what suspension comes stock on the GT2? It sounds like everyone is going for gt2 spec ride anyway. Can't you just buy that suspension?

 

made by H&R, but will not fit the Turbo.

 

what's different on the GT2? the mounts or something?

 

yes, the top mount being one of it.

 

there is no comparison btw the PSS9/JIC level and the Moton/Penske/JRZ level. If you don't mind spending money, a Moton/Penske/JRZ triple adjustable is the ticket. You can adjust the high speed compression soft to soak up the bumps but keep the low speed compression fairly firm to retain a sharp turn in. This is really the ideal street/track/anywhere setup if you know what you're doing.

 

Lou, I have the same question as you can see from my other posts. X73 is not low enough and not adjustable. Right now I am thinking of Pss9's at a height in between x73 and gt2 so i am not riding on bump stops. The other systems seem overboard.

 

yah, you could do pss9's and go 30mm lower than stock. That should give you some room to move, and it looks plenty low.

this is 30mm lower

 

i've been hearing good things about the jic's....

you can adjust the ride height separately from the spring rate?
i.e. they are set up independently ?

 

JIC is a horrible to deal with.

While it's just one individual that I know of, it's one person too many. This individual won a case in small claims court but JIC "appealed" and now I'm not sure where they're at.

Very poor customer service. Hard to get in touch with outside of their sales department. They insist they know more than the customer when it's clear they don't know wtf they're talking about.

And about slamming the cars... you're going to run into the same travel issues or lackof with other coilovers beneath the JRZ/MOTON/Penske level.

A lot of us street racers associate a harsher, lower ride as riding on rails or better than stock. Well, if it's riding on rails, you're not driving hard enough. And a stiffer ride does not necessarily equate to more traction, more speed carried through the turn.

Stock setup is probably the best suspension setup as it is backed by the Porsche engineers, but if you want to look better, then more research is required. If you're thinking you're going around the track faster with your aftermarket vendor, local tuner setup... then by all means, prove that it's better. I have NEVER seen anyone on any car board truly take the time to PROVE it. It's always speed by butt.

 

Lou... I've got the JIC's, and truthfully, while they felt solid at the track, they are definitely on the rough side for Chicago streets.

 

I do have the Pss9s for almost 3 years... they were installed by Orbit Racing in florida... Roger the owner along with his Pro drivers: P. LIEB & M.BARON(Porsche factory drivers- LIEB) actually helped to set up the car.. . and they said that they were comfortable with the set up... and thats after more then a couple of laps at Morosso road track.
I just wanted my car right, because I was pissed as to how the car handled at+ 130mph... especially after trading in the 1999 roadster diablo. As a matter of fact, Baron called me and said: its scary to drive ur car with the stock suspension". One more thing for you guys - Roger put on different sway bars... and finally decided to take them off... it did not do anything to the car... again, that the owner of Orbit racing telling me this. If there was serious problems with pss9s I think they would tell me. I do know however, that he did use some trickery to install them... Ie. changed and or modded some minor parts.. drop links, control arms and some bushings(please dont quote me) its been awhile...Roger even went as far as getting a brand new GT2 loaner from a florida dealer.... just to do research on spring rates, ride hights,etc.....and that was 3 years ago ...just when the GT2 came out. If anyone lives in south florida.... and ever visited Orbit racing... then you know the kind of outfit they run. If I had a gt3 rs cup car for $300k like Roger @ Orbit has for the Rolex daytona 24hour race( which they won 1st place by the way, 2004)... I would probably be fitted with the motorsport Motons. I live in Chicago, I mean Chicago- not suburbia, I dont think i would be able to handle Hard Core racing suspension like Motons.
I think its silly to get a $8k suspension, parts only, and just talk about it, unless u really put it to use at the track... and if thats what one does, then maybe a 996 Turbo is not the way to go... I would get a used GT Cup car from Orbit Racing($150K).... go and race....
... not trying to insult anyone ... to each his own.... I'm just sharing my thoughts.

 

Yes, the height adjustment is on a separate perch. You can go lower with the JICs than the PSS9s and still not hit the bumpstops.

I went with the 8kg/12kg weight springs. I think that Stephen has a more harsh setup. Correct me if I am wrong, Stephen. I also have the newest version with the helper springs. Of course, I have yet to put these on. Either way, I drive mine on the highway for the most part, so the "ride" harshness won't bother me as much.

 

I asked some time ago if anyone had the X73 ride height specs as they are not in the shop manual. I got no replies other than to do a search and came upon the numbers above. Some of these are INCORRECT. The manual, I'm looking at it now, states:

# USA Turbo
Front 158mm +/-10mm
Rear 163mm +/-10mm

# ROW Turbo
Front 138mm +/-10mm
Rear 153mm +/-10mm

# GT2
Front 118mm +5mm/-0mm
Rear 133mm +5mm/-0mm

If there has been an update to the manual indicating different numbers than those I've listed, or if the X73 is actually published, I'd sure like to know. The values I've listed are from 2002, 44-1 page 1.

Thanks,

 

JSM,

Last year I installed the X73 on my '03 TT. I live in central Illinois, so I understand what crappy roads you and I have to drive on. After 2 days, I determined the X73 was too stiff, with virtually no compliance. Every tar stripe or expansion joint I drove over felt like someone was hitting me on the top of my head with a mallet. I switched back to Stock.

Last week, I had the PSS9 installed and have yet to drive and evaluate it much due to the frigid temps. I can say that set at 9(soft) it rode smoother than stock, and much better than the X73. I'll be playing with the settings as the weather warms.

Cheers,

 

I'm running 9/12 springs for my JIC. And as far as I know, they've always come with helper springs. The amount of adjustment and the fact that the height can be adusted independently of the damper height was a big plus for me. Like I said, they felt great at the track, but are harsh on the street.

I suspect the harshness stems not from the spring rates, but the aggresive valving... I experimented with 3 different spring rates, and while the handling differences were apparently, the harshness never changed.

I've traveled pretty extensively around the country (and world), and I'd venture to say that Chicago literally has some of the worse streets one would ever encounter. Potholes the size of spare tires, uncovered trenches that look like bowling gutters, etc... and the city is under constant state of repair. The concrete formula used by the contractors here must be 50 years behind in technology, purposely, no doubt, so as to insure repeat business. There's another thread worth of *****ing here, so I'll stop... but, you get the idea. JIC + Chicago Streets = Punishment. I'd imagine if you live in a place with well constructed and maintained streets, that the JIC's would fit the bill just fine.
