Congrats! Nice list so far.
I would recommend rear sway bar. Stock is 24mm front and 16mm rear. Bring up the rear anywhere between 19-22mm and your ride will improve dramatically. Overall, the ride will feel more balanced and take away some swaying around turns. It doesn't take all the swaying but it helps towards it.
Thanks man I'll definitely do that. I don't know much about sway bars so are endlinks a must or just recommended?
