Edit - also, curiously enough, pre 4/01 build ZSP sway bars are stiffer than the ZHP bars
All correct

The zhp ONLY has more durable/stiff ball joints. That is all that differs it from its same model year ZSP cars in the suspension.

BMW used better dampers and stiffer sway bars on pre-4/01 ZSP 330s. Everything after 4/01 was the same. Springs only differ based on equipped options if anybody is wondering (weight of the car varies slightly).
