I just installed a Street unit rear engine mount.
My opinion is that this upgrade really makes a difference.
1- when shifting from 1st to second I don't feel the engine 'jumping' anymore. the shifting is smooth.
2- when I downshift it doesn't fell too abrut (as with the stock enginge mount).
3-vibration is a litle bit higher (30% more) but not unconfortable.
4- the installation required the help of a mechanic (or at least somebody with a jack to lift the car and be able to fit between the car an the floor.
conclusion:
this is a good and recommended upgrade.
