92 civic si over 80mph car shakes horribly would it be balancing or do i need an alignment i know i should have searched

 

Wheel balance or flatspotted tires (if it sat for a long time or you locked the brakes without ABS and slid for an extended period of time). Either way, they're both balance related.

Might want to check your lug nuts just for sanity's sake.

 

they are not flatspotted they are relativly new
