If you want more track (road course) worthy coilovers, then look at the STaSIS Tracksports. If you want track ***** status, get the Penskes or STaSIS Motorsports (Ohlins).

every thing else is barely better than stock sport, imo, except that it lowers the car for better control but rebound/dampening isn't enough. skip all spring/shock combos -- go straight to coilovers.

the KW3 and H&R ultras are just too stiff and not enough shock, imo.

upgrade your rear sway unless you gain more spring rate in the rear (150-200), then you can just run the stock bar.

If you want a more aggressive setup or do much track/autox, save for the next level up... depends on what you are doing with your ride... Streetsports were perfect for me, as my ride was street driven only this year. Spending more would have been a waste for me... need to buy other stuff too! ha-ha.

From what I have learned... They are a Koni based coilover but adjust dampening from Stasis.

The S4 models make them a tiny bit stiffer than the A4s. They still have a better ride than the A4 tracks.

yes, they are progressive springs

My K&W setup works real well w/HSports and is very adjustable
