1) There's no such thing as a 95 EK, the generation is 96-00 that's commonly referred to as EK.
2) Why are you getting specifically King springs? I understand King is an Australian company and you're from Australia too.
3) Lowering your vehicle on stock shocks will blow the shocks, trust me, i'm lowered on stock shocks and they're blown.
4)
It's advised not to lower the stock shocks in the first place, but if the owner decides to going lower than 1.5 inches, that's just ridiculous and highly NOT recommended.
-From my understanding King Ultra Low's are a 2.7in drop, and King Super Low's are a 2.0in drop.
5) I wouldn't recommend either of them as they're way too low and don't even mention a spring rate.
6) What's your budget, why are you spending around $260 USD for VERY BAD springs when you can spend less for decent springs for your car. If you just want to go LOW, and you have no care for your shocks and have less than $500 to spend, then I don't know what else to tell you.
7) If you do end up lowering you car, the rear will have some negative camber, to fix that here's a thread:
