sway bar

if i put in a rear sway bar, do i need a lower rear strut tower brace?? also, will just the rear sway bar make a diiference in the handling and body roll or would it be better to put both the front and rear sways??

adding a rear sway bar or putting in a stiffer rear sway bar reduces understeer that is inherent in most FWD cars. You don't need any kind of strut brace to install one. If you put in a thicker front bar and a rear bar, then you will just be reducing roll and increasing stiffness, but not dialing out any of the understeer.

with the rear sway, should i also put a lower rear tie bar?? does it make a difference whether or not i have the front sway bar??

your car already has a front sway bar, I would not suggest upgrading to a thicker one unless you are experiencing oversteer though.

a lower rear tie bar may also help reducing understeer as well.

drdisque is correct, a larger front sway is going to be overkill. If you are a spirited driver the rear tie bar may be a good call.

Yes you should use a lower tie with an upraged rear sway to prevent frame twisting.

Keep the stock front sway and upgrade to poly bushings & shorter endlinks.

will polybushing decrease the ride quality?? and don't bushings squeak?? is there anything else you'd reccommend??

No they won't decrease the ride quality.
Yes they can be noisy if not lubed right. I spray mine every oil change.

Front & rear upper strut bars.
