I would be much more concerned with bump-steer for drag-racing.
Just watch some U-tubers coming off the line, to see some radical toe-change as the front ride-height changes. Scary stuff.
I wonder if the stock lower BJs with integral steering arms would be the best choice for front steer. I cant see it working very well for Ackerman or bump-steer; but then I suppose a drag-car isn't overly concerned with turning. Still, if the car gets sideways at half-track or speed, I imagine you would want the car to steer at least somewhat predictably!
Good luck in your engineering.
