You do relaize that a strut tower bar does NOT make your ride any stiffer, right? The only thing that it does it reduce strain on the unibody by dividing the force among both posts rather than one. I have all the physics to back it up, too. I forget the link to the article, but it was a BMW M3 enthusiast website and it all makes perfect sense. The only reason why you need one is if you put a lot of mileage on your frame, and if you're under very stiff, high-stress suspension.
If you want to improve your ride, I can't recommend enough the tokico struts, eibach springs, and GC goodies to match. Made my EGT 1000 times better...
Well I have no effin clue whta Greg just said, but let me just say this... after driving the Escort, and then the Civic... the civic will hold the corners 10 times better. Yes I know, it's 8 years newer. but still. I'm curious as if Beav has a front upper brace on his Wagon.
Strut braces keep the frame from flexing, which in turns keeps both wheels on the ground, giving you a tighter, crisper feel of the road in a hard corner.
I cannot wait to get my suspension completely done up on the Si. It's going to be sick as hell.
I recommend the corksport strut tower braces. They cost twice as much but they are far better than the cheapo ractive ones. If you want a cheaper option, just get a vibrant brace off ebay for $25. It's almost identical to the ractive.
