I want to keep my car at a legal height but still want to lower it as much as possible, what springs would you recommend i get? like the types of one and a good brand that's reasonable price. thanks

Ultra lows cut in half...

On a more serious note, because EF's are pretty jacked up to begin with you've still got pretty good ground clearance (IE over 100mm (legal)) with Ultra lows in the rear and Super lows in the front. If thats too low, then try Standard lows in the front and Superlows in the rear. I am recommending staggered sizes because of the generally higher rear end of the factory springs. With any kind of lowering on an ef also take shocks and removing mud flaps into consideration as the will bottom out and the muddies will tear off!

As far as brands go for price and sizing options go King Springs, if there is a distributor near you try get them direct from Kings Springs. Lovells are cheaper but offer few sizing options and I have personally seen a few lovells products fail and have pretty large tolerences side to side, one side of the vehicle was 15mm lower than the other, when its meant to be more like +/- 4mm-5mm.

Also there is a wealth of information on the topic if you hit the search button.

If you've got car insurance, you might want to check how low you can go (without saying who you are of course). For example, RACV will only allow 35mm below the ride height of your original springs.

Do you tow any trailers, or have 3 'big' mates sitting in the back occasionally. Going too low will mean you're going to scrape on road humps & steep driveways. Also consider what's more important to you, looks or ride comfort. I bet there's a few guys on here that can tell you how uncomfortable Ultralows are on rough roads.
