I have a 99 ex and I thought about putting sway bars along with strut bars on her but do i need them?

It will stiffen your car up some. It wont hurt it but from my experience you wont notice it that much. I had a 96 and didn't notice a huge difference but go for its. Inexpensive upgrade!

Good bang for your buck upgrade. A solid construction strut bar will make your steering more responsive and sway bars will decrease your body roll.

At first, when I installed my strut bar, I didn't feel much of a difference, but once I took it off, the difference was like night and day. Definitely one of those "you don't know what you got til it's gone" kinda things.

Are there better brands or are they all basically the same?

If you do a site search you'll find a lot of information on strut bars; it's not necessarily all dedicated to 6G, but 7G and earlier suspension geometry is similar so the concepts transfer right over. Here's a quick explination though..

Strut bars are a passive suspension upgrade, they lock the
the strut towers together and prevent the chassis from flexing outside the ideal suspension geometry. A good way to demostrate the purpose a strut bar serves is to drive one wheel up on a curb, feel the car flexing, that's what a strut bar reduces. In terms of overall performance they make a difference of thousands of seconds on a track car, so don't expect a huge performance boost, but your steering will definitely feel tighter. Neuspeed, spoon, cusco, dc sports, mugen and etcera all make great strut bars, but as long as the one you buy looks solidly built it'll do it's job.

Sway bars are an active suspension upgrade, they make a huge difference in handling by reducing body roll and oversteer. If your serious about suspension upgrades this should definitely be one of your first purchases. You can put on a GSR sway for a relatively low cost with a few oem parts, it's 14mm in diameter and will make a small handling improvement. You can step up to a 22mm ITR or aftermarket sway bar as well, they will make a bigger difference in handling improvement but you also need a subframe brace for anything over 19mm.

not really sure about strut tower in 6G, but since the anchor is high up on the fenders, maybe it could improve.
Sways - only the rear, no need to upgrade front, it will rather make handling worse changing the fronts.

i would have to upgrade my shocks and everything as well right?

You don't need to, but they're an integral part of your suspension so they would be my first purchase.

they are actually required when you upgrade springs, so if they are still working with the stock springs, should be fine unless car starts to be bouncy or too harsh in bumps, or leaks, etc, etc
