Do you want stock or aftermarket?Will entertain any except whiteline
My Personal favorite is eibach, they offer a very nice sway bar setup with loads of adjustability 3 way, and it's got a tubular design for weight savings, 29mm thick if im not mistaken! Handling over stock is night and day, have used in all my cars up till now. Pairs nicely with their springs too.Corrected title, aftermarket
