Mine has the stock spacers removed and P7 225-50-15 front tires. It measures 3" under the radiator support, without any loading.
IF you use a skid plate, put it under your floor pans to protect your buns. I have lowered floor pans so there is always a butt concern in mine. So is a front skid plate which I may have to do in steel of significant thickness now that I think of it?
The lower skin on the nose has been replaced twice so far.
It measures just under 42" to the peak of the roof and for all intents and purposes is at GT40 race height. 40" was the minimum a "40" could be.
You need to learn to drive differently this low and look down the surface of the road for firm obstructions like iron manhole rims. Here, they are like unwanted nose hairs and just appear suddenly and unexpectedly.
I do not have the air bag front shocks but it's a consideration and an acknowledgement that may be inevitable.
You can scope out the route in which you intend to travel but here in the eastern US, there is constant repaving going on overnight and you will commonly run into miles of road that were stripped down overnight and there likely will be some sort of projection sticking out just where you didn't expect it.
At this ride height, it's just a 600hp +"freakin' Italian go-kart" now. Going lower is just going to seriously jeopardize the lower radiator support and as a result the radiator itself. I'm essentially at ground zero and the only thing I can think of is that my personal characterization by others as "Bat S hit Nuts Doug" has to be given the consideration as a likely accurate visualization?
The truth sometimes is painful. So is hitting a road obstruction.
The only thing lower that I have seen on the street was a Lola. In it you are virtually lying down driving it. If there was ever a vehicle too low to be safe on the street, it was that car. The stacks on the Webers are higher then the drivers head. It can easily change lanes by sliding right under the trailers on Semi's and forget about the vast majority of incompetents driving SUV's that were already over their heads with those vehicles before they even got out of bed.
You might seriously consider running roof running lights to give yourself a chance to be seen by other drivers on the street?
I may subliminally have a self image of Richard Branford but don't have those kinds of financial capability. All of this in a Pantera is a dangerous mix.
It's better to err on the side of conservancy for your own safety.
