I've been running on the stiffest setting and so far the frame mount bushings it came with are holding up fine.

It's been a while since I checked so I may be wrong, but that sounds about the same as the ZLE rear bar, which is hollow and lighter. I got one for about $100 on ebay. With the MCS coilovers I like the middle setting best overall, although I need to do some testing to see if soft is actually faster for autox. It's definitely too soft on track. I'm also running the Hotchkis ft bar on medium.
I'm dialing in damper settings for the bumpy venue we use, I can't believe how much time it's worth...
