Is anyone running the Bilstein PSS9 Coil Over System?
 

<center><img src="http://www.bilstein.com/images/applications/pss9/pss9_pic.jpg"></center><p>How is it? any issues?
I'm thinking of upgrading my suspension and this is one of the hot contenders.

The other option is Stasis Engineering Track Sport Coil Overs - but from what I understand those are just normal Koni coil overs valved by Stasis?

From Bilsteins Website
A High Performance System with Sport Tuned Monotube Gas Shocks and Matched Lowering Springs

Evolving from a history of worldwide racing dominance, Bilstein has developed the ultimate automotive performance suspension systems. To insure maximum performance, these systems utilize Bilstein's superior monotube gas shocks, featuring:
Largest available piston diameter for greater sensitivity and precise control.
Patented digressive piston head design and deflective valving instantly reacts to changing road conditions.
Monotube design dissipates heat more effectively than a twin tube shock for cooler, more efficient operation and longer life.
Lighter weight reduces wear and tear on suspension components.
The Bilstein PSS 9 Suspension provides the ultimate in performance tuning. The fully-adjustable monotube gas shock absorbers offer a selection of nine precise compression and rebound settings, from comfort to competition. The front and rear progressive rate springs allow accurate adjustment of the vehicle ride height and center of gravity for the level of performance you seek.<ul><li><a href="http://www.bilstein.com/html/applications/pss9/index.htm">http://www.bilstein.com/html/applications/pss9/index.htm</a</li></ul>

Track sport is different from koni. Street Sport is Koni

I dont think so - Track Sport is Koni - only their Motorsport is Ohlins - See Stasis Website
 

TRACK SPORT

KONI Adjustable Dampers
STaSIS Double Digressive Valving
STaSIS Mounting Hardware
Hyperco Linear Rate Springs
Cadmium Plated Steel Damper Bodies
Height Adjustable
Damping Adjustable while Installed on Vehicle (rebound only)
* Customizable Spring Rates available from 450lbs and up.<ul><li><a href="http://www.stasisengineering.com/b5a4-s.shtml">http://www.stasisengineering.com/b5a4-s.shtml</a</li></ul>

I've had them on my car since 2001.
 

The #1 setting is the stiffest or most damping and best for smooth roads or the track. 9 is the least damping and has the softest ride which is good for street driving. The 9 setting still gives you more damping and a stiffer ride than their sport struts. Bought them for $1200 when they first came out but I'm sure you can get them cheaper now.

Track Sport != Koni coilovers
 

When I read your thread you said that the track sport stasis were basically koni coilovers. Which is not true. The Street Sport are Koni coilvers.

I only thing that is made by Koni in the Track Sport kit is the struts.

Track Sport:

KONI Adjustable Dampers
STaSIS Double Digressive Valving
STaSIS Mounting Hardware
Hyperco Linear Rate Springs
Cadmium Plated Steel Damper Bodies
Height Adjustable
Damping Adjustable while Installed on Vehicle (rebound only)


Street Sport:
KONI Adjustable Dampers
KONI Progressive Rate Springs
Cadmium Plated Steel Damper Bodies
Height Adjustable
Damping Adjustable when Removed from Vehicle (rebound only)

*Hides under Table* You are correct. My apologies
 

How good are the Stasis Track Sport suspension package? Is this the best option for the A4?

Its comparable to the other systems but..
 

You can have your own spring rates which is a plus.

Check out vogtland coilovers, it also has a review of the other coilover systems:
