Good. Now that we've got a baseline, the ZSP suspension on the 323/328 is similar to the pre-4/01 ZSP, but significantly different from the post-4/01 ZSP, and ZHP suspensions on the 325/330. Compared to the ZHP suspension, the 323/328 ZSP suspension used higher quality dampers (but with similar valving), stiffer swaybars, and used spring rates are similar to slightly stiffer than comparable ZHP cars.
