RSR Racing is a former American racing team formed from the defunct Rocketsports Racing. In the spring of 2009, Paul Gentilozzi and his sons, Tony and John, founded RSR in partnership with Jaguar Cars Ltd. to build and race the Jaguar XKR in the American Le Mans Series GT2 class and to develop aftermarket performance parts for Jaguar cars in North America. In late 2015, RSR became involved in the Lexus GT programme. They will compete at the 2017 IMSA SportsCar Championship with two Lexus RC F GT3 under the brand 3GT Racing, with Scott Pruett and Sage Karam as two of the drivers.
