The Rolling Thunder tour finishes at Vodafone Speedway Western Springs on Saturday night but organisers are promising an expanded series next summer.
The concept has seen sprint cars, midgets and super saloons visit Palmerston North, Mt Maunganui and now Auckland over the last three weekends but promoter Greg Mosen thinks the success of this year will see it grown to more rounds next summer. "I think the series in its inaugural year has been a good start for us all," Mosen told the Herald.
"The racing has been amazing. The passing and the tracks, everything has been A-okay.
"Next year it will probably balloon out to five rounds so it has been a real success.
"It has just been an extension of what we have learned at Western Springs for the last few years from having it at home.
