<my pilot rear lower and upper bars are pretty stiff...they don't move whatsoever...my front is custom, but still... all they really do is stiffen the chassis....the handling still feels the same...just maybe not as "gooey". Also, if you have a stiffer suspension, strut bars have more of an effect because stiffer springs will cause the chassis to flex more....IMO, don't spend more than like 60 bucks on a bar.>

Exactly what they do, stiffen the chassis! You go from they don't make any difference to all of the above. If you took out...the handling still feels the same....it would be a awesome statement. You say the bars stiffen the chassis and the handling is not as gooey. You contradict what you are trying to say. You even say they are even more effective with stiffer springs. It's like you tell the guy to buy them in one sentence and not to in the other. What gives! I even agree with you that $60 is enough for a front bar. Maybe even the back. Just as long as it isn't the Pilot rear upper. I'm not bashing any of the other Pilot bars, just the rear upper strut tower brace. It is the worst designed bar i have ever seen. Others on this board have also agreed with me on that in the past. Maybe that is why you haven't noticed much of a difference with your bars.

Point is, you will notice a difference unless you drive like a grandmother.
