I was going to say the same. I also believe they are called PSS (without the 9) Damptronics, because they don't have the 9 adjustment setting like non PASM struts and shocks.

 

The JIC on my 964 Track car with RS sways is a very nice track setup that is also somewhat comfortable on the street. My 997S is my street car that I enjoy also on the track. The OEM PASM suspension is good enough to allow me to see 150 on the back straight at Watkins Glen having been flat from the apex of T1 - so while it was hairy in the left hand turn cresting the esses, it held. My goal is to go one step further while keeping the PASM control, lowering 20mm to ROW sport height, and allowing adjustment of sways via the OEM GT3 units. If I were building a track dedicated 997S, I agree - I would not be using the Damptronics. But I like the idea of driving around town, changing tires and pads, and enjoying DE.

 

I was going to quote some of you guys so you'd know who I was agreeing with, but you all are in the same camp. Essentially, I was wanting to be the voice of "It's addictive, running on the track. And the Bilsteins that I have are not enough and here's why:" Know what I mean? Of course they are a step up from stock. Of course you'll think they're better on spirited drives and the occasional track day. I was just lending my experience with them not meshing too well with the track bug. I didn't know really what context we were talking about when the question was asked about 'track use' so I just gave my experience. Sounds like the Bilsteins that I have (PSS for PASM) or PSS9, as the box says (my order was in before they even released them) are better than the Damptronics because of the adjustability. So, you get what you pay for here. A 'next level' suspension will also be good on the street. You just adjust them for a sec. However, they don't work with PASM. Mine do (the Bilsteins) and it's an obvious change. I don't really think that mine have the 9 way adjustment though. I'd rather have a manual adjustment for rebound and compression instead of just ride height.
Again, just being the guy that has been there that's tracked a good bit. I bought a tow truck just for the track, and a trailer, so I know I'm not the average guy. Just trying to add what I can. Depends on what you want at the track. I don't think I mentioned, but the Bilsteins also bottom out a bunch on the track. I haven't been to Watkins Glen yet, so I can't compare. But I run consistent (like, 7 out of 8 laps) 2:14s at VIR with the Bilsteins with all the other mods. I expect the Motons and limited slip (same time installation) to get me into the 2:11 range. I know I'm good for 2:12 or 2:13 with the Bilsteins if I don't have traffic, which all of those 2:14s had their share of. I hope this helps. There's a big spectrum between street car and track car. I didn't really know where you were on that when I answered.

 

Blakt out,

What brand and type of limited slip diff do you have?

 

I honestly don't know where they get the diff, but I got it from Synergy Racing. My car stays there a lot. It's their race diff. You can check out their page at www.synergyracing.com. If you call, talk with Kerrigan Smith and tell him Jared sent you. It isn't in the car yet. They're taking the engine and tranny out right now.

Take care,

JC

 

Update from the shop... Porsche's parts system says the drop links for 997S and GT3 are the same, so the sways "should" have been a direct fit. Not so - took a call to Germany to get final confirmation. As mentioned in the thread - if you want to use GT3 sways, you have to change drop links front and rear, toe links, etc. What started as a $575 sway vs. $505 for H&R becomes a bit different, by about $1k. So, the H&R arrives first thing today and by about noon I'll be on the road. I'm sure I'll be fine with the H&R - with adjustment at the back, I'll still be able to tweak things.

Anyone else have alignment specifications they like? I know I'll be -20mm and will start with the rear sway set to soft for now. I'd been running -1.6 front -1.8 rear for street / DE camber, but the suspension mods / lowering is going to change things...

 

I got -2 front and -1.8 rear, toe inn front 2, toe inn rear 10. Will do the Cargraphic sway bars, made by H&R with Cargraphic specs, on monday. Will be testing on the Nordscleife in the week after.
