100% serious. The DC5/EP3 toes in with bump travel from the factory, and moving the inner end of the tie rods upwards will only make this issue worse. For example, Realtime Racing, that once ran what were probably the most well prepared DC5s in the world, lower the inner end of the tie rod to correct this (probably in combination with a custom outer tie rod end):

Correcting bump steer is not a one size fits all solution, you need adjustment and it needs to be tailored to your ride height and geometry.
