if the front is fine with 10mm of clearance to the strut then I will run it without the spacer in the front. in this case the outside of the front wheel is equal to the stock location. Then I would run the 5mm spacer in the rear. this would give equivalent track width front to back that you suggest. If I get more oversteer than can be adjusted with tire pressures I can always change to a 10 mm spacer in back, but I dont think it will be a problem.

Iknow the e46 had more understeer to begin with , but I ran rear wheels all around on mye46 with 265, which gives a wider relative front track over stock by quite a bit. it was very nuetral on the track.
