Base 718 Clearance Dimensions

I have the Base 718 Boxster and I have the same problem. I have 20" wheels and I have to back out of my driveway at an angle and enter the same way. It was worse when I had my 911 with sport suspension. If I back out carefully I just slightly scrap the under guard but nothing more than that. It is a pain thought and I am not really sure how to fix it short of redoing the entrance to my driveway.

I also have the same issue going in and out of my driveway as well. I too have to go in at an angle and also at an angle when backing out and slowly ease it down, Sometimes I do not scrape the under guard but there are times when i do. Too bad they did not have the option to raise the front end just for this reason.

If need be, you can enter your car backwards

There is a plastic lip underneath. That is what scrapes, not the bumper usually.

Yes!!!

As Cash machine states there is a plastic lip (actually one on either side) to give you warning if the underside is about to snag. You still need to take care as they don't protrude a great distance but so long as you're being cautious & react as soon as you hear any contact you should be ok (they are there to provide warning & are very effective at doing so). The 982/718 Boxster's & Caymans just like the 981 models that preceded them are helped by the fact there are very short overhangs relative to the wheel positions. They are a great improvement over my old 987 Cayman for instance. There is a particularly badly designed traffic calming measure near to me which I simply had to avoid (make a detour) in that car (too high and a short steep ramp on & off. The front used to catch before the wheels had even hit the ramp). So long as I take it slowly it isn't an issue in my PASM equipped 718 or in the 981 before it.

I should add that those strip/lips are set quite far back & a drastic enough change in road / drive angle could still see your bumper catch. Best thing is just to get someone you trust to observe you in & check whether it's just the strips that are catching, but it is the most likely.

Thanks for the feedback and experiences. Does anyone have a diagram that shows the approach angle and dimensions? I remember seeing one long back for the 981, but I can't seem to locate it. I figure it might be close enough to measure against.

Being as height & ground clearance varies dependant on your suspension options it might be easiest for you to specify exactly what's you have on order & maybe a member with a similar car can quickly cast a tape on theirs. You really only need front bumper height, back bumper height & the height & distance from the front of the little protrusions underneath designed to catch first & provide warning. If your car is none PASM & none sport PASM but rides on standard suspension then you'll have the maximum ground clearance.

Base suspension, base model. No PASM.

Anyone with a similar car who could cast a quick tape measure & check the ground clearance for Nlongfellow?

It's raining today but if no one responds then I'll pull my 2.5 out of the garage as soon as the weather improves. If I measure that up then you can just add on the extra height yours will have over my PASM equipped car.

The front plastic warning strip is 7" off the ground and it's 33" to where the front wheels touch the ground.
At the rear the muffler pipe is 9.5" off the ground and it's 31" to where the rear wheels touch the ground.

I'm surprised that I haven't scraped more than twice--very lightly. We have some high traffic control bumps here and deep spoon drains (the worst for scraping) and I've only been a little more careful than in my Subaru Impreza.

Thanks! That's very helpful. Makes me feel a lillte better. The only specs I had was an older GTS that had a 4.4" clearance (per what I read online). I may be okay with that level of clearance.

There ya go Nlongfellow, I knew someone like GregW would jump in to help you. You just need to give some of us a little prod once in a while to wake us up! >

Where I live in India, there are more speed bumps and potholes than clear road......LOL! And including PASM, the ground clearance is down to 105mm.......nevertheless, I’m having fun on these roads......only mantra is to go super-slow on the speed bumps......sometimes criss cross.........my fellow Indian drivers happily wait or are busy taking pics of the car )
