I don't race mod, sorry. I use a X12 17.5 in off road blinky - I use the 2 dot insert. I'm not sure what insert you would use for on road sedan. The trick with the X12 is to run the gearing & timing that keeps the motor under 80 - 85 degrees c max (180 - 185F). You can't run very much ESC timing due to the fact that 27.5 degrees of endbell timing is the lowest you can go.
