What's the difference between the 2015 ford mustang shelby gt350 and the 350 r?

Seriously i have no clue

The GT 350R is more track focused. You can't get some of comfort and convenience features on it. That you can on the normal GT 350. Everything that comes in the GT 350 Track Pack is standard with the GT 350 R, plus you get carbon fiber wheels Pliot Cup 2 tires, a carbon fiber rear wing, a carbon fiber splitter, the rear seat is deleted as is the radio,.
