This was just a thought I had in regards to lowering PASM equipped 997's. Is it possible to custom fabricate a clamp that can be used to squeeze two coils of each spring to a desired ride height. Maybe a clamp for the two upper coils and the two lower coils of each spring to bring the ride height down just a half inch more than stock. This clamp would have to be made out of a very strong piece of metal to sustain the 1500 lbs/inch (maybe more) strength of the coil. This may sound stupid, but let me know your thoughts.

 

That would probably wreak havoc on the valving of the shocks and utterly destroy handling.

 

SInce the 997 will be available world-wide, and the US suspension settings will likely put the car a little higher, would it not make sense that ROW 997's with the PASM suspension will set lower? If this is the case, I would think (hope) that Gert would be able to get us the different parts to make ours the same height as the Euro (and ROW) setup.

How about it Gert?

 

SPAM equiped cars apparently have the same ride height worldwide.

Go for a base 997 and wait for a PSS-9 kit.

 

Indeed, PASM cars have the same ride height worldwide. The Euro -20mm susp does not have PASM. It is a sport suspension without the ability to adjust dampening from the cockpit

 

I put more thought into this thread I posted and I think it is a terrible idea to use clamps to squeeze stock springs. I guess I will have to be patient until someone comes up with a mod for the PASM.

 

The Cayenne PASM is adjustable via and ECU modification. Is the 997 capable of this too?

 

PASM on 997 is very different from PASM on Cayenne.

PASM on 997 has no ride height adjustment - it's not a self-levelling suspension - it just has adjustable shocks that can range from soft to hard damping using wheel sensors.

PASM on Cayenne IS self levelling - useful for a pseudo sport ute - that uses ride height sensors that allow the truck to change ride height according to terrain.

It doesn't mean that someone won't come up with a 997 PASM system that uses shorter springs, but you would then need to recalibrate the shocks, all of which cost significant chunks of money to reprogramme and test. On top of which you also have to ensure that the new programming interfaces with other systems properly like Sport Chrono. And of course has no safetly related bugs in it...

Nor does it mean that Porsche might not offer a GT3 suspension factory fit option on the 997S after that car has been launched.

So buy a standard 997 and mod it, wait for a 997 GT3, or wait for a possible factory fit GT3 suspension on 997S.

Porsche has also stopped you putting in after market seats, like GT3 style race shells, as they now fit seat mounted airbags which means you would screw up the programming for the other safety systems if you took the standard seats out.

 

The 997S sits .40" lower than the 997, because of the PASM. I don't know how either one compares height-wise to a stock 996 or a 996 with ROW M30 suspension.

I test drove a 997 (non S) yesterday, and it was a really nice car. It was equipped with PASM and the sport setting felt pretty good.

 

Peter from Wheelexperts has announced that Techart is making a lowering spring kit that is PASM friendly for $550.

 

I checked with Gert about it, and here's what he had to say:

"I checked the differences between the Euro and US PASM and the only difference are the springs. All the other parts (shocks, bump stops, spring tops, control units) are the same for the Euro and US 997 with PASM.

"There is not much known about the PASM so I cannot tell what will happen if you swap the US springs with the Euro springs."

 

Techart must have tested their springs with the PASM before selling to the public.

 

The Bilstein is better than the stock 997S suspension? Why doesn't Porsche makes a suspension that doesn'[t need to be changed?
