Though, I'd like to point out that in an integra, you will get much more significant handling upgrades from a rear lower tie bar and a rear sway bar than an upper tower bar, mainly cause the placement of the rear UCAs is so low.

Upper tie bars do help, but it cuts badly into your cargo room and, dammit, don't buy cheap ebay shit when it comes to your suspension. If you wanna get a cheap ebay muffler or intake, fine, but your life and the lives of other depend on your suspension handling properly...
