Mario Kart 7/Kart parts

The numbers here are comparisons to Mario sitting in the combination of Standard+Normal+Super Glider. For example, "Off-road: +1" means that this part combined with the other two specified above gives you one bar better off-road than the combination specified above, while "Off-road: 0" means that it's the same. The combination above gives you 3 1/2 bars of speed, 3 bars of acceleration, 3 1/4 bars of weight, 2 4/5 bars of handling and 3 3/4 bars of off-road. There are six bars to be filled in total.

Default Frames
This is the part that your character sits in.

Default Wheels
These have the biggest effect on your kart's stats.

Unlockable Frames
These are unlocked by getting a lot of coins. They are unlocked at random.

Unlockable Wheels
These are unlocked in the same way, although the Gold Wheels are unlocked by getting at least a one-star ranking in every cup.

Unlockable Gliders
Also unlocked with coins. By default, you only have the Super Glider. Every other glider has the exact same stats: Speed=0, Acceleration=+ 1/4, Weight=- 1/4, Handling=0 and Off-road=0. Thus, only the gliders' names are listed here:
 * Parafoil/Paraglider
 * Swoop/Swooper
 * Flower Glider
