Just build it strong . . . /Robert With the rev limit top speed is just over 170mph. I'll have a play about and see what I can come up with. As it is at the moment I rely on the undertray to provide a touch of downforce but mainly to smooth airflow under the car and avoid areas of high pressure. What I might try and do is shape the front and rear sections of the undertray to increase airspeed and combat boundary layer formation. Don't know if it'll work as planned but I'll have a bloody good go LOL. As its not got to corner at these speeds downforce creation is not a concern minimising drag and lift is. Cheers Matt
