The front sleeves were almost exactly the same diameter as e34 strut housings, so they were going to work perfectly. Unfortunately, I had a set of e28 housings laying around an decided to use them so I could start on the coilovers with the e34 still on the ground. Unbeknownst to me, e28 housings are .1" smaller in diameter than e34 housings so the sleeves didn't fit snug.

I ended up having some perch rings made with a step machined into them to center the sleeves on the housing. This would probably carry over to the e30 if you wanted to make your own coilovers for one, you'd have to make something to center these sleeves on the housings.
All welded up, thanks to Lorin and ready to go on the car (for the first time)-

My plan was initially to use Bilsteins all around with full length housings. I thought that I'd be able to use 6" ~500lb springs all around, weld the rings pretty far down and squeak by with just enough travel to ride as low as I wanted to. Unfortunately this didn't work out-
This is with 2.5" of travel. Not low enough and probably not enough travel-

And bottomed out perch to Bilstein gland nut.. Still not low enough-

That obviously wouldn't work. So I decided to go ahead and buy some short Corrado g60 Koni yellows. These are 4" shorter than factory stuff and would allow me to shorten the housings. I decided to take 2.5" out of the housings, if you look at the picture above I had a lot of room from welding the rings so far down before so I was able to not mess with the area where the perch was welded previously, take 2.5" out from the housings above the perch and just cut down the sleeves. Thanks to Steve @ Apexdesigns for the work on the housings! I got everything back together and it was a lot closer to what I was looking for (got some new wheels too)-

This worked out pretty well but I was still a little low on travel because of the height of the front upper perches that I had. I found some flat perches for sale locally and they worked perfectly, you can see the amount of travel it bought me comparing the two-

New perches and short housings, with 3" of travel still and some room on the adjusters (tires were hitting tops of inner fenders)-

15's btw^
So, suspension finished for now. On to cosmetics..
