Effectively, the best postion, is when the servo link is perpendcular to the horn at dead centre. Usually as the links are at an angle (ie not perfectly horizontal), you need a little bit of angle in the horn to get the 90degree angle for the same steering throw each side.
Quick pick of what I mean... on my evo 5 the steering link is quite angled (high horn, very low steering rack) so the horn is quite a way off centre to get the perpendicular angle. However, this does give equal steering throw.
great tips! never notice that before...
