Hey, I've got the PSS9s on my Mk1 in combination with 996 RS springs. I've been very satisfied with that combination thus far, though I feel that the components from Tarett (www.tarett.com) have probably made a bigger difference to how the car behaves and handles than the shocks/springs themselves.

the Bilsteins are fine for the street. But not a great track shock.

It just depends on what you intend to do with them.

Bilsteins lasted me only 6000 track miles and they were shot.

I replaced them with Motons.

To add a European perspective. Ruf and 9ff both fit variants of the Bilsteins. Manthey Motorsports (who run the factory backed cars in the VLN events at the Nurburgring and elsewhere) offer a custom KW v3 kit that is highly thought of and Parr (Race team and Porsche motorsport importer in the UK) do a setup with JRZs. Motons are supposedly disproportionately pricey and are generally not used other than on racing cars over here.

Personally I still haven't clocked that much track time and will stay with stock until they need replacing. If that were today though, I would almost certainly go with KW.

what components from Tarret are you referring to?

Depends on what you want to do and what your budget is. There are plenty of used struts out there so you could find one and keep thing stock. Otherwise if you spend more time at the track than on the street go with Moton Club Sport.

I changed out all of the rubber on my GT3 (motor mounts, shocks etc), the twisty bits like links etc. Those changes make a big difference. The OEM shocks are just too soft for the track and the dampers not well matched.

Moton's are glorious but expensive. Fantastic, but beyond my reach.

A very effective and inexpensive upgrade is to swap out the springs and just have the OEM shocks revalved to match by Bilstein. I think the shocks were only about 600 dollars to revalve.

I changed to 650/850 springs with shocks matched by Bilstein. With that kind of spring rate, you might as well remove all the rubber mounts (engine and suspension). I can really feel the improvement from the solid mounts and don't find the car less comfortable for it. The car feels very connected without the rubber mounts.

After 55 track days on the OEM springs and shocks, I am absolutely SHOCKED by how much easier the car now is to drive on the track.

Yes... 650/850 is bit stiff on the street, but quite tolerable on all but some of the horrendously pot holed pavement around NYC (and most other cars are challenged there too).

By the way, the transmission mount is a wear component. Its very common to see those crack after some amount of hard duty. It should be checked. Mine was cracked. Wevo is working on a solid mount, so for now I replaced it with a new stock unit.
