Frame rails

Has anyone had any of these uprated frame rail covers/bracing fitted.  Been looking at them at Performance 5’s website and some Jass performance ones on the Autolink site.  They look like a good idea both for protection and performance.  Any one got any opinions on them?

Cheers my dears.  

I have them fitted. Noticeable stiffens the chassis up from flexing. My chassis rails were fine, before too.

Me too.

+1 for stiffness, becomes ever-more important the older I get…
