LOL....Ford land aye!.....yup because I would never own a Holden! Six of one half a dozen of the other....there both pieces of Shit!
pixlel8r as previously stated....it's personal preference! Mine preference is is pull back to shift up.....thats how my old Drag car used to work, so it's habit to me now.
Also I am not sure about the greatness of G force in acceleration with these things but I will tell you....under heavy braking I would much prefer to be pushing forward to shift down than pulling back....again my personal preference.
