I got lucky and got a chopped up early production syncro-design mid pipe. I didn't know the early production units were just mild steel, however it made it a lot easier (cheaper) to get back to a usable state.


all welded up

I've been ordering different consumables and even ordered another angle grinder (air) just because prep has been so excruciating in the las vegas 100°F+ weather. I'm weird and didnt want to run the garagistic RTA reinforcements again so I ordered the SRS kit and Stim-tech rear shock reinforcement. Turns out the SRS kit won't work with how my trailing arms were shortened to run the MRT DTM kit so i'll be running the garagistic boomerang afterall.






I actually ran out of 75/25 gas for my mig, so I had to drive 40min away to go swap a bottle out. There are closer places but the one 40 min away charges like 55% less (kind of insane and totally worth it). I also bought myself new tig torch (furick) gas lens kit to start practicing again. Clearly I have a lot of welding projects in my future, and I would love for everything to have wayyy nicer welds this time around.
So the problem with running 318ti rear TA/hubs is that the hubs are +20mm more than stock e30 hubs and +17.5mm more than z4 hubs on e30 TA's. That means if I wanted to keep all 4x e46 325i rear calipers (and functioning parking brake) i'd have to upgrade to a rear rotor that has the same 294mm rotor but with the hat to match the increased hub offset. Luckily this was easy to find by just searching for "318ti rear brake upgrade" and all the info was on SRS-concepts site. So I ordered up some zimmerman rotors from FCP. I could not find if my caliper adapters will be the same, but I can always add a couple washers and longer bolts if I need to order new adapters after I mock it up.

e39 touring update:
turns out 525/530i tie rod assy is the same thread/pitch as e30/36/46 which means i can add a little cheap angle to it since I have some old tie-rod spacers for the e30.

I also sourced a 530i 3.46 188k open differential out in socal that already has the MT input shaft flange swapped out on it. (e39's are annoying like that, AT/MT have different length input shaft flanges on the diff and 2 different sized drive shafts of course) So it's kind of a pain trying to find this combo in a face-lift e39 right out of the box basically. The plan is, he'll actually be bringing it out to vegas in 2 weeks, and I'll just pick it from whatever hotel he's staying at on the strip. I already bought the weld-in plates for the diff, and another pair of SLG axle spacers. I'm sorry I can't help myself, I have to slide it.

What's brilliant about all this is I'll be able to swap it back if I hate it or am planning a longer road trip with it but I do want to try and have some fun with this thing while the e30 is down, so this is kind of a high priority suddenly and then I'll start actually working on the e30 slowly again.
