boxed trailing arms

Another option that I had considered is using an E9 control arm. They are much stronger, but also a bit heavier. They are also a little longer so result in a few degrees of negative camber without having to use a fixed or adjustable camber plate.

why not E21?

bmw thought it was necessary for going from 100 to 130bhp, so I'd say yes. $100 a side? Realoem lists over 500 and I didn't even think they were available.

I think Winston is refering to welding on the front control arms- not the semi trailing arms.

Yes I was talking about fronts. I'll be running e21 rears or maybe e30 but boxed either way. Fronts I just don't see the point unless I had a full blown track only car, lowered, and was really worried about it. To me there's no "coolness" factor in boxing your front arms. - IMO
