I sold my mp9e to get the cobra be 2.0 because I liked the layout. I built it to spec as per book , you drop the car on the table from 5 inches and the chassis slaps the table. I went to 40wt oil same thing. I ordered 8 hole pistons and went to 45 wt same thing. does anyone know whats going on with this. I feel it should work as default from book but this wouldn't work in the yard. please advise before I list it on ebay , thanks Rick frustrated
