1.Add a section of gym mat inside the pour bag in the butt area. Extra padding in the butt is necessary as the driver will tend to squish the foam away from that area when they eventually sit down.
2. Create a rope loop suspended from the ceiling for the driver to pull themselves up and away from the seat when you pour. This allows the foam to flow down around the butt area.
3. Push the foam mixture down toward the butt and thigh area. Gravity alone isn't quite enough to get the foam there.
4. Have the driver wear disposable painter coveralls with hood to protect from foam overflow
5. Box the entire cockpit rear and sides with cardboard. Leave no nooks for foam to expand into
6. Have the driver push shoulders aggressively backward (lean backward hard) when foam begins to expand. Otherwise the foam will push the driver forward into an upright seated position. You don't want that.
7. Be aggressive in trimming using the provided electric knife. But do it in small increments, each time putting the seat back into the car and having the driver test it. Eventually less is more so that you have room for shifting, etc. Don't cover the seat until you have raced in it at least once, as you will for sure want to make mods after racing.
