http://www.gruppe-s.com/Subaru/subsus.htm Scroll down to "strutbars" and its the first item. It includes STi replica front and rear strutbars for $125. Do you guys think these will suck???
well the thing is.. i got the same replica once for my car, they r not as good as the real deal but they do help more then ur stock. and the once i have i got them on ebay for 54 dollers + 10 dollers shipping.. both front and rare.. struts...
If you are looking for a good handling upgrade, i would suggest swaybars instead. The wrx body is pretty rigid, and you prob won't see a big difference with the strut brace, at least i didn't.
rolling_trip is right... the front swaybar is real close to the firewall so its effects would probably be noticable only with HUGE sticky race tires with a real aggressive suspension setup... i've heard the rear strut bar helps some on the wagons though...
