Default Ground clearance / scraping issues?

My apologies if this question has already been addresses before, but have people had issues getting into or out of their garage/driveway because they have a high curb Or steep slope to their driveway? Don’t have my 992 yet, but did option it out with the front end lift, which I believe raises it about 1.5 inches....but still have some concerns that will be enough and possibly scraping? My M4 works if I angle it, but think the front end of the M4 is higher than the 992. If anybody has any ground clearance numbers for the 992, that would be helpful.

What have people done to alleviate this issue, short of moving or re-doing the curb? Does backing in/out of the driveway help? Seen info commercials on various curb ramps///are they effective/work?

Thx

Do a search on FAL, there are a few threads that discuss this. Here is my car in the factory with FAL active. Notice the height difference between front and rear, and I have SPASM so 10mm lower.

Thx. I have the PASM option (10mm lower) and Also thinking about the sports front facia, which is lower still, and worse, if you do scrape the sports facia, you aren’t scraping the little plastic attachment found on your car, but scraping the actual front bumper...and that could get expensive.

FAL is a cheap option compared to aftermarket solutions and if FAL won't get you over a curb, you have a bigger problem.

I agree. Problem is, I keep adding things to the build that keeps lowering the car from base. I just read that the PASM option lowers the stock car 10mm, while the SPASM lowered it a total of 20 mm (an additional 10mm from the PASM). 20 mm converts to 0.78 inch....which is about half the offset provided by the FAL. Is it enough, or should I back off on options that make my front end lower? Luckily, I’m not yet locked in, so I have time to digest the best solution.

I’m beginning to lean NOT to select the sports front facia option. I can handle a little scraping if it’s on a cheap piece of replaceable Front end plastic...but not if it involves scraping the actual front bumper facia.

For what it’s worth (I know not apples to apples comparison), and as best I can measure, the minimum ground clearance on my M4, compared to the 992 S, with PASM, is about 0.25 inches higher. As long as I angle my approach to the driveway lip/curb, I have never scraped my M4...so, with the Porsche FAL providing an additional 1.5 inch clearance, I should be fine. On paper, at least?

Thx

PASM is not an option. It is standard on base & S. So the only option (Sport PASM) is what will drop the car by 10mm.

SD front fascia has a painted lip that is identical to the SPASM lip on a non-SD car.

I don’t think the SD lip is any lower. The painted lip will give that appearance however.

I have the SPASM option with no FAL, and by taking a little care by taking driveways at an angle and by mostly backing into parking spaces I've had almost zero issues with ground clearance. On the one or two instances that I have scraped the front spoiler lip, the scrapes are entirely on the underside and are completely unnoticeable.

I take further comfort in the knowledge that even if I do manage to incur some noticeable damage, I can order a replacement spoiler from sun coast parts for $195 and easily replace it.

On the Porsche build site, for the 2021 911 S, under Performance Options, PASM (note, it is not listed as SPASM) is listed as a $1,020 option. It is, however, referred to as the “PASM Sports Suspension”...same thing as what you are referring to as the SPSAM? I have no idea? Maybe? I only care in the sense is the car lowered 10mm or 20mm? 10 mm for the PASM...but, as you say, if that is standard on the S, and I add this $1,020 option, is it lowered yet another 10mm, for a total of 20mm?

As far as the SD facia being any lower...well, in the Porsche description they specifically note that it reduces the “approach angle”. That could be because it’s lower, and/or it protrudes out more. Don’t know for sure? When I measured (granted, not scientifically), it appeared to be lower than the PASM equipped car with the standard front.

It would be very helpful if Porsche simply attached clearance numbers to these various options. They have for the PASM, ie, 10mm lower...but I don’t see any hard numbers for other options, such as the front sport facia.

Is that GT silver? That was my choice. If I can ask, what color is your interior?

The standard front facia has an inexpensive (~ $200) lip (if you prefer, a small spoiler) that is a sacrificial piece that can be easily and inexpensively replaced. That piece is NOT color matched to the exterior body color...that makes the process of replacing inexpensive. I don’t believe that is the case with the $3,000+ front sport facia option. When I looked at a read one at my dealership, I believe everything attached to the new design was color matched to red. Ergo, any damage due to scraping on this optional front would be more expensive to fix.

Unlike earlier 911s, the stock suspension on the 992 is PASM. It is not a lowered suspension since it is stock. You cannot get a suspension that raises the car. The sport PASM, we abbreviate with SPASM, lowers the car 10mm from the STOCK PASM height.

As for approach angle, do a search and you'll find the method used to determine it. You put a 3ft. board under the car touching the front tire and raise it until it hits the lowest part of the bumper or spoiler. Measure the height at the 3ft. length then go to an online calculator and it will tell you the approach angle. And, yes the sport PASM option does add a front spoiler that extends lower than stock, reducing the approach angle.

To be honest, if you don't plan on tracking your car or driving it at 8/10ths on winding roads, you don't need SPASM. Otherwise, if you do want it and are concerned about scraping, get FAL.

I would not have added FAL if I planned to just keep SPASM and not lower the car further. I track my cars and plan to lower the car so FAL is a necessity.

PASM is standard across the range, unlike earlier 911 series where it was optional. They confuse things by calling the sports suspension option 'PASM Sports Suspension' when really it's just 'Sports Suspension'. People here commonly refer to that option as 'SPASM' but it's the same thing.

So cars with the 'PASM Sports Suspension' are lowered 10mm from standard. For the 992 none of the cars are lowered 20mm.

OK, but for what it;s worth, Porsche, on their build site, does not refer to it as the SPSAM, just the PASM. Maybe they should. My dealership said that I am not the first customer to be confused by this labeling discrepancy. But I get what you’re saying,

Not sure what you mean that you can not get a suspension that raises the car? Porsche has the front axle lift option, to raise the front by 1,5 inches. Are you just saying that this is a separate system from the suspension, itself? OK.

As for approach angle, do a search and you'll find the method used to determine it. You put a 3ft. board under the car touching the front tire and raise it until it hits the lowest part of the bumper or spoiler. Measure the height at the 3ft. length then go to an online calculator and it will tell you the approach angle. And, yes the sport PASM option does add a front spoiler that extends lower than stock, reducing the approach angle.
From Porsche: “Note: SportDesign Front Fascia reduces approach angles. Active front cooling flaps are removed.” So, the question I would have is: Does Sports Design front Facia spoiler reduce the approach angle any more, or less, or the same as the spoiler found with the SPASM?

To be honest, if you don't plan on tracking your car or driving it at 8/10ths on winding roads, you don't need SPASM. Otherwise, if you do want it and are concerned about scraping, get FAL.
I plan to keep the SPASM in my build....as I do plan to track after properly broken in. However, to help mitigate scraping issues (at my house or speed bumps at a parking garage), I have also opted for the FL option. My only dilemma at this point is - if I opt for the sport front facia, will thatb additional lowering oof the “approach angle” then Making getting the FL option a mute point?

Porsche lists PASM under the standard features (not on the build site)--you can no longer get a car without PASM. In the past, you could, and it was 10 mm higher. You can option PASM Sport Suspension, commonly referred to on this forum as SPASM, that is 10 mm lower that standard PASM.
