The following are some excellent Mario Kart shortcuts. Note: Reverse directions if playing on mirror tracks:
Maple Treeway Between the starting line and the first corner, veer to the right. You will see a dirt path in a gap in the fence. Drive through here to find boost pads and some boxes. This shortcut drops you out right at the warp jump point.
Mushroom Gorge This shortcut definitely requires at least one mushroom boost. From the starting line, lean left until you see a red mushroom in the distance. Aim for it and, just as you are about to go off the track, hit the boost. You should land in the middle of a red mushroom hidden below the track which will bounce you on to the next one and then bounce you back onto the boardwalk.
Wario's Goldmine During the section where you have to evade minecarts, stick to the left. Follow the last minecart. You will notice that it is lifted off the track-- aim to drive under it and you will land on a passage way with boost pads and boxes. this will let you out near the finish line.
Daisy Circuit Between the first two corners and the roundabouts you will see a flight of stairs. Best to boost up these, but driving normally works fine. This will lead to a box and a boost pad with a jump. You should land at the second roundabout.
Use the following tip to get more or less distance in the air after any big cannon or ramp, such as on DK or Maple Treeway. Use the Wiimote to do a wheelie for distance or lean the Wiimote forward to fall down sooner. For other controllers, press Down on the ANALOG STICK for distance while press forward for less air.
After the ramp leading into the fast moving stream, enter the little arch with the ramp on the left by using a super mushroom, invincibility star, or golden mushroom. Pass through the grass behind the giant red hat.
When playing with two or more players, draft by following a friend right behind them. Once you boost ahead, go around your friend and get in front of them. Now have them draft and get in front of you. Keep repeating this and you’ll both finish the race quicker.

To use the same character with two players, have player 1 select the desired character, then deselect it and move off it. Have player 2 select the character. Go back one screen, then re-enter the character selection screen. Both players will be on that character. Have both players select the character. This also works with three and four characters.
After getting a Triple Shell from an item box, press 2 so that all three shells spin around you. Instead of launching them, ram into other cars. They will inflict the same damage as if you had launched them at a target.
The requirements below will help you get a one, two, or three star rank. -Get a final score of 53 or above. -Lead most of the laps. -Stay in first place for a good period of time. -Do a lot of tricks on ramps. -Avoid having to use Bullet Bills to catch up. -Use lots of techniques such as wheelies, avoiding POW blocks, etc. -Do not fall off edges too much (one or two times is acceptable). If you get hit by many -Spiny Shells and still win, this indicates that you are resistant and will probably have a high rank.
Add a star icon next to your name on the results screen and online races by completing all the Grand Prix races with a specific rank. Unlock the listed star icon by performing the corresponding task:
STAR ICON - HOW TO UNLOCK One star profile name - Earn a "One Star" rank in all Grand Prix races. Two star profile name - Earn a "Two Star" rank in all Grand Prix races. Three star profile name - Earn a "Three Star" rank in all Grand Prix races.
Your rank goes up as long as points are added to your total score. Fore example, if you less than 3rd or fourth place in an online race, it can still be considered a win. Same goes for Battle Online. Your team can lose, but if you scored enough coins or hits then it adds points to your score and can be a win.
Drive through one of the many leaf piles to get a super mushroom or banana peel. When you reach the top of the tree with the caterpillars, an invincibility star can occasionally be found in one of the bushes on the left side.
Immediately upon starting Grumble Volcano, don't speed boost. Instead, reverse until you fall. Don't take the ramp you get put at just yet! Look left, you'll see a big rock. Jump near the rock and keep going in circles counter clockwise (Left). Keep repeating it until you get to the third lap, then go around the rock and go to the finish line at the end.
To get a boost at the start of a race, wait until "2" begins to disappear during the countdown, then hold "A". Then, right when the race starts hold 1 + A. When it says "Go" release 1 and A, and press A as you would normally to accelerate.
On the final lap of the Delfino course in the Banana Cup, a Blue Shell will always hit you on the bridge. This also happens when you’re close to the finish line almost every time you play this course. Thus the Blue Shell is “set” to hit.

While on a long straight road, get directly behind another racer. Continue to drive straight and you will see several blue streaks fly behind you and a blue force field in front. You will get a small boost.
When hitting half pipes (part of the track with white arrows and blue strips), hit them narrowly to glide through them. Tricks may slow you down slightly but you will get a boost when you come down either way. don’t hit them at about an 80 degree angle or else you won’t go over the top. Instead you’ll bounce up and down. Note: This tip isn’t recommended on Rainbow Road.
