Oli, basically the splitter shape was copied from another splitter which is ment for 951, not so demanding after all. After that i have changed shape a bit, to get it fit better. Splitter in the picture is not ready yet, it lacks mounting holes and some other cuttings which were made after i took the picture. Most of fiberglass jobs are more or less copying another peoples work or copies from oem metal parts. Most of us are able to do glassfibre parts after practising.
Making parts from oem metal parts are really easy; here's 911 bumpers i have made
