Hubcentric spacers

I bought a new set of wheels for my e30 which required some hub centric spacers. A local machine shop did the work and made me a set of 1/4" ones all around, problem is I only asked for the fronts so I had no clue they made rears untill I went to put winter wheels on. For some reason, the rear end seems to be narrower than the front, and I need to space the rear wheels out yet again. How large of a spacer is ok untill it get's dangerous? I plan on adding about 9/16th's to the spacers and welding the two plates together. I have all the facilities and help to make this work safely, so the quality is not a problem.

Is a 13/16ths spacer too large to be safe? My little brother rides in this car so I can't take any chances.

Those are perfectly safe, given you have strong studs/bolts.

I think its its a wise idea welding to together. Its better to just get a wider set made.

Everything needs to be perfectly flat and balanced, or u'll get viberations.

Yea of course I'll run a bead along the outer edge with the tig. I just don't want to go through the bs of having another set made to simply space the wheel out even more. The shady shop that had them made was supposed to give me a quote for all four and I was going to have the rears made at a later date with a much wider spacer, but they screwed up and made 4 the same width so now they're giving me the material to work with.

What bolts should I look at using, I assume I can just buy generic length bolts at an autoparts store and cut them to length myself?

No, don't cheap out on lugs. Stacking spacers shouldn't be done either. The studs need to be grade 10.9.

They'll be welded together by a man who's welded aluminum for Aircanada, should be plenty sturdy. A proper weld running alone the entire outer edge will last longer than many parts in the drivetrain.

haha, I did mean generic WHEEL bolts, I'm not that incompotent. I'm going to order a set of H&R wheel spacer bolts from turner. Pretty sure if their's won't hold up most won't either. Any other advice oh ever so great e30 god?

Yeah, I'm sure your "air canada" welder can weld the aluminum spacers, without warping them, ensuring perfect balance.

You clearly know nothing about working with metal, ever heard of a lathe? You know, that thing that spins really fast and you can shave metal off in circles, works great for making things true. Don't make smart-ass remarks when you know shit all.
