does a front and rear upper strut bar do anything

cuz i put them on and i dont reely feel anything but the front one gets in the way alot when im working or cleanin my engine

 

the rear does more than the front, but they don't make a world of difference....just a bit less flex between the shock tower points, but most effective when the rest of the chassis and suspension has been addressed.

so i guess to answer your question

yes, they do something
but
no, you won't "feel" much of anything

 

By bracing the top of the shock towers you increase vehicle stability and overall predictability.
