Good carpeting comes with edging and, at door openings, a strip of vinyl. The vinyl glues up and over the edge of the door opening. However, this is a Lotus. So, maybe that will work, maybe that will prove too thick and then the door won't close, or too thin and you'll have to bolster it further to get it to seal. One thing I do know is that you fit the door FIRST, then fit the door seal. Shim, trim, support and/or cut back as required to get a good seal.
On my S1, the door seal was too thick. I had to trim inside the seal's u-channel and then it fit perfectly.
