Are these aftermarket sway bars?
 

so I'm still trying to discover all the cool things that came with my parts car. I know it has a strut tower bar, but I'm not sure if these are expensive sway bars?https://cimg5.ibsrv.net/gimg/www.rx7...b790867d56.jpghttps://cimg6.ibsrv.net/gimg/www.rx7...87ad023e5b.jpg

Looks stock to me, though to find out for sure your best bet would be to measure them.

look stock to me as well.

if the bushings are all rubber instead of polurethane then yes, stock, but since your pictures look like they're underwater i can't tell.

Kinda shiny for old parts where someone rubbed the dirt off. Find out if they're hollow. Most factory bars are and to make a swap easier, many aftermarket bar makers just made them solid but the same diameter to get the extra stiffness. Compare them to a factory bar to see if they are heavier.

Holy blurry pictures batman! Fom what I can make out they look stock, but at this point that's just a guess.

the stock bar is not hollow, nor is it light.

Even it isn't is stock, can I install it on my gxl and will be it an upgrade? https://cimg3.ibsrv.net/gimg/www.rx7...ed3ad790dc.jpg
