Default Will it scrape

Have a math question and need help. Entrance to my driveway is 73 inches long and has an elevation of 7 inches. I believe that is a 10% grade (?). Will a 991.2 4s with Front Axle Lift clear the driveway?

I think you'll be fine, but one critical question is: Can you take the incline at an angle? And, if so, what angle? Sport Design front fascia does not help you.

Rise over run. I am not sure I understand your numbers - are you saying that over a 73" run, your driveway has a change in elevation of 7"? If so, then this should be a 9.6% grade. I can't answer the scrape question but at least we can confirm the numbers for someone else to give feedback on.

The 4S does not come with the SD front bumper unless it is ordered with one. Otherwise, you will not scrape.

This is true. I have the sport design with SPASM and FAL.

Even without FAL I have been surprised as Bob Z mentioned.

My GT4 didn't come with FAL (wasn't an option). I was worried but I never needed it. Then, to play it safe, I specced my GT3 with FAL, as I thought it may be lower with a longer nose than the GT4. Again, I never needed it. Can't imagine I'll ever spec FAL again. It's big deal among the GT3 guys for resale but I doubt half of them who have it ever use it but once in a while. With a little patience and good judgment, you can take most inclines at an angle with no problem at all.

In Los Angeles, there are lots of crappy roads with dips and uneven driveways. My m3 has so many scraps underneath and that car is not even that low.

Tks for all the responses. I’m actually buying a 992s with FAL and have to decide if I can order the Sport Design Front. I used a 991.2 as an example since obviously no one has a 992 yet. I believe the ground height is similar but I will check that out. I recalculated the driveway angle and it is 11.5 degrees. I can enter at an angle going in from the Street so I think based on other people’s responses that I’m ok.

No point in doing the math until you have the 992 measurements. The car is so different from previous 911s, I wouldn’t assume figures will be the same.

I scrape in my driveway without FAL in my GT3. Use it every time I drive. And the driveway is not that steep (my Elise went up without scraping).

Now it is time to head over to the 992 Forum.
