The best front and rear strut tower braces are from Road Race Enginieering ihere in California. Only problem being they make them on a custom basis and you have to bring the car to them. Your next best bet for the rear brace would be Probesport.com. The owner Ken has all of the parts made and is an enthusiast like us. May take a while to get the parts out to you, but they are inexpensive and top notch quality. Most of the front braces out there aren't all that great but there are a few good one. FAST and Mazdaspeed come to mind, you can get both from http://www.corksport.com. If you really want to tighten up the car's handling though I would invest in a new rear sway bar it'll do more than any of the braces. Addco being the most popular.
