Ground clearance of 360

It is pretty low and may driveways are problematic. Rough estimate, you can clear a 7-8 degree angle, that's about it. Why don't you measure the distance from the wheels to the scrape point on the bumper (measure along the ground) and measure the height form ground to scrape point. From there it is simple math.

 

I don't have my 360 any longer but will measure on the 599. I can tell you for sure that the 360 is less than 6" and probably 5" but numbers for the 599 coming up.

The 599 with skid plates is about 3.5" ground clearance at about 24" from the leading edge of the contact patch. That makes it just over 8 degrees. The 360 is similar.

 

That should work. You will have to start or exit slowly because even a little bounce and you hit; think compression on the little lip into the gutter. I dropped a wheel off the edge of the curb coming out of the drive, cut just a little too soon. It dropped about 2" (not very much) but that was enough to have a hard strike that broke the mounting bracket loose from the bumper. There was no bumper damage on the outside so I had it taken off and epoxy the whole thing back together again. That was on my 599. Once you make the transition you can climb most anything reasonable so you can start and transition to as steep as you want.

One thing I did during our remodel was dig the garage down over 1" more so I had room for a lift. The lower pad also reduces the angle of attack. And yes, I can easily go up the lift, it transitions 4" up over 30" run.

 

On the 360 it's the front end that is the problem...for sure get skid plates added regardless of the garage. It the change in slope you're trying to estimate. Being an engineer I should be able to calc it but haven't done it yet...

I have not measured on my 360 but there is an August 1999 Road and Track article with all kinds of stats that seem to be very close to my car and it says Ground clearance is 4.2 inches.

 

One thing not being mentioned is that most 360's have been lowered in the front. You can expect the clearance issue to be different with each car depending on if it was lowered and by how much.

 

I had a deep (26') single car garage built 7 years ago.
My car is lowered (by PO) to the point where I am contemplating raising the front a few mm this summer
Don't know if these 2 pics can help with your decision

That looks like about 9.5" rise over about 5' so 9.11 degrees. That is right in there for what I posted and probably near the limit for approach. The nose JUST clears on the way in doesn't it.

 

Yes, it's close but it clears it

 

I had a similar issue with my driveway access, this may be of some use? Measurements are in millimetres. Image Unavailable, Please Login

 

I suspect your angles are wrong. It looks like you calculated them based off the length of the car, location of the axels, and ride height. The low point is actually closer to the contact patch than the nose of the car and the front edge of the contact is farther forward than the axel so the angle is steeper than what you would have calculated.

 

You are correct, I did this to give me clearance when designing my driveway entrance.
I went and measured the lowest parts on my car (standard 360 spider) and these are the points which will make contact
* Front: distance from wheel centre 900mm, height at touch point 130mm = 8.2°
*Rear: distance from wheel centre 584mm, height at touch pint 178mm = 16.9°
*Lowest height measured between the wheels, chassis to garage floor was 125mm

 

Yes, you have it right. You will get slightly more than these numbers because of the size of the contact patch. You will have to make the transition very slowly because even a little compression on the suspension and you will scrape. And yes, that is the voice of experience.

I say excavate down some to reduce the angle and to make extra height in the garage for a lift.

 

As John already guessed, it is 9-1/2"

 

That should work, but you’ll have to enter slowly. I ended up having 7 degrees (worst area) to play with on my driveway but it will still scrape if I enter too quickly.

Wow, that's steep.

 

It is sloped leading into it though.
