Braun Racing has named Trip Bruce as interim crew chief for its No. 38 NASCAR Nationwide Series team and driver Jason Leffler, effective for the next three races.
Bruce replaces Scott Zipadelli, who joined the team for the 2009 season.
Leffler will actually be driving Braun's No. 10 Toyota in this weekend's race at Darlington Raceway, but the No. 38 team moves to the No. 10 entry whenever Leffler drives it. Kasey Kahne is in the No. 38 for Darlington, with his regular crew chief, Stewart Cooper, moving with him.
Bruce will serve as Leffler's crew chief for Darlington, Dover and Charlotte.
"We felt it was necessary to make some changes on the No. 38 team as performance has struggled this season," team owner Todd Braun said. "We are looking for a spark to ignite the team and improve their on-track performance. We have been through a lot of good races with Jason and I feel like this is a better team than results have shown."
Leffler finished fourth in the 2009 Nationwide standings, with eight top-five and 20 top-10 finishes. But he's only 15th this year, with one top-10.
