From what I've seen when I was putting in exhaust I believe these numbers are correct. with 23 front and 16 toothpick in the back. I Just found a guy with a stock 2013 rear sti bar with bushings almost new that I can get for $50. (either 19 or 20mm?) so I think I May pick that up and run that for a bit till I decide to switch front and rear out. to a 26mm front and 22(23)mm rear whiteline like you were saying. that sounds like the setup I want down the road a bit but we'll try this for now (for 50 bones can I go wrong?). im already sitting on hnr lowering springs and 245/40/18s so it should be nice I think.
Thanks for the suggestions! and ill see how this comes out. ill probably want even more though after I get a taste and will be changing it right after haha.
ps. would I need a realignment after just a rsb install?
