    Nils,
    I think you mean two-cam or four. Judging by the style of the wheels, I would guess this 275 is a two-cam "Shortnose."

    Joe, I've been distracted the past few weeks, so not been on here much. Do you still need ride heights for QV? If so, I'll measure my two tomorrow. Both are parked up on a flat floor, so I should be able to give you a decent reference point..

    Yes please Harry!

    We are planning on driving this week and will want to see where the ride-height settles at.

    As a Brit I just can't let this comment stand, though I will choose my words carefully in order to avoid any offence....I hope.

    The great British brand of Rolls Royce has a long and distinguished transition, which I appreciate may have gone through a number of changes to adapt to the modern world, however talking strictly in the traditions of Rolls Royce, I am not sure that the old fashioned British tradition of Rolls Royce would see a garishly coloured car, with a white interior and wood tonneau cover (in anything other than a pure wood such as oak etc) as in impeccable taste as is described above.

    As a Brit, maybe I am talking about the old world of Rolls Royce, which may be where the discrepancy in what is seen as impeccable taste may lie.

    Back to Countachs....

    as an alternative how about a custom foam filter (with flame trap) instead of the box lid.
    that should give the same feel of open trumpets (ie not a closed box) but with a decent bit of filtration included (which the mesh grills wont really give)

    example in the links below

    with filter (apologies that the angle is changed)

    The DD has forced intake of cool air and the shape of the airbox maximizes performance.

    Well, that wasn't as straightforward as I expected..

    First off, I checked tyre pressures on both cars, balancing them at 30psi front, 34psi rear. I then pushed the cars forward around a metre or so, to avoid any flat spots from being parked for a couple of weeks or so.
    To keep the measurements consistent, I measured from the very base of the sill (along the riveted edge), where the front and rear wheel arch extension intersects the sill edge. Here's what I found:

    12165
    LF 118mm
    RF 124mm
    LR 133mm
    RR 124mm

    12132
    LF 130mm
    RF 130mm
    LR 133mm
    RR 134mm

    So I now think the ride height on my car needs checking out, as it's not balanced left to right, or front to back. Then while the numbers for 12132 appear to be okay, visually, 12132 looks too high at the front to me.

    Joe, I hope these numbers are of some help to you, just wish they had been more even car to car..

    Thank you for doing this Harry!

    All data-points are valuable, we have to sift through and interpret them correctly.

    BTW, one variable to consider is, 90% of all sills I have seen are no longer horizontal with the ground having been somewhat buckled by inappropriate jacking. This will mean the reading for that area will be in error. Please consider this before you worry that the car itself itself is not perfectly horizontal.

    See the brand new Downdraft below with perfectly straight sill-seams that are horizontal with the ground, per the factory diagram. We ensured we met this standard with our car.

    Bearing in mind the hand-built nature of our cars, another consideration is going to be, is the body affixed to the chassis precisely the same on both sides?

    To determine this we'll add other measurement data points.

    Basically, we want it going down the road as horizontal as can be at the correct ride-height.

    More to come on this topic.

    Maybe it would be better to check the height of the tubular chassis to the road surface but not very easy to access. As 12132 measurements were so consistent, I'd suggest the bottom of the sill is a reasonably good reference point to work from.

    My car's sills appear undamaged from jacking, the only difference I spotted between them was 12132 had many more rivets along the bottom edge of the sill than 12165. I wonder which one is as it was done at the factory?

    I have the answer to that:

    Your HLA12165 is factory original.

    HLA12132 at one time sported aftermarket side-skirts, and during the rectification process back to standard, the sills were repaired, using more rivets.

    Interesting info, thank you.

    Looked back at the dimension graphics you posted earlier, regarding this issue of ride height. Shame they don't include a side-on diagram but then all the dimensions seem to relate to the height of lights etc, rather than to chassis height. Original sill height must exist somewhere..
