alignment questions after m3 suspension parts upgrade

after adding the m3 rear guide rod and rear upper link to replace the factory pieces on the rear suspension on a 335i, do you need to have an alignment done? Do any of these replacement pieces have alignment bolts associated with them?

thanks

PM Mr. 5 ............. you might want to have the 4 wheel alignment atleast checked just to be sure.

Alignment is definitely needed.

I have all the M3 parts on my car and they did the full alignment with corner balancing. The shop said those parts you mentioned above pushed the rear wheels out a little bit further than stock and it changed the alignment settings.

I don't know the answer on your alignment bolt question, but just PM Harold at HP Autowerks.

There has been a fair bit of discussion in the past regarding alignment specs on 335s with M3 suspension bits. But I would really appreciate an update from knowledgeable sorts on this subject. As a reference, here are the specs from my recent alignment:

lf rf lr rr
camber -.7 -.7 -1.8 -1.8
caster 7.4 7.4
toe .12 .1 .15 .15
thrust angle 0.0
