can you enlighten me on m3 calipers? are you going 5-lug?

Yup! I am in the middle of an e30 M3 5-lug conversion so I'll be running the stock M3 brakes all around as it is required by the swap. I'm also changing to an e32 750il brake master cylinder (slightly larger bore than the OEM M3, but with the correct threads for non-m e30 brake line fittings) to compensate for the bigger calipers.

nice! i'm a bit dense - the weds you posted were 5-lug and I didn't put 2 and 2 together.

Picked up a new core support from Umansky to replace the bent replacement (also I cut that to pieces getting the new frame rail section out haha), these things are pricey but knowing it's straight is worth the premium. I'm hoping to finish fitting all the patch parts and start welding things back together this weekend! My overall goal is to have the body repair done by the end of April.

Got some good work done with the great weather this weekend!
I was able to massage the inner bumper shock support back into shape. It's not pretty but you can't see it once everything is back together.
Finished fitting the new bumper mount and got everything mocked up. Everything seems to be lining up really well. Next step is to lightly tack it all together and check the panel fitment. Hoping to have that done this week so I can weld everything up for good!
Got the differential mount reinforcement plates welded in:
The three exhaust heat shields were looking pretty gross so I cleaned them up with a wire wheel and sprayed them with some high-temp silver paint:
Opened up the medium case 4.10 LSD that I'll be using. Its got a bit of sludge inside from sitting around for a while, but the internals seem to be in great shape. Hopefully all it needs is some new fluid and it's good to go.

Here is an example of hairline cracks forming, from a build thread on r3vlimited (JGood's m60 swapped e30). I recall seeing it once or twice more in other random build threads too, but it's not very common.
I will be running subframe riser bushings that require spacers to lower the diff back to it's original location. I wanted to add the reinforcements to compensate for the increased stress the mounts will see (less contact area, increased distance between the diff and subframe). Its definitely overkill for a stock m42, but with more power planned in the future I figured it was good to do while I was in there for added peace of mind.

That example was overtorqued, but that is understandable since there isnt any way to get an accurate torque on those with te subframe installed anyhow
Thanks for the info
Hadn't thought of that but it's definitely a possibility, I read a little more of that thread and he did mention that he had the diff bolts come loose at some point so that could have also contributed. Either way, got some welding practice and it doesn't hurt anything haha

To the picnic or bust!
I couldn't help myself on this one though, its a fairly quick job that should make a huge difference

Made some great progress the last two days after work.
In the middle of installing the UUC rear sway bar and reinforcements, had to do a lot of adjustment to get the brackets to sit just right but I finally got them where I wanted. Drilling holes in the trunk floor is a bummer, but it seems like the only/best way to prevent issues.
I also started started welding the front end together. The metal is very thin so it's going to take about a million tack welds to get it done, but it's moving along quickly which is awesome. On the bumper mount, I missed a cut by about 1/8", so I will have to make a filler piece to close the gap, but that's no big deal.
With the parts securely tacked in place, I fit the core support and mocked up the front end to check panel gaps/fitment before I weld everything together for good. Looks like I'll be able to get decent gaps all around which is great news. Everything is just loosely set in place in these pictures so things are a little off, but there is a good amount of adjustment in everything.
Definitely a huge motivator seeing it starting to come together!

visual progress like this is a huge win and motivation for sure. It even looks like a real car now! What could possibly go wrong between now and the E30 picnic

Thanks guys! It was kind of a bummer taking it back apart haha, but I'm hoping I'll be assembling it for good in the very near future.

Well, there are somewhere in the neighborhood of a million things to do before it's roadworthy, but I think I have a good handle on what still needs to be done which is half the battle. I'll be pushing hard all the way to the 20th!

Sweet jesus, I didn't realize you cut the end of the frame horn off. Bold.
Fit up is looking good!
You're repairing something I wouldn't even feel comfortable diving into lol
