to be honest, i've seen some "big name" bars flex more than the no name bars.

if u put both arms on the strut bar like u're doing a push-up, and the bar flexes, its junk. for the longest time i had a "matrix" bar in my first integra. it was just as stiff as the other bars out there.

if u're about looking OEM AND having the OEM designed strut bars (stiff) then thats even better.
