In between all this I ran into an interesting problem with the wheels Id bought off another e30 enthusiast back in May..
He had 4 of these, BMW BBS Style 5, all refinished with new rubber:
Classic e30 rims... I thought "Great! Im good to go!"
So I paid cash and set them aside while I worked on the sanding of the car for the next 5 months...
When I finally put them on I realized I wasnt as
good to go as I had thought..
Did you spot the trouble spot??
Seems the offset was different.. If you didn't know it let me tell you BMW used several different offsets for the same wheel style.. These were ET41: 41mm offset from center. For most e30's with this wheel style the offset is ET30 = 30mm..
Live and learn right?
The solution?
oh, and Ebay.
To make up for the 11mm difference I purchased 12mm spacers (there are no 11mm spacers..)
These have the center bore at 57.1mm which is standard e30 diamater for the hub:
The outer flange is also 57.1mm to accept a standard BMW/BBS wheel..
They install flush to the face of the wheel: You should put a light coating of copper grease to prevent corrosion and binding between the spacer and the wheel and the hub. Im not as I will be disassembling these a few more times before Im done...
Like so.. You can also see the standard lug vs. the longer one needed as supplied with the spacer...
Once mounted they corrected the offset and the front wheels now sit where they "should"..
The rear wheel clearance is fine and actually look alright but I may yet put spacers on them as well..
Here is a link (German) for all BMW wheel styles and offsets..

Now I can go to bed a little less dumb than when I woke up this morning!
