Back in my Maxima days everyone said they are mostly for looks. The front bars make a huge difference, but the rears...not so much.

Upgraded rear anti-sway bars may be something to look at though.

if you pair the rear strut bar with

sway bars and coilovers your car will feel like it is on rails when you make fast turns.... trust me i have all of those suspection mod's and my ride feels like that.....

but a rear strut bar is only good if you make fast turns... driving regular it won't make a difference it will be for show under 50 mph turns

Basically the rear seat is a huge 50lb strut bar right now, it's pretty heavy for a seat. Putting on another one is essentially adding weight. Now if you were to take the back seat out and replace it with a CF plate, then a strut bar would def be a good idea.

I don't get it... Explain to me how the rear seat acts anything like a strut bar... Do you know how a strut bar is mounted?

well ive looked around for strut bars and all i find are those ebay 30 dollar rear strut bars. my old car had front and rear strut bars that were $500 and honestly since ive been through both name brand and ebay i dont think there is a difference. both are metal and stay solid. its not like the cheaper one will bend. i think i will buy that ebay one and see if its useful.

im also going to go ahead and order the pss9's, unless anyone has any other reccomendation for coilovers.

IMO a strut bar only helps on hatchbacks.
Coupes have lots of steel to keep it from flexing.
Hatchbacks don't have the necessary steel due to the hatch.
Unless you are SCCA racing or something like that.
save your money.

The rear seat definitely acts as a stress member for the chassis if you have fold down rear seats. The locking mechanism/latch thingy that connects the seat and releases it so it can fold down (I don't know what the part is actually called) has gotten a little loose in my car, now every time I turn or hit a bump it creaks like crazy, it's so annoying. I have to tighten it up soon before I go crazy. But yeah it's definitely a stress member of the chassis.

If you have the folding rear seats it should make a noticeable difference and should probably improve ride quality as well. I'd probably go with sway bars first then a rear strut bar. If you do that it'll be hard/impossible to find another car that handles better.

sorry. by no means is the seat a structural component of the car. it is not a stress member.
in your case, it simply wobbles around. its not that your structural integrity is compromised.
