I’m looking to get a rear sway bar for my 2013 vw Passat, its on bags atm, the bags are pretty soft and if I run them pretty low on hard corner I rub holing a sway bar will help, I think I’ve pretty much narrowed it to the neuspeed 28mm or the 25, is the 28 overkill? Do I need anything else to go with it? Any recommendations?
