You will need a front diffuser/splitter to help keep the air from going underneath & producing lift.

Oh, it would most definately be needed. Im going to drop my truck about 4-5 in the front and the rear will be dropped 6-7 and Im going to get one of the hd silverado lower valances and the tahoe front lip extension to help with airflow up front.

SC, have been out on the new section of 130 they just opened there is a big sweeping turn with a mile long stretch after the turn, you could hit the turn doing 90-100 and then stomp it, I bet you could wring it all the way out on that stretch.
