Get the base bushing and the shifter cable bushings I don't know about a smoother shift, but my one is damn solid. I'm using TRD SS + shifter cable bushings. With the TWM, you will have to try and remove the round clip off your existing cradle which is a bit of pain. If you happen to destroy it in the process, have a browse through bunnings as they have some in stock, but not sure about the size. If their is one thing I don't like it would definitely be the istallation, I kinda butchered mine one. The TWM will give you a shorter throw compared to the TRD SS but you will want a heavy gear knob to help with the shifting, if not then you'll be looking at sore forearms :(
