Strut and sway bars are two different things.

I have a comptech sway and tie bar on my car. I got the combo for $350 and it is, hands down, the best suspension upgrade I have done so far.

Neuspeed makes a great front strut bar. Rear tie bars are usually just garbage made for aesthetic purposes. Skunk2 and DC sports make them, but I would recommend the comptech sway/tie bar combo anyday over those worthless pieces of metal. Megan racing stuff isn't the highest quality, but it isn't the worst stuff out there. I would stay away from it, however, and opt for a more ridgid, brand name design.

Here is my comptech sway/tie bar combo:



Notice how much thicker the sway bar is over the stock one. Also the tie bar reinforces the chassis to prevent subframe tearout since the connection the bolts make is one of the weaker points of the chassis.
