If you have PASM then changing springs would also likely include changing the PASM programming. The PASM chassis is already 0.40 inches lower and programming adjusts the shock stiffness based on Normal or Sport setting.

If you have the Sport Chrono package it will adjust the accelerator response, high speed cut off, PSM and PASM. All the triggering levels for PSM and PASM are lowered for optimum response to steering and handling changes.

The 997 RoW springs are different than the US so that might be a good place to start. Perhaps with 997 RoW springs and a changing a PASM setting with a PIWIS tester??

Quite a few people have lowered their cars with H&R springs. These seem to be the best quality for aftermart springs.

One issue you have to be aware of is that with aftermart springs, you run the risk of having a PASM shock fail since it reacts differently as opposed to stock levels. You'll know when, it fails in sport mode. The shocks get overworked due to the car lowered and the PASM software reacts to adjust the shock. Don't forget, there are MANY sensors on the PASM cars. All report back to the computer which then sends the valving to the shock.

I would look first at the RoW springs/euro setup that a dealer CAN modify the PASM. This way any issues can be covered under warranty.

One other way is to switch to the new Bilstein PSS9 coilover system for PASM cars. Very costly, but very big improvement in handling as well!

Another thing, some insurance companies will deny claims if they feel that less damage could have resulted by having the height stock. If they find the car was lowered, they can deny the claim.

I would also think long and hard about ground clearance. With the standard ride height on my 997S, I scrape the nose almost every day going in and out of fairly gentle driveways. While a lower ride height may look better, and with something like the PSS9's also handle better, it will also make the car a little less usable as a daily driver in my opinion.

agree with the comment on the ride height !

I haev the aerokit on mine, and I'm already on my second front spoiler lip

It catches on the most innocuous looking things !

I had the same questions but the guys at RUF said u could put H/R spgs on it and it would not affect the function of the pasm. i have an 06 997c2s. the ride after the spgs was just compliant and supple (at least to me) as the original, only the car looks muchhhhhhhhhh better. I do have to admit tho, that now when u hit the "sport" butten, the ride is verrrrry stiff (we wife refuses to drive in it if i hit the butten ha/ha) but the car handles like its truly on rails. i used it this past weekend at the PCA meet on the track and it was astonishing. overall, i recommend pretty much for all Ps b/c it just looks so much better.

As others have said - I'd avoid it for the following reasons: 1) Lower ground clearance = more damage to your lip, 2) Issues with shocks can lead to a very expensive replacement and then reversion to stock later, 3) I think the car looks perfect as it is now, which is lower than a base 997.
