Yah. A bunch of peeps in the Mario Kart League are rockin' the 3 stars.
Nice choice - I use Peach with the Mach Bike as well (online matches), though I can't remember if I used her to pick the 3 stars up. She's probably fine, it may take a lot of practice, but once you're good enough it's possible to get 3 stars pretty consistently. Taken from here (click link for more details):
Here's a summary on how to get a 3-Star Rank:
To get a 3-star Rank:
Get 1st place in all 4 races.
Finish the race as fast as possible.
Stay in the lead for as long as possible.
Don't go off-track unless you are using star, mushroom, bullet pill, or Boo(ghost).
Don't fall off the track.
Don't hit the wall or course obstacles.
As for actual racing tips, take advantage of wheelies (especially after a drift boost). Try not to do anything risky for small gains (avoid making mistakes). Also, uh...
Yeah. No clue what else to say, dunno if that helps...
Good luck~
