the full 2005 NASCAR West Series after Childress offered her a contract to drive for Bill McNally Racing. She signed a three-year contract with RCR when Childress offered it to her with full financial support from Chevrolet, and planned to compete in the Busch East Series and the ARCA Re/Max Series in 2006. To prepare for the season, Fisher acquainted herself with the heavier, less-powerful stock cars, which she found difficult to control. She declined offers to race in the 2005 Indianapolis 500 so she could keep a promise that she made to Childress and NASCAR president Mike Helton to refrain from doing Double Duty, and wanting to avoid sending a message that she was not committed to NASCAR. She began the season with a 20th-place finish in the United Rentals 100 at Phoenix. Three races later, Fisher had her first lead-lap finish, coming in 12th in the Autozone Twin Championships before earning her first top-ten result, an eighth in the King Taco 150 at Irwindale Speedway. She qualified a season-high third in the Coors Light 200 at Evergreen Speedway; Fisher led the first laps for a woman in NASCAR West Series history, finishing 11th.

Fisher secured the seat by staying in contact with the team through her engagement with tire changer Andy O'Gara, as well as attending several IndyCar races throughout 2006. Additionally, the team contacted prospective sponsors requesting sufficient funding for her participation in place of Ryan Briscoe, who had Supercars commitments. Fisher finished in her starting position of 12th after car setup problems. Her performance in this race led Dreyer & Reinbold to hire her for the season-ending Peak Antifreeze Indy 300 at Chicagoland Speedway. Fisher ended the event in 16th, giving her a two-race
