would the same stabilizer bar that runs across my engine bay work in the rear as well..?

If you're talking about the FSTB (front strut bar) than No.

i guess thats what i meant... so where can i get a REAR Strut bar?

Active Tuning makes a VERY nice RSTB............I have one for my NX and I was/am very impressed with the workmanship and quality of the product.

Plus, it's billet aluminum and stiff as hell.

where can you get those? i went to their site and they don't have a section for the nx. unless i am blind....possible

Back in the day, you would get all kinds of search noob responses...its Friday, why not ;)
