i checked with everyone no body makes a strut. the gs are all shocks.the onlyone makes a strut is KYB. i can't understand why they don't sell them here. i have 71,000 on the car time for replacement.

I can assure you that there are many more coilovers/springs/shocks options for the SC430 out there.
The demand is too low and most of them are too expensive anyway, so no company here in the US is interested in importing them.

In your case, just get the new oem shocks to go with Swift lowering springs.
If price is your concern, Megan coilovers is actually not a bad option if you don't plan to spend a few grands.

 

You need shocks with your swift spring not strut.

i can't use struts with the swift springs?

 

Those terms (strut/shock/damper) are quite confusing as I do see different definitions on different web sites.
Lexus calls it shock in the oem parts catalog, so let's stick with that term here.

thank you for clearing that up with me.

 

Bacardi-maybe you didn't understand my first point down here. These are the Bilsteins you were looking for. Talwang is right...coilovers are much less expensive than what you are trying to do, but to each his own. There were several posts of IS/GS cars with Bilstein and Swift together, but no one has done it with SC's. I would take very careful measurements and get it in writing before you buy.

Good luck. Here is my post again:

you and talwang are both right. there is a big difference in the valving and from what i.ve been reading the valving would be all wrong they will not work properly. just going to put the springs on for now and go from there. like i said the swift drop the car .8 in front and .6 in rear which is all i want. the springs are made from a different materil and are much lighter about 60 lbs thats un-sprung weight..
