Anyone know where is the best place to pick up a set of PSS9? price wise..
I would prefer SoCal so I can pick it up locally.

Thanks

I have never seen it anywhere else even close to Z1's $1499 price.

 

springrates seem kinda weak, and they use a progressive spring in the rear. Any particular reason you want to go with these coilovers?

 

I heard they got a micro-chip inside so it can self-adjusting the damper stiffness...
Is it true??

 

I've been in two cars that had PSS9 and I like the ride comfort the most out of the other coilover i've been in. I personally have been in Cusco, Zeal, JIC, and Tein. Although Tein may be close to PSS9 ride quality, but between this two I prefer Bilstein. Perhaps that's the reason the spring rate is lower than others.

I think the dampter is adjustable from the bottom, I don't believe they have a self adjusting micro-chip. But then again, this may be changed since my last research.
