those seem somewhat soft spring rates. wonder how they will perform on the track.

 

spring rates really matter very little - it's the interaction of the spring and damper that determines overall feel and performance. This is why some coilovers with what appear to be more "trackable" spring rates, often fail miserably and are slower overall. That being said, these are not designed nor marketed as track coilovers, they are designed to be performance street oriented units that can be taken to a track. In other words, if you were building a full out, 100% race car, with all the trimmings, out of the box, these might not be the best overall setup. But that kind of car is a far cry from someones daily driver, or even weekend toy, that sees a few club type track days a couple times a year. IMHO, the latter is by no means a "track" car.

 

Are these going to work on my 2007 Z? Thanks.

 

yes these fit all 2003-2008 350Z coupe and convertible models

 

there really is no comparison that can be drawn, they are different units designed for different customers

 

So for someone that will be doing spirited driving but looking for a fairly comfortable ride the PSS10 is better?

 

if given the choice between those 2 units, yes, the Bilsteins are what I would run on my own car...really comes down to your budget though, as these are not really priced for the same consumer

 

But they are probably comparable to RS*R coilovers in price quality and use... any ideas?

 

sorry I don't know anything about RSR coilovers

 

I've had a set of PSS9's on my car for over a year now and I couldn't be happier. I cannot compare the ride to other brands, but I can tell you the ride is a bit stiffer than stock. It's more controlled feeling though. Drop was 1.5 all around. Limiting factor wound up being the rear spring adjusters. (If you remove these adjusters completely, a 2" drop is expected).

I'm about to get into Autoxing soon. I wish I could comment on their performance at the track, but I haven't been yet.

Here's car how it sit's now.

Bump ... If I had to do it all again, I would buy PSS10 for sure!
