Does anyone know if Bilstein came out with SC430 coilovers yet?

Nope. Already checked.
Teins are really nice though. I have tried both on my GS

just curious, of all the common "popular" companies, who have coilover systems for the sc430? i know the tein cs hands down the most comon, but what else?

I just ordered Tein CS Coilovers for my 05. Bilstein does not make an application for the SC yet..

I should have clarified a bit more. The Bilstein PSS coilovers for the GS DO FIT the SC430.

Odd that the spring rates are a bit off on the Bilsteins compared to the Teins:
GS Teins:
CS-front 504, rear 448=53% up front and 47% rear
Flex-front 550, rear 504=52% up front and 48% rear

So the balance of the above are similar front to rear

Now the SC430 Tein kit is
front 559, rear 336=62% up front and 38% rear=huge bias to the front

but...
Bilstein PSS for GS=front 685, rear 457=60% up front and 40% rear. This explains why my GS4 exhibited more undesteer vs the Teins I had on previously. In the SC this should not be as much of an issue compared to the GS.

So I guess what I am getting at is the Bilstein PSS for the GS appears to fit into Teins formula for the balance in the SC430.

In other words I am going to install my Bilstein PSS off my GS4 onto my SC430 this weekend as the load balance appears ok and with the adjustable rear Daizen sway bar I would have some room to adjust the suspension if it oversteers or understeers.

Sounds good on paper, in practice we will see. Perhaps someone could chime in and comment on my hypothesis. Could be that Bilstein feels the PSS for the GS is too stiff for the open chassis SC or most likely that the runflats woud even be worse off with a much stiffer suspension setup. Not sure but I will know more shortly. I should be getting my wheels next week and will install once I get back from Phoenix mid week.

Yes please post pics and your opinion on the ride quality.

Bilstein PSS run around 850-1000. High quality units. I posted a comprehensive review of them on the GS (do search).
Here is the pic of them off the GS and ready to go into the SC.
Will post more information once the install is complete and some miles and hard corners are done.
I do know that another member installed some GS Flex's on his car and ultimately went to the SC430 CS's. This most likely was due to the load balance being off on those GS shocks. I am loooking for something stiffer than the CS's so perhaps this option will work out.

yup, that would be genearch he had the gs flex on the sc430 before he changed it to the cs. he said that the car just didn't drive right

and now you can guess who has those tein cs
