So I searched "ride height" and got over 1000 topics, so after the 400th or so post I read I gave up looking. I'd like to know the height difference between the front and the rear on a mini with standard trumpets so I can adjust my HiLo's accordingly. Every stock mini I've looked at in pictures appears to sit higher in the back but by how much?

I have HiLo's fitted to my Mini on 13 inch wheels and have front and rear set the same. Is this incorrect?

Standard alloy trumpet lengths
front trumpet height as standard is 3.750" and the rear is 12.375" on the latest post 1979. The earlier ones were around 12.125". Dimensions from the knuckle end to the rubber cone seating face.
And yes standard the rear ride height is higher than front.

Mine are set to:  (in mm measured from the sill trim to the floor)

Front Height 220ns 220os 

Rear Height 240ns 240os

 

I'm using standard cones and Hi-Lo's all round.

I actually measured the original trumpets and set my Hi-Lo's accordingly but the cones settled a little different on each corner. So I wanted to get an idea of the measured height difference, from what maccers states it looks to be around 1" higher in the back.

None of those dimensions relate to the ride height, they are body dimensions for checking for accident damage at a BMC workshop. The heights relate to a fixed datum point rather than the road, which is used specifically to eliminate ride height from the measurements to make it more accurate.
