I'm looking to get in on the group buy of benen bars and was wondering if anybody here has used them.

More specifically, the Strong bar and the cross member bar. Do they make a difference and if so how much? I can't seem to find any info...

 

I have the BENEN strongbar for my GSR, and what is basically does is allow you to safely remove the rear bumper support to save a good 30 lbs. It does stiffen the chassis a little to because I noticed the reeking and sqeaking were gone when I go through a speedbump, etc...

Here's the link to my webpage to some pics:
