This is an evolution of my first design. The mounting system using threaded inserts and using a tall block of plastic instead of individual standoffs is much improved and the splitter mounts rigidly to the car. I wanted to increase front downforce so I added the two diffuser elements into the splitter. First drive after installing it and measuring tire temps at the end, the front tire temp is now equal to the rear temps when previously the fronts were typically a few degrees cooler. I can also crank the rear wing angle without it making the front feel light. My reasons for doing this are to try and create a high downforce car that can go fast but also turn well. If you are purely speed running maybe not for you but having a car that doesn't lift off at high speeds seems like it would be good too. I printed with 3 walls in Esun black high speed upgraded petg at 238c nozzle and 81c bed in the orientation the files are saved in. Also with supports everywhere on where needed. For assembly of the pieces I use ca glue to glue the aligning plugs and the 3 main splitter pieces together as well as gluing the triangular mounting block to the splitter. Install threaded inserts prior to gluing it to the splitter. The inserts are for m3 and work with the stock screws. Also ca glue the ring the holds the body to the groove on the splitter top. I had to reverse the screw that holds the light bucket onto the bodyshell, placing the nut on the outside of the shell. This allows the shell to clear the diffuser piece of the splitter.
