I can't be 100% sure. The torque steer problem was, as far as I heard from people who likely weren't being very charitable about it, a geometry stuff up when the track was widened from the standard C170. The guy doing the design apparently held the scrub radius fixed, instead of the king pin offset. I'm not a chassis guy myself, but the kinematics of such a suggestion makes sense, although I'm sure there's always a compromise to be reached in all of this.
