    I'll probably be banned for saying it but Topaz is so much better than LSB. Car looks awesome.

      Thanks! I feel like Topaz is a super polarizing color.

      Sometimes I hate it (usually in low light), but other times it looks pretty great (like yesterday).

        Topaz is my favorite e46 factory blue.

            Today, I managed to turn a 10 min job into a 2 hour one.
            Car was squeaking a bit when turning the engine off, so I decided it was time to swap the belt tensioner. Unfortunately, one of the bolts snapped when I went to remove it:

            Ignore the dirtiness. Looked mostly like old oil and grime that hadn't seen the light of day in decades. Cleaned up relatively easily.

            Anyway, there was still a bit of the bolt protruding past the oil filter housing, so I decided to try extracting with some vise grips. Sprayed some penetrating fluid then ground a flat into the threads so that there would be something to grab onto (and to get a bit of heat in the bolt).

            Fortunately, it worked!

            Replaced it with a hardware store bolt for now, but factory part is on order. Also ordered all the surrounding bolts just in case.

            Glad it was a easy fix, but also annoying to deal with. At least the belt isn't squeaking anymore!

              Finish is Cerakote Arctic Black P-202. Supposedly designed to help dissipate heat. https://www.cerakote.com/shop/cerako...lack-oven-cure

              Now just need to find some time to rebuild them and get them on the car.
              ​LOVE the Cerakote finish!! I regret not doing Cerakote on my 996 calipers.

              The car looks really fantastic with these, Heinz. Love the subtle tone rather a punch-me-in-the-face color. It compliments Topaz really nicely.

              And I'm 100% sure my wife would be happier if I left my car alone, lol

              Your car looks stellar. If any car on this forum makes me second guess my sanity, it's yours.

                Thanks man! I do think the black was the right choice. I'm not very interesting when it comes to colors (in case that wasn't obvious), so I'm really liking the look


                Also, found some time to edit pics. Here's another dump:

                      Sounds like a good way to send a car rolling down a driveway. 🫠

                        hahah!!!!! That might be a hard one to explain to my insurance company on how I lost another M3 down the driveway. "So you see, it happened differently than last time. This time I was trying to install this structure rear brace that stiffens the chassis 30%, so I built this ramp...."

                            Speaking of the rear wall, I've had an idea for losing a decent chunk of weight for a while that was infeasible until I finished up that install.

                            The rear seat backs are pretty heavy due to the metal frames in them and I figured it wouldn't be too hard to make them lighter. However, without the wall, there would be very little to attach the frameless seats to, so I hadn't given this project a shot until now.

                            I picked up a spare set of seat backs to practice on and took them apart. Haven't gotten past that, but figured I'd document it for when I do this on my actual seats.

                            Started with the smaller one and removed the top plastic trim by pulling straight out:

                            Click image for larger version  Name:	20230905_201012.jpg Views:	2 Size:	212.5 KB ID:	232409

                            Then went around and pried this retainer off of the metal frame. It's stitched onto the leather, so once it's free, the leather is too:

                            Click image for larger version  Name:	20230905_201139.jpg Views:	2 Size:	148.1 KB ID:	232410

                            With that all pried up, the leather and foam are almost free. There's one T50 torx bolt at the bottom that needs to come out and then you can separate them:

                            Leather is held onto the foam with some hog rings:

                            Click image for larger version  Name:	20230905_203417.jpg Views:	2 Size:	102.4 KB ID:	232414

                            And that grey carpet material is just glued onto the metal frame. Pretty easy to pull apart:

                            Disassembly of the larger seat back is mostly the same. First the plastic trim comes off, then the leather is pried away from the metal frame and finally the leather is detached from the foam by removing the hog rings:

                            Armrest assembly is held in with one T30 bolt:

                            Couple plastic trim pieces to remove, couple leather flaps to undo and one long plastic "clip" to separate and then the leather can come off:

                            And once again, that grey stuff is just glued on and easily removed:

                            Click image for larger version  Name:	20230905_211159.jpg Views:	2 Size:	178.3 KB ID:	232426

                            With everything apart, I weighed all the individual pieces. Here are the results:

                            Small Leather 1.3 lbs
                            Large Leather 2.2 lbs
                            Armrest Leather 0.9 lbs
                            Small Foam 1.8 lbs
                            Large Foam 2.3 lbs
                            Armrest Foam 1.2 lbs
                            Small Metal Frame 7.9 lbs
                            Large Metal Frame 16.3 lbs
                            Armrest Metal Frame 1.9 lbs

                            Now comes the question of what I want to remove. I think I've decided that I'm going to keep the leather, foam and grey carpet pieces. Previous experience with folding the seats down tells me that the foam is doing a ton of work to keep cabin noise down, so if I replace it with some lighter stuff, I'll likely need to add some sound deadening in. I doubt that I can get some other foam and sound deadening to weigh less than 4 lbs, so I'll just keep the OEM stuff. Plus, that means the cushions will be stuffed with the factory preformed foam and not something I hacked together in the garage. Should keep them looking exactly the same as before.

                            Next question is how to mount the seats back in the car with the frame gone. This is where those grey bits come in. I plan to sew some heavy duty velcro strips along the top of them and then glue the carpet + velcro assembly to the foam. Will probably also sew some velcro strips onto the sides of the leather to be able to velcro both seat backs together.

                            Last thing to consider is the armrest. This will likely need to be stuffed with some other foam. I'll try to separate the armrest foam from the armrest frame, but it didn't seem trivial. No big deal if I have to buy something to stuff it with though, as it's just a rectangular prism.

                            Final weight savings to be seen, but should be around 26 lbs. Not bad!



                            Also, felt irresponsible to not give a big disclaimer about this work. I understand that part of the reason the metal frames are so beefy is to prevent stuff that's in the trunk from entering the cabin in the event of a crash. I feel okay removing this safety measure for three reasons:
                            1. This car is far from a daily now. The most I put in the trunk is some tools that I bring to the track. This trunk will likely never see big, heavy, bulky items again. If it does (e.g. a spare for a roadtrip), it's getting ratchet tied down.
                            2. The slon wall will help. While the carbon is more brittle in the direction that things would hit it from, it should still absorb some of the kinetic energy of the objects that hit it. With that said, I do understand that the wall stops helping if something hits it and makes a hole through which other objects fly through.
                            3. I'm already thinking of building a crash/hard braking guard to go in the trunk. Will likely bolt/clip in underneath the parcel shelf and then clip into those cargo net brackets on the chassis rails. This could be a net or a piece of plywood or some sheet metal, I don't know yet. I want to add this because I really don't want to crack that rear wall. It's not inconceivable that a small, pointy object placed in the trunk could fly towards the wall under hard barking and crack the carbon, which would reaaally suck.

                              Yeah, I actually chatted with SLON about this notion 3 years ago— if you are using the back seat as a seat, this is not a good idea. If you have heavy items in the trunk, not good in a crash.

                                Interesting idea.

                                I've been passively trying to figure out a rear seat delete option that doesn't look like crap. I never use the rear seats and if I had the Slon wall, I'd pull them. But I don't like an unfinished look in a street car, so something would have to go in its place that isn't a piece of plywood covered in carpet.
