The Record Setter is a High-End glider in Mario Kart Tour that debuted in the Sky Tour. The glider consists of a digital meter with rainbow wings on both sides. The glider is unique in the fact that the meter measures the distance traveled by the user while they are gliding, similarly to the gliding meter seen during Glider Challenges. The meter can reach a maximum distance of 999.0 before stopping.[1] The Record Setter improves the chances of rolling Mushrooms from Item Boxes and increases the number of points earned for using Mushrooms. It is the only item to gain two new favorite courses after being upgraded to level 8.
