    Anti- roll bar

    Stiffer front ARB (anti roll bar aka swaybar) will tend to improve steering response, but a few metres into the corner the car will undesteer more than with a softer front ARB. A stiffer front ARB will also cause the inside front wheel to unload more when exiting corners.

    I've completely removed the front ARB on my CB7 and much prefer the reduction in understeer. This (removing front ARB) does affect turn in sharpness, but you can sharpen it back up by stiffening up the front Konis (and pumping up the tyres). Removing the front ARB causes a surprisingly small increase in body roll, but a significantly large reduction in understeer.

    Typically, for front drive cars it's better to increase rear ARB stiffness as this reduces understeer.

    Something worth noting with these Accords (CB7 / CD5), but seems to be esoteric knowledge; the two brackets that hold the rear ARB to the rear subframe are very soft and flex a lot (not the 'D' clamps that hold the 'D' bushes, I mean the two brackets that attach to the subframe with three bolts). This is more of a problem the stiffer the ARB is.

    This bracket flex behaves very much like you have very very soft ARB rubber 'D' bushes, and even if you fit harder poly D bushes here you still have this bracket flexure causing the ARB to act (at least in the initial phase of roll where it affects steering and handling response most adversely) as if it were substantially softer than it actually is (even if you've fitted a stiffer aftermarket ARB). The only way to fix this it to take the brackets out and re-inforce them by welding in extra bracing and thickness to the existing brackets.

    To make matters even worse, where the rear ARB attaches to the trailing arm is poorly engineered (unless you want to 'dull' steering / handling response, which the designer may have wanted to do considering these aren't intended to be 'sports' cars). This also causes the ARB to act as if it were less stiff than it actually is.

    The problem is that the 'stud' on each trailing arm to which the ARB link attaches is not properly braced, and as loads are passed between the trailing arm and the ARB the manner in which the stud is attached to the trailing arm causes the trailing arm to flex (the metal actually twisting to some degree). To fix this requires a brace to be attached to the inner end of the 'stud' and to the bottom edge of the trailing arm (triangulating the inner stud end to the bottom of the trailing arm).

    When I stiffened up all these brackets and mounts associated with the rear ARB, there was a very significant improvement in steering / handling response, and in initial body roll, i.e. body roll is significantly less especially at lesser cornering force (i.e. lower lateral acceleration), as well as at higher accelerations (though it's still too much at higher accelerations as it still needs a stiffer rear ARB).


    I believe I found this on honda tech or some where and this might explain why the back end of my car is a bit sloppy or it has a small sway when going through a solemn or different kind of corners. I was wondering if anyone agreed or disagreed?

    This was a good read. It all makes sense to me, so i'd agree with the info here...

    I just installed a Progress Rear Sway-Bar and the difference in road handling between that and the OEM EX sway-bar is very dramatic. I said in another thread that the difference going from the EX bar to the Progress bar was more noticeable than going from no sway-bar to the EX sway-bar. And after reading this excerpt, i now see why...

    The progress bar uses a better mount design, in regards to the crossmember to sway-bar brackets. They are MUCH more solid, as are the endlinks.

    Definitely some enlightening information. Food for thought for those interested in a rear anti-roll bar.

    I'm not sure about removing the front sway bar....anyone brave enough to give it a shot?

      Didn't you sell your Accord?

        It is pretty well known that reducing roll stiffness in the front a FWD aid under steer problems. But with more roll you transfer more weight to the outside tire resulting in a greater change in alignment which can be either good or bad depending on what you want. Transferring more weight to the outside also reduces total traction in the front end and therefore reducing effective cornering force. That can also be good or bad depending on your setup, what you're driving on, and how you're driving. So it's a trade off, less under steer, or less overall traction.

          Thats if you don't have the right spring rates...Ideally its preferred that no sway bar is used, because the sway bar will pick up the wheel and decrease overall traction... but to run spring rates that would work with no sway bars will break you back in half and blow your kidneys out.

          I freaking love the progress rear sway bar. I have a 10th anniversary edition which came with no rear sway bar and it was a world of difference.

          Jerrett I did sell my car in may, but the guy i sold it to was putting neon lights everywhere and was making a disgrace of my hard work not to mention the mass amount of money in the car. So when he lost his job I offered to buy it back from him at a quarter of what I sold it to him for (douche move, but he shouldn't have slept with my girlfriend) So now I am back on the war trail to the track...

            is there a diffenrence in the Progress Rear Sway-Bar which is 22mm than the suspension techniques that is 21mm. does 1 mm make a deference. theres a 50 dollar deference between the two of them.

              There won't be any difference really... 1 mm of diameter won't change anything physically noticeable. I would say for 50 bucks go for it.

              I had to get the progress rear bar because I didn't feel like piecing together a rear sub frame so I could have a stock sway bar, and the progress you make your own holes through the existing sub frame to mount the d brackets.

              What I have experienced with the 22mm bar on GC's and Koni's are a very neutral set up and it handles great...though if its wet or the corner has a negative bank you WILL get over steer, but easily controllable

                The flatter the vehicle is the more available traction you have. Tires have a traction curve where the maximum cornering force available has a peak. You can increase the force on the tire and increase the traction to a point, once more weight is added the traction added begins to increase at a slower rate. The more the vehicle rolls, the more weight is transferred to the outside tire and the tire becomes overloaded. The cornering force does go up on the tire as more weight is added, but it is over it's maximum efficiency range and the inside tire is below it's efficiency range, thus reducing maximum available traction.

                A 22mm bar compared to a 21mm bar is 20% stiffer. It is also mounted to the chassis much stiffer than using stock mounting locations. That won't translate to a 20% increase in handling, but it is a significant difference. If you drive the car at it's limit often, or use the car competitively where under steer is a prominent issue, then definitely go with the Progress.

                  I removed both sway bars on my CRV. It rides much better without them since they were limiting travel. As far as handling, it didn't make difference as far I could tell but then again, I don't race around corners.

                      Yea, my car used to run really smooth with stock sway bars, now with the ST in the front and Progress in the rear it is super stiff.
