The Dart came without a swaybar at the time I bought it, and it had a nasty tendency to suddenly oversteer while cornering. Especially on wet roads, the car would just ‘dive-in’ and the rear would break out. Better tires helped slightly with this problem, but it was obvious something had to be done about it.
After getting a used swaybar from a friend, it turned out to be one for earlier Darts. I tried modifying it for my Dodge, but decided to just get a proper made and sized swaybar instead. Looking at various swaybars, my choice fell on the Hellwig 1-1/8″ swaybar.
After mounting the bar the following testdrive showed a greatly improved ride-quality, especially when cornering. The car now pretty much went level through the corners and the nose-dive/rear-end breakout was gone.
