Boost starts are a great way to get a head start in Mario Kart Wii. By performing a boost start, you can gain a significant advantage over your opponents and increase your chances of winning the race. There are several factors involved in performing a successful boost start in Mario Kart Wii including: timing, button sequence, and vehicle selection.
To perform a boost start, you must first press the gas button just as the starting lights turn green. This will cause your vehicle to start moving forward. As soon as your vehicle starts moving, you must then press the A button to initiate a wheelie. If you perform this sequence correctly, your vehicle will get a significant boost of speed, giving you an edge over your opponents.
