Super wobble in curves, help!!!

[Astromic]

Hey guys,
my '74 super beetle wobbles again after front alignment and tyre rotating(balancing), but the strange thing now is that it's not wobble when driving in straight road, but it wobbles like a mad dancer when taking a slight curve at mid-speed(3rd gear),,,
is there is any way i could solve this, because it's strange problem because all sb wobble at straight road, but mine wobble only in curves so i don't want to change or do anything more before asking u here...
thnx in advance...

Michael
