So I put a supercharger (Stillen V3) into my 2007 350z and the stock strut bar was among several items that was removed. That being said, all cars, even more so for those that have over stock HP, benefit from a strut bar. I asked Stillen about their modified strut bar, and they said it was for 2003-2006, not 2007.

Do any vendors make strut bars for 2007 that take into account forced induction manifolds?

 

I know with the Motordyne plenum spacers, they supply washers to provide extra clearance for the strut brace to the now taller plenum. I'm not sure if its quite so simple with the Stillen HR Supercharger...
