You do the same thing on the suspension wires as on any old roundhouse kit, run the string through and tie it off and tape down.

When assembling, please note:

• Heat the trucks before inserting the wheels if they're cold.
• If you use off the shelf trucks you need to make your own screw holes and whatnot, but they work great still.
• The shells can just be hot glued to the chassis, it works and is durable.
• Everything needed for the couplers is included exept attachment (screws, toothpicks, glue, what have you)
• You can use screws, but cutting toothpicks to size, inserting, and pushing them in with pliers works great
• I recommend kaydee 148s or some similar variety, but most couplers work.
• Use whatever 33 inch wheels you prefer, but I recommend metal ones, preferably intermountain
