installed my streetunit mount today.http://www.streetunit.com/MAZDASPEED..._p/sum3amm.htm
got it with a "street" urethane bushing.
install was a breeze all tho i installed it upside down as it fit easier that way, i realize its going to cost me some strength with the way its designed but i think it will be fine.
shifts are smoother for sure,i have to give it more gas when taking off than i have been used to as it vibrated allot otherwise.
it does not vibrate at idle.
