Now that's movin! Great job building a truck like that that you can still drive on the street.

A front bumper should help keep the front end from lifting at speed. Also, consider fender vents to evacuate some underhood pressure which also causes lift. If you don't want to cut the fenders, cut the hood...back by the windshield but on the outer edges. If this wasn't a street car your best bet would be a 1 piece, solid front end with an a/w intercooler in the bed. I'd grab a sheet of plywood to make a 1 piece tonneau cover and pro-stock spoiler. Use the template feature on this site to see how far off the back the spoiler should reach. Pro-stock spoilers usually have "fences" on the sides which kind of channel the air flow and help to keep the vehicle going straight. It's a nice truck I wouldn't blame you for not wanting to ruin the lines or the body with speed holes or big wings off the back. I think you'll notice a big benefit by fitting it with a larger front bumber/air dam.

Are all 4 wheels given 100% of the power? Or is it biased to the front or rear?
