[Overdriven]

Good looking truck! I know you said the bumpsteer isn't that bad, but you might be able to reduce it some. If you buy the "Hollow Ball" kit for the Revo (part #5355X) you can adjust the height of the rod end of the tie rod in the steering knuckle. It looks like you have the rod end in the center right now, I'd try lowering it so its parallel with the lower arm.

You must get a pretty big increase in camber as the suspension compresses too. Is there any way to raise the upper arm mount at all? If you could, it would definitely help with your bumpsteer issue as the rising camber is the main cause of it.
