Also, your measurements are wrong. Should be 114.3mm shouldn't it?

Correct, should be 114.3 - must have hit the wrong key in UG. I'm not really too afraid of deforming the aluminum - it is under compression after all. What are you torquing your lug nuts to anyway? I've some some aluminum lugs torqued to 70 ft-lbs right now (per Enkei's suggestion). My concern with steel is corrosion due to different mating materials.

Plans are changed a little - I'm going to try to get them to make a spacer + hug ring for the rear (10mm spacer + 59.6 to 76 mm hub ring for the Enkei's). I got a different idea for the front now... Ebay sells "hubcentric" rings in a number of sizes from 5-25 mm for $60-$120. I'm curious what the shop comes back with price wise.

Either way, the original plan was for something thin so if anyone is still interested I can correct the drawing above and still inquire.

FWIW, what does having Enkei's have to do with not necessitating hub rings?

I usually torque my lug nuts to 80 ft-lbs (bad experience with me throwing them on 81). I think steel will be fine and won't react with anything as the disks themselves are steel. Aluminum might be fine if you're not worried about deformation--though they themselves may or may not react with the metal given the right catalyst (salt water, etc).

My big reason for going with aluminum is I'm more familiar with those alloys. There's a billion steel alloys out there and I'm not really sure which ones would fit this application.

Re-torqued lug nuts to 75 ft-lbs today

I also found a different solution for the front today - camber bolts. Used some camber bolts to pull the tire away from the strut at the bottom, then used the strut mount to dial the negative camber back in. Worked perfectly and cheaper than spacers.

I'm likely going to pose my second idea to the machine shop sometime this upcoming Wednesday. I'm going to try to have a 10-15mm hub centric spacer, with hub feature made (so I can use my existing hub rings). These will not have studs in them so they will require longer studs (2.5" ARP's should be fine).
