Just had new trumpets installed. The front suspension is now sitting about 1.5-2 in higher than rear.
I'm told the trumpets require a break-in period in order to 'relax' and the suspension to take on its
final 'set'. I've seen other posts implying this. Question is ...... how many miles and/or time does it
take for the front end to drop to the lower height. Right now the front end height is about 1.5 in over
spec, i.e. wheel centerline to wheelwell opening. Thanks.

Your rubber doughnuts/cones are the 'springs' which sit on the trumpets up front should settle relatively quickly. Drive the Mini about. Normal road use & braking will aid the settling.

Question do you have new rubber at rear as well as the front? Are the front rubber doughnuts/cones marked with 4 Red Dots? Do new rear items have 3 Green Dots?

I ask because I installed new 4 Red Dot cones up front and new 3 Green Dot cones at the rear of my Mini Van, loaded it up to drive from British Columbia to Ohio. Fortunately, I have adjustable trumpets. The Red Dot cones did not require any adjustments but the Greed Dot cones in the rear required two stops to increase the length of the rear trumpets to get the rear at proper ride height. Before returning from Mini Meet in Wisconsin, I gave every thing that I did not need for the trip west to a friend who was headed west in a Subaru.
