Has anyone installed KW varient 3 or Bilstein PSS9 coilovers yet? They seem like they woud be a better option because Tein CS are
"cushy" and Flex is a bit stiff. KW is the top coilover in Germany I believe. I'm not going to track my car.

 

Their is one person that I know of with a Z that lives in Italy that has the suspension and one other person also with a Z here in North America, however he doesn't do the forum thing if you know what I mean. Unfortunately, a recent board change at my350Z.com means you won't be able to simply search for any usefull info. I do recall that the gentleman from Italy did like the suspension very much.

I just found out their is one G35 coupe owner that has the varient 3's on his car, he just did a post on my350Z.com inside a thread talking about Tein Flex coilovers. The KW's are going to be a performance notch above the PSS9's.

 

The Hipermax RS isn't too stiff nor too cushy. Rated at 8 kgf/mm both front and back.

 

are they Fully Adjustable?

 

The Hipermax RS features 30-way Dampening adjustability and ride height adjustability.

Key Features:
Single Tube Structure allows for greater oil capacity

30-way Dampening (Compression and Rebound adjusted simultaneously with just one ****)

Ride height adjustable

Valving is compatible with springs rates up to A} 2 (kgf/mm) of the included spring.

 

The KWs are fully adjustable, according to my350Z.com suspension facts "they are the only ones of their kind". I'm sure their expensive, maybe a group by is in order. I think these would be sweet on our G35s. Check out the KW website.
