My car has the PSS9 and I really regret it. I do drive it a lot on the street, and it's ok on the street. For the track the springs are too soft, especially in the front (260 lb front springs on a 996, 520 rear), and you can't increase them without getting the struts re-valved. I think the split in spring rates front to rear is just wrong. I'm going to have Bilstein revalve mine this Winter I think and I'm going to try something like 450/600 lb springs.
On the 996 (not sure on the 993) you have to add the cost of monoballs because the PSS9 springs rip through the rubber on the factory strut mounts. Part of this for me, I'm sure, are the pot holes and seams on 202 that just pound the suspension.
Kam, John R, John Giannone and I all regret the decision to use PSS9. I think I'd look hard at the JIC, it's not that much more money right?? Who knows with the value of the dollar these days. I think Mankowski has them and he's been thrilled. At least with them you can run softer springs and then if/when you are ready to go full track, you can increase the spring rates.
How much is PSS9 + camber plates vs the cost of JIC? Probably the same.
The PSS9 is an ok option, I'm just throwing out to consider the middle solution. The only risk would be if the higher spring rates would be more than you like on the street.
