Anti-sway bars would be great. But it would be very hard to find. If at all they exist. As I posted in the Yahoo club it seems my rear shocks are a bit worned out because of the heavy weight I used to carry. Now my rear tires briefly lose contact with the road when turning quickly. So if anybody finds some shocks please let me know.
Controlling body roll is one thing - but if you stiffen up the rear without corresponding adjustments to the front, you upset the handling balance of the car and can make the car understeer a lot more...
Stiffening the rear roll rate will NOT cause more understeer. On the contrary, it will cause the understeer to be less noticeable and give the van a great feeling. I have added rear ANTI-ROLL bars (sway bars are something else) to several cars and have never been disappointed. One also gets improved steering response, which the Odyssey can use, in my view.
In the absence of an anti-roll bar for the rear, the use of Air-Lifts to stiffen the rear roll rate is another way to go. It is not a great solution, since it increases the effective spring rate and will roughen the ride somewhat. The feel, however, will be about the same. I speak from experience on this point as well. I hope this helps.
Jerry O is correct- increasing anti-roll stiffness on the rear will tend to reduce understeer. Depending on the specific car, this may or may not be desirable. Understeer at the limit is generally considered to be safer for the majority of drivers, so that is how most cars are engineered. Front heavy vehicles tend to understeer (or plow) by nature due to weight balance. My Accord has both front and rear sway bar upgrade (Suspension Techniques) among other things and the handling is quite neutral for a front drive car. I would say on the Ody, a stiffer anti-roll bar would be beneficial, hopefully someone will produce one and we can all find out!
By the way, the terms "sway bar" and "anti-roll bar" are used interchangeably, although anti-roll is the more accurate term IMO.
On the waiting list for my '02 EX Nav in RED!
