nothings wrong with em I have one. a strut bar is better than no strut bar. When you look at the way the chassis is shaped like a tub you'll want something there. As long as you install the bar right should be a problem. Man sure you tighten it, if you tighten it, it'll make it more rigid. You should hear a thunk when you tap on it. You should be able to lift the car up and down with it without it bending also.

hehe I got 2 strut bars though :P

heh if you really want a more rigid chassis look into spot welding or a roll cage hehe.
