you can piece together a setup using brand new KYBs and some used OEM springs and new topmounts for less/same as strutmaster. (250-350 for KYB shocks, ~$100-150 tops for oem springs (250-300 for some H&R for a mild drop), $60 for all the isolators/bump stops, and ~$160 for new KYB upper mounts.)
After a quick search on Ebay and a few other sites the only shocks/struts I am finding for the LS400 all say "excluding factory air suspension". Hope this is not the case with coilovers as well.

That refers to using those parts with the oem air susp, not if you are converting to a sprung setup.

OTTO. Oblivious to the obvious. Thanks. Ever heard of ISC N1 coilovers for the LS? I have seen these on a couple performance websites.

I notice on Sewell that Lexus also carries a OEM Rough Road Package spring for $10.00 more then the standard OEM. I guess this would be slightly more firm ride, yes?

Part number:
4813150110 - front
4823150140 - rear

i may be mistaken (Kansas may know better) but I believethat it doesnt firm the ride up so much as it raises the car ~1/4-1/2".

Interesting, because they are more $$ than entry-level megans like the Street series. From what I have read the N1s are from Thailand?

Just like Hiroshi stated, I would also like the option of having the car lowered when its parked up but I would like it at normal driving height when im driving.
How can I achieve this ?
Here is what is happening to my car
