The reason of downforce need is wheel spin all track, i will leave a picture of an example of the pick up.

Here are some trucks which were modified for top speed stability,and legal for their racing class.All the mods are for stability at high speed.
All of these trucks have wheelspin issues right up to terminal velocity,and their mods help to keep them from going sideways.
These mods will cut drag as well as help with stability/downforce.
The NASCAR truck series also uses mods for high speed stability

From a safety standpoint,you should look at total downforce/lift issues with the truck.
*You have enough rear overhang that with too much rear downforce,the rear axle will act as a fulcrum,lifting the front of the truck at speed.
*Acceptable load at 85-mph,will see 8-X this load at 170-mph.
*I suspect that you'll have to balance the nose with a splitter,as mentioned already by members.
*Without a wind tunnel to develop your 'kit',you may want to bracket your runs,slowly building speed with each run,to make sure you haven't over-designed the rear.You don't want to pop a wheelie at 170-mph
