You’ve decided on the Porsche you want to purchase, but you’re not sure which performance-enhancing features to look for. The fact that many of the most well-liked and practical factory performance modifications, such as ceramic composite brakes, electronic anti-roll bars, and air suspension, are extremely expensive adds to the difficulty of the situation. How can you tell which choices are best for you?
When you arrive at the dealership to take a test drive, be ready: Become informed. Knowing what you need and what you desire depends on your understanding of the functioning of the many optional pieces of equipment. If you are clear on what you need in a Porsche, you can specify the model that best suits your needs while remaining within your price range. To assist you, we’ve compiled a list of the five performance options that we believe offer the best value for the money, along with information on their costs and functions. Keep an eye on Of Note since we’ll be releasing them one at a time over the next few weeks!
PASM is a standard feature on certain of Porsche’s high-performance vehicles, including the Carrera S, Panamera Turbo, and Cayenne Turbo. However, if you have your heart set on a model that doesn’t come with it as standard, think about the electronically controlled suspension.
The PASM shocks have continually variable damping rates that react to driving style and road conditions in addition to lowering cars equipped with them by 10 millimeters. The ECU receives data from sensors at each wheel and uses it to change the fluid level in each shock to firm up or soften it. Depending on the model type and its specification, we often rate Porsche’s PASM suspension on any of its vehicles as outstanding to superb.
By pressing a button, the driver can select from a variety of PASM settings that modify the shocks’ predetermined damping force. For instance, when a 911 is driven in PASM’s Normal mode, the shocks are milder; when Sport is selected, the shocks are firmer for a livelier ride and improved stability.
Porsche does offer Sport PASM on the 911 if you desire an even sportier ride than what regular PASM gives. It sports updated front and rear spoilers, harder anti-roll bars, and shorter, firmer springs that lower the car further 10 millimeters. The Sport PASM bundle also comes with PTV or PTV Plus.

Has anyone installed Porsche Active Suspension Management (PASM) on a GTS 4.0 so that the ride height is dropped by 10 mm, making the vehicle 10 mm higher than a regular 4.0 vehicle and 20 mm lower than a Base Cayman?
Do you detect the change in firmness? I have no concerns regarding the ride height itself.
I own a 718GTS, however it has a 2.5L 4. The 10mm PASM is present. If it had been available when I intended to buy one, I would have ordered the 20mm lower version.
I’m pleasantly delighted by this suspension’s comfort and functionality. I genuinely enjoy it. I would definitely prefer the lowered version for track days, but once you get the hang of it and it rides well, this car will truly do some amazing things.
Regarding ground clearance, I have the Sport Design equipment in shiny black, which is another choice I never would have made. Its nose is a little bit longer than the conventional front end’s. Given that the 4.0GTS does not offer it as an option, I believe the 4.0 comes with it as standard.
My 2006 Cayman featured coil-over suspension, was significantly cambered for a street car, and was lowered. With that automobile, I attended more track days. Although the nose did occasionally contact, it just scraped a few pieces of the bottom, which could be easily and affordably replaced. In 80,000 miles, I only once replaced them. It’s true that the lower front of the automobile was unsightly, but it only becomes apparent when the car is being lifted. Who cares?
To the guy whose $200 nose piece had to be replaced, I ask, “WHY?” Did you not like how it appeared while riding the elevator? This is not visible while driving. Every sports car has a few nicks in the front. I’ve seen considerably more costly vehicles than ours with extensive bottom-nose scratching. Unless it falls off the car or something, it’s not a huge deal. It’s tarnish!
Driveways and recognized bumps should be approached from the side, not straight on. That is very helpful.
Get the 20mm if you want a sporty, tight ride. Just because you occasionally scrape your nose doesn’t mean I wouldn’t get it. This won’t kill you! Pick the one that will work best for your intended use. More days for racing? Get 20mm. Additional rides with Ms. Right? Maybe -10mm would lead to better acceptance… and more comfort on a daily basis.
The 10mm offers excellent lean control and is better at absorbing bumps, but shorter, stiffer springs are able to regulate those huge riding motions that come with dragging the car around a race course.
We provide you with a summary of Porsche’s PASM electronic active damping system and make a recommendation regarding whether you should add it to your vehicle.
The Porsche Active Suspension Management system (PASM) is an electronic active damping system that is standard on the most potent variants of Porsche’s current Boxster, Cayman, Macan, and Cayenne models but available as an optional extra on all of the lesser-powered vehicles. Additionally, the system is a standard feature on all 911 and Panamera models.
Porsche PSM (Porsche Stability Management), a stability control system that attempts to improve traction while reducing understeer and oversteer, should not be confused with Porsche PASM.
The PASM system includes a special collection of fluid-filled dampers, each of which is equipped with a valve that can be used to restrict the flow of oil inside the component, changing how stiff the suspension of the vehicle is. The driver can choose between two damper settings using a button located on the center console of the vehicle.
The damper valve is left open in Normal mode, allowing fluid to flow freely. According to Porsche, this environment combines performance and comfort. By closing the damper valve and limiting the flow of oil, sport mode produces a stiffer ride that, in Porsche’s opinion, improves handling.
Sports vehicles like the 718 Cayman and Boxster come with PASM, which lowers the ride height by 10mm. The technology can also be used in conjunction with Porsche’s air suspension system, which is installed in the Macan and Cayenne, to provide a ride height that is adjustable in six steps.
Porsche’s Active Suspension Management system, when available as an option, is priced in accordance with the model for which it is specified. It costs roughly PS1,000 for the 718 Boxster and Cayman; the Cayenne has a similar price point, but the Macan offers it for about PS800. For about PS1,900 on the Macan and PS2,600 on the Cayenne, the system on the two Porsche SUVs can also be specified with air suspension.
We’ve driven examples of every Porsche model that has PASM installed, and the feature actually alters how the cars drive noticeably. Depending on the specific model, Sport mode substantially improves the already remarkable body control, handling significant compressions and abrupt crests with ease. However, if you’ve also selected one of the larger wheel sizes, the damping may be a little stiff on UK roads.
We advise choosing PASM adaptive suspension if you’re interested in a Boxster, Cayman, Macan, or Cayenne and have the extra cash to spare. It gives the Cayenne more flexibility, the Boxster and Cayman more capability, and it transforms the Macan into one of the best-handling SUVs on the road.

This is a cross-post from a previous thread about spring rates, but it might be helpful to this discussion.
I requested a set of PASM springs some time ago so that I could compare them to my Standard chassis springs. Chucko, a CC member, performed admirably. I should also give Zornet credit for picking up the springs from Chucko one Saturday at 5:00 AM while traveling to the track. Givers, these lads.
Below is a chart with the test findings; in brief (all data for the 6 speed Cayman S):
1) Despite what some people have said, both the PASM and Standard springs are linear.
2) The standard springs tested almost exactly to the requirements indicated in the section above.
3) The PASM springs’ performance during testing was far below what was specified in the previous post.
4) The PASM front springs are around 7/8 in shorter and 13% stiffer than the Standard springs (175 lb/in vs. 155 lb/in).
5) The PASM rear springs are about 3/8 in shorter and 30% stronger than the Standard springs (297 lb/in vs. 228 lb/in).
We cannot make any judgments about the dynamic difference (effective stiffness, linearity) between the two chassis since we do not know the pace at which the PASM affects compression/rebound. We can infer that adding PASM springs to a conventional car will result in a higher spring rate, a softer ride, and no change in linearity.
You might not get a response because this is an old thread, and you might be restarting an old thread. Consider starting a new thread, please.
What is done by Porsche PASM?
Active Suspension Management by Porsche PASM, an electronic control system that comes as standard on the Porsche Cayenne Turbo, adapts the suspension system to changing driving habits and traffic situations. The new Cayenne and Cayenne S also have PASM as an option.
How can I tell if my Porsche is PASM-equipped?
The FAQ will answer all of your queries if you click on the underlined terms in this page for PASM or Sport Chrono.
In conclusion, both sport chrono and sport chrono without PAM are valid options. For each, there is a different button. If you have a PASM button (which resembles a shock), you have PASM; if you don’t, you don’t. The button is considerably simpler to find than wires coming out of shock towers, which can also be checked.
Describe Porsche PADM.
PADM, short for “Porsche Active Drivetrain Mount,” is an electronically controlled engine mount that is added on cars with the Sports Chrono Package.
How does the Porsche PDCC function?
Porsche Dynamic Chassis Control (PDCC) – what is it? Active roll stabilization is used by Porsche Dynamic Chassis Control to minimize lateral body movement during cornering. It can help reduce the vehicle’s lateral instability on uneven surfaces.
