What are the effect to the steering when doing this modification?
It makes the car a lot more neutral off center and easier to drive. The stock steering location makes the steering feel aggressive off center then taper off towards the end of the throe, hence a digressive feel.

The other way to do the steering mod:
- Mark up and drill a 1.5mm pilot hole
- Drill out to 2.5mm
- Use a M3 tap
- 1mm spacer and a short ball stud
- No spacers on servo horn ball stud
