it would all depend on what you are trimming off of the lower arm, if you were actually cutting away the main structure of the arm, yes you ought to reinforce it, unless you are going to encompass the bag bracket into the structural integrity of the arm where you removed the original material. but if your just removing something like the shock mount, no, it will be alright.
basically if you think it's weak, reinforce it, if not, ride out & dragit!
