Hmm,

Would it be possible to go to a 'lower hole' on the base bracket to 'tighten up' the gap up front while keeping the same rake?

(Y'all might have to cut me some slack as I've only looked at 1-2 of the MadStad 'robo-bracket' downloads to get a general grasp of how they work. Quite sure there is more than 1 form of robo bracket.)
