    Planning my first F car this March, but worried about my driveway, which is 8-11 degrees over the 25 yards it covers (I was out there for a while today with a laser, a tape measure, a string, and a piece of wood - my neighbors probably think I'm nuttier than they did before). Planning on the Griots pad for the curb end, but worried the nose will scrape coming or going. Can't come in at an angle due to mailbox and mature plants (which may actually be rooted in the neighbor's lot, so I can't rip them out). I read that the F430 rides high, but would love a definitive answer. I feel confident that the ten degrees is accurate.

    Thanks in advance - love these forums!

    There's no straight forward answer to this question. You need to measure the car. These cars often leave with vastly different ride heights. I'm surprised to see how many cars I've seen over the years that has left with wrong setups. The overhang is 1100 mm, so you just need to measure the overhang height. From that you can calculate the angle.

    This brings up another thing. When you find your car, have your dealer go through the entire thing and measure the front and rear height, and do the alignments.

    Ask him to set the car to the Euro height, as that looks better, and it's how the car was originally designed to work the best.

    US heights are:

    Front 130 mm. Rear is 153 mm.

    Euro heights are:

    Front 129 mm. Rear is 151 mm.

    The F430 will scrape on almost any incline on a direct approach it seems. It is way better than an F355 or C6 Corvette Z06 though if that gives you any perspective.

    Appreciate the feedback. If I understand correctly, the nose overhangs the front edge of the front wheel by 1100 mm. If so, that means it can only take an angle of about 6.75 degrees at US stock height - straight on - without scraping. Bummer, but consistent with KM1959's warning.

    Appreciate the Bridjit link - that's a good price (largely because of the free delivery).

    I'm also surprised to read that the difference between Euro and USA heights is only 1 or 2 mm. Is that right? I'd expect it to take more like 1 centimeter to make a significant visual impact.

    Thanks!

    Yes. The overhang is measured from where the tyres contact the ground i.e perpendicular to the wheel center(in theory of course as the weight of the car flattens the tyre tread patch a bit). Everything from there on out, is overhang. You can't use the heights I gave you to calculate approach angle. Those heights are measured inboard on the chassis to set ride height and has little to do with the ground clearance of the front. You need at least 20 cm clearance on the front to clear a 10 degree incline, and if memory serves, I believe the ground clearance at the tip of the front bumper is about 18-19 cm. If you crawl in at an angle, you will get a bit more clearance, but that's of course only if that's possible. Looks like you need to modify your driveway entrance a bit.

    Thank you for the clarification. I had read the nose was about 18cm off the ground, so I was confused. With my new and improved understanding, it seems like it would only take about 6 degrees before it would scrape.

    Anyone with a 430 in Cary, NC can feel free to come and test it out for me!

    But I agree, it sounds like some kind of modification is needed. Maybe I'll just move.

    Thanks again.

    Approach the driveway at a 45-degree angle to dynamically shorten the overhang.

    As said previous, that is a possibility.

    With a 110 cm overhang and a direct 90 degree approach, it will hit on a 9 degree slope.
    If one goes at a 45 degree angle, it's like shortening the overhang to 78 cm. That will hit on a 13 degree angle.

    I'll have to relocate my mailbox and hire someone to widen the base of my driveway, but neither sounds insurmountable. I'm in a cul de sac so the whole "enter at an angle" thing is dicey as built.

    Plus add the Bridjit pad.

    Sounds worth it to me.

    Wish I still had my Vette for testing.

    Thanks to all for the guidance.

    Buy the car, get a few plank of wood.

    When car is here, try to see if you can get in, if not then use wood until a permanent solution is acquired :)

    I tried the bridge it ramps with no success. Then I built wood ramps. These worked well except that they slid around and I was afraid they would end up flipping and hitting my car. The final and permanent solution for me was to call a local asphalt company. They quoted me $550.00 which I thought it was a deal considering they sent at least 4 workers a dump truck and a supervisor to do the job. It took them about 45 minutes total. The wood piece in the ramp was removed after 24 hours to allow for water to flow thru.

    That will work. I would have used cement. Less of an eyesore

    That's what I did. I had to get race ramps made, which is a pain. But a larger pain would be not having the car.

    There are two kinds of F430 owners: Those that have scraped the nose, and those that will.

    I invested in Fabspeed's carbon fiber front bumper scrape plates for my 430. They cost $450 and are well worth it. They are easy to install and use existing bolt openings so there is no drilling necessary. They protect the underside of the bumper beautifully. In the month that they have been on my car, I have already heard that sickening sound twice. And that is with every effort to avoid scraping. Peace of mind, for sure.

    As a friend told me, "you have your priorities wrong, buy the car and get a different house". My drive starts at 10 degrees then drops to 5 degrees where a sidewalk should go then resumes its upward path at 15 degrees. My stock 430 will go up without scraping only if I approach at an angle and go very slowly. It will not come down without scraping. I built custom wood ramps to solve the problem. The city doesn't allow driveway mods that extend into the street here.

    Very fine solution indeed ! Problem over here: it would be absolutely illegal here to make something like this at all ...

    anyone have a picture of the skid plates? i noticed the under side of my 430 is a little chowed, like its white because the paint got scraped off.
