If you go over to my posts you will see how I put my street edge in but I bought new strut tower bearings and kept the orig susp in tact. Basically three bolts at the top and two on the bottom. Real easy. You will need a pass thru wrench kit from crappy tire tho to tighten the bolts on the top of the strut. But pretty straight forward. But it looks like you setup has stock style springs ( top portion anyhow) so additional parts might be needed. The rears were a bit awkward as I forgot to release the handbrake so do that when you have it up, I wouldn't rely to heavily on the BMW emerg jack tho to hold the weight for long!!. You will need both front wheels off the ground at the same time tho'
Can't think of much more
