In the Instruction Manual, to the left of page 21 for ARS, it says to the refer to the HUDY Setup Book for more information on Active Toe-in. Has anyone seen this book or know where to find it? Likewise, this pointer has been referenced in the manual for roll-center, and others, etc., for the T4'13, T4'14, and continued now in the T4'15 Instruction Manual but I have yet to find any Setup Book with the T4 reference design changes. I can only find the T3 Setup Book. Of course, it is easy for previous T3 historical owners to understand the changes but new comers will not understand some of the differences. In all, I suggest an updated T4 Setup Book be published for configuration understanding with the latest changes. Anyone out there petitioning with me???
