plywood comes to mind since that's what was used in the DIY, but thin and light is not weight bearing and thick is heavy, so considering other materials. Obviously carpet covered, dynamat, and thinly padded at the end. If anyone has any thoughts, I'd love to hear them!

Never had back seat out of my 135i so do not know what kind of attachment points exist which is the big influencer on design for me. Replaced rear seat in my Crew Cab (Colorado) with a shelf for tools and fasteners (remodeling). Includes 75# saw and cordless tools.
You can use thin (1/4" or 1/2") plywood and get stiffness if you have enough support (use aluminum). Just keep in mind what the weight of your track wheels or suitcases or groceries when designing. Also, do not be afraid to make something then replace it with an improved design because you learned something (prototyping). Good Luck. |

First light and strong materials, a sandwiched aluminum honeycomb panel comes to mind. A little more difficult to maybe attach into (if you wanted to a hinged design like the P-car, might have to add some support or attachment pieces), but if you know someone in a construction or building trade they might be able to get you a sheet for cheap/free.

Don't care about it being hinged. That was just a nice build that guy did. Just needs to be removable so I can get to the fuel pump.

Looks like a 2'x4' sheet of perforated 1/16" aluminum sheet can be had for around $90. 90degree crease and sandwich that between two pieces of thin ply and it might be adequately strong if then supported by bracing to the chassis. The sheet weighs ~4lbs too.
Now to see if I can source the pressure clips that hold the seat down to the chassis. I'd be satisfied with high strength Velcro in the back by the trunk, but want the front of the shelf held by the clips like stock.

You lost me a little to be honest. I'm not following your aluminum sheet sandwich detail with a 90* crease somewhere? I don't think the aluminum sheet is really going to add much flexural rigidity in a sandwich of two thin plywood sheets, especially in the long direction.
Or is the Aluminum sheet going to go in the backrest area, and the 90* degree crease is at the transition from vertical backrest to horizontal seat area? So the sandwich is the connection detail for the aluminum vertical to plywood horizontal? |

Need to either get measurements from someone or this will have to wait until my car gets back from the shop.

I'm interested in seeing how it turns out. I never use my backseat, and plan to do a delete at some point as well.
