Be aware that fitting lowered springs requires a shorter shock length than standard. IF you fit the lowered KING springs with your standard length shocks, KYB's, KONIs whatever, the spring will not be encapsulated. Or in laymans terms, the spring will be loose between the top and bottom end stops, and your steering will not work. It's not acceptable (or safe) to have a spring that comes loose when you the wheel clears the ground. To fit a lowered spring, you need a reduced length shock and as I've found out, these are not commonly available. I tried to fit the KDFL-04's with 25 mm lowered KING springs and the spring is loose. So I have hunted around and found some shorter KONI's that are no longer available.
I can sell you the KYB's that you are after but I'm wasting your time with shorter springs.
