Another key piece to 2018 that still needs to be announced is which teams will have the 36 guaranteed positions for each race. Those go to teams with NASCAR-issued charters.
The Furniture Row #77 team charter has been sold to JTG Daugherty Racing for its #37 car.
Among those teams that need a charter for 2018: #12-Team Penske (Blaney), #21-Wood Brothers Racing (Menard) and #72-TriStar Motorsports (Cole Whitt).
Teams that currently have extra charters for next year include Roush Fenway Racing (it gets back the one leased to JTG), Richard Petty Motorsports (it gets back the one leased to Go Fas Racing, which gets back the charter it leased to the Wood Brothers) and Front Row Motorsports (it gets back the one leased to TriStar). If RCR doesn’t field the #27 car, RCR also would have a charter available for lease or sale.
Teams are allowed to lease out a charter for one year but then must use it or sell it over a five-year period. There is no limit as far as how many years a team can lease a charter from various organizations to keep the guaranteed spot in the field, it just can’t be the same charter year-to-year.
