it's good no matter what, even if you go duals later you still have your twin sticks
There are two types of twin sticks for Toyota. One is for forward shift, and one is for top shift. So, if you get one for a forward shift now, and go duals later, then you will need to get the other. But if you have a top shift now, and get one, then later you will have the right one. The bases have different bolt patterns.
