Ah...slightly errant start on this thread.

I grabbed deQuincey's graphic which did a great job of identifying the clearances on his coupe.

And....although there was a similar thread on ground plane to trim line, it posed too many variables..tire / rim size, air pressure etc. etc.

So...this was to be a reference point for a new thread which used the centerline of wheel to underside of wheel arch lid for lowering height comparison which should be more consistent and reduce the variables.

I am 90% thru an install of Hardy and Beck's lowering kit which includes their springs and specially valved Bilsteins (to the extent the rear shock is actually adapted from a 2002).

Much like the discussion on the CN springs, the amount of drop is not quite what was anticipated, so for a better understanding I am interested in reference points.

After the install the H&B setup looks as follows, all centerline of wheel to underside of lip:

LF = 14.5" / 368mm
LR = 13.5" / 343mm
RF 14.75" / 374mm
RR 13.625 / 374mm

The front does not have a camber adjustment plate (potential nominal additional height) and the rear uses the one dot perch rubber.

Now H&B says their set-up results in a 1 - 1 1/2" drop. For comparison these are the measurements on 40+ year old springs on the car before the install.

LF = 14.75" / 375mm
LR = 13.75" / 349mm
RF 15.00" / 380mm
RR 13.375 / 340mm

Have to expect sag over 40 years, how much? difficult to say, but would expect a lower stance.

Be interested in resurecting this data baseline information. Who knows it might inform future spring production getting us closer to where that visual sweet spot is.

Thanks

That settled in nicely..
Can we get a measurement from ground to floor at the front behind wheel and at rear in front of wheel please?

Nein!

DQ's picture was taken with the car parked at a slope, resulting in larger gaps because the compression force is reduced. If the wall behind the car is horizontal the car is parked at a 4 degree slope I say. If the wall is not horizontal the Spanish taxpayers were shortchanged.

This is precisely why the windshield washer reservoir is translucent. One must see if the fluid is horizontal in the reservoir before making suspension measurements.

With me here who needs a mother in law.
