I realy do have to reccomend KYB Excel G. Theyre pretty cheap and do really really well, up from that would be the KYB AGX, theyre supposed to be awesome.
The KYB Excel G out did my Koni yellows, i didnt like the Konis at all in the VR4, the KYB shit on them.
As far as springs, kings are good, but they wont offer you great performance as theyre usually suited to off the shelf road going type applications, springs minimise body roll, whilst shocks control the spring....to a degree.
Id look at the best spring you could afford, like an eibach or H&R, even the hotbits springs look good, theyre cold wound as well.

Call them if you dont see a part isted.
With the Kings, if you wanna get rid of the Kite stance their springs give, get
KCRL-29 for the rear,
and either a KFFL-80 or KFFL-25 in the front, cant remeber which it it, either way, its an AV Telstar spring.
I played around with ride height combos from them on my VR4 and GGSR for years.
Oh, and if you buy the KYB's, get the Galant GSR part number (for front), the spring seat sits lower on this shock compared to the VR4 one, and there will be more travel whilst able to sit lower, its about 10-15mm difference..and use a very good bumpstop, espesh in the front.
