Okay......If your car HAS ZSP, it
already comes with different ZSP shocks to go with the ZSP lower springs. If you have ZSP and want to lower it AGAIN, then you should change out the ZSP shocks for aftermarket shocks to go with the new springs.
If your car does not have ZSP and you want to lower it, you should change out the your NON-ZSP shocks for aftermarket shocks to go with the new springs.
Anytime you change the springs, you should change the shocks, regardless if you have ZSP or not.
Another words, you need new springs and shocks to lower your non ZSP xi.
