[s-cars] subframe mounting hardware dimensions

[Sean Douglas]

Mike:

The first number is the diameter, second is the thread pitch and 3rd number
is the length. Remember that European nomenclature is that the comma in
Europe means a decimal in English.

Hence M12x1,5x105 means 12 mm diameter, 1.5 mm thread pitch and 105 mm in
length.

I'm not sure about the M12x1,5x150x60, but I think it means that it is
partially threaded, in other words its 150 mm in overall length, but only 60
mm of it is threaded.

I'm pretty sure the shorter ones are for the front and the longer ones are
for the rear. Now that I think about it, the partially thread ones are for
the rear, because they pass through the control arm. Also, don't forget to
buy new sleeves where they pass through the control arm, these are normally
damaged when removed.
