FEATURES
-
The front suspension is similar to that introduced
on the 1994
Galant.
It is a multi-link structure featur-
ing two lower arms by which an ideal virtual kingpin

axis is formed. In addition, the upper arms have
been raised above the tire level to improve both
directional stability and ride.
