No...technically you are not changing any alignment angles unless you are ordering the Caster offset versions of the bushings...most people order the 0 offset ones.
Although, if you haven't had an alignment in a couple years, it wouldn't be a bad idea...just in general.

Thanks, i assumed these affect alignment because of the eccentric holes. Why not use standard bolt holes then?

I can only guess that the slotted holes allow for fitment on a wider variety of vehicles. The GSF/RCF bushings fit 3IS, 2IS, ISF, GS, RC, and probably more vehicles.
I'm sure if you force it in one direction or the other it could effect the alignment, but letting it sit naturally seems to be the easiest thing.
