some generic ones are actually stiff. if you can, put some weight on the middle of the bar thats installed in another car to see if it flexes. i've seen DC's flex A LOT, and a slew of generic bars. i got my front strut bar from a friend for free, and its pretty damned stiff. i'm also running a factor GSR strut bar in conjunction with the other strut bar. one mounts on the shock bolts, and the other through the factory mounting position. keep in mind though, some grinding and modificatoins will need to be done to the GSR bar to keep it from hitting the shock tops and the throttle position sensor.
