Hollow or solid all that really matters is the stiffness. I've used hotchkis for about 2 years and I like them. I would get aftermarket endlinks though.

 

Hollow bar thats welded.. versus sold one piece bar...

I'm just saying if you have an 05+ Sport G35 (6MT or Factory Sport Package) you're not benefiting anything by changing your front sway to any of the hollow sway bars.


They did tests with the sways bolted at the stiffest setting

 

^ No difference if (on the hollow bar) you set it on the med hole. But everything does get noticeably stiffer/flatter if you set the end links in the hard hole.
