Sway Bars

[MarkD168]

My 2006 Miata waddles quite a bit when driven over manhole covers and shallow potholes. Front sway bar looks to be a Racing Beat model with stiffness adjustment in the outermost holes. End links are stock. Shocks are stock Bilsteins and springs are Eibach Pro Kit 5536.140. Rear sway bar appears to be stock. Other than the waddling, I’m happy with how it handles—mainly use it on twisty roads; no track, hard cornering, etc. Any suggestions for reducing the waddling?
Thanks

Added stiffness somewhere would do it. That could be rear sway bar, higher rate springs, some adjustable KONI shocks with the springs you already have, even a stiffer wheel/tire setup (tires have spring rate and wider wheel for same tire size makes a bit difference in that effective spring rate.).
