That and earlier gen civics had a bad habbit of having their lower control arm mounts ripped out on cars running large anti-roll bars... the Tie bar aliviated the problem. Note that this was on cars that saw alot of track time (Wheel to wheel and Open track). I dont konw of any one having that problem with the current gen civics or RSX, so we may not need one... but for a few $$$ why take that chance?

Autocross: Because Life is more fun on three wheels......
"I know Solo only comes one minute at a time, but what an intense, non-stop, fast-forward car control exercise minute it is. Sure, the velocity is higher in road racing, but inside the car it is slow-motion in comparison. In Solo, the turns come like machine-gun rounds. "

The way the sway bar was attached was different. It was on the LCA vs. being on the trailing arm like it is now. My guess was it was much more active mounted on the LCA and the subframe had to bear higher loads due to it. THat and the LCAs were shorter on the older models (more moment arm between the LCA bolts).
Theres allways going to be a little flex in the chassis, just not all that much to warrent the necesity of a rear upper tie bar. If we had McPhearson struts on the back I'd say get one absolutely.. But with double wishbone your better off spending $$ on something else. when you get down to trying to find that last 10th of a second it may be worth it.

there is flex, but not like in other cars. The rear struts are in the trunk which means they are pretty much connected by the trunk metal. That is where most of the flex will get absorbed so adding another brace on top of that won't theoretically do much. If you add a C-pillar brace, that will help the flex between the c pillars because there is nothing between them. Some people make trunk bars too but they don't do much. Do you get what I am trying to say? Bracing flex means filling in the gaps between places that can bend, like between the front struts, in the interior of the car, and in the trunk. You can also brace the chassis from underneath by using x and u braces.
if you are looking to save .0003 of second, then most bars will do some good if they don't add too much weight.

The front's look easy. as long as I don't put them on backwards like the roll bar it will be ok. . I was talking about the struts, were you talking about the control arm bushings?
I know I had a blast!!!
