Nip/Tuck:
Lower diffuser insert:
Mockup:
Keen eyed amongst you will notice some slight changes in the lower rear later on. With such a radical cut and fab, we started in one direction and then changed slightly as we saw it, stared at it ...stared some more... tweaked here...moved a piece there. Just part of the process. Cardboard, tape and bent tig rod curves work well for us up to a point. When it comes to much larger areas involving multiple surfaces, planes, converging shapes etc, sometimes a two steps forward, one step back approach is needed...
Underside with central insert mocked up and vented 'closeouts'. We also transitioned the lower rear quarters by removing the pinchwelds and making a new smooth transition to meet up with the rear diffuser area in the same plane.
