Does a front strut bar increase understeer? Why?
 

I got one recently, and think I lost some coner entry willingness. I made a few other changes recently too, so my frame of reference is weak. Has anyone else experienced this?

Unless you had a serious amount of strut tower flex it should not effect it much if at all.

Probably your other suspension mods had more to do with the change in handling.

deleted. I thought you were talking about front sway bar, not strut bar.
