While my info is dated, there was mention the #24 & #48 Teams are in the same building and share all the resources and equipment equally. Up to the point that the uniforms in the shop are generic.

Additionally , all four Hendrick cars share their set ups before and during the race. All the engines come from the single in-house shop.

For a " Spec " car, the #48 personnel including the Crew Chief have the ability to work as a Team at the track along with the driving skills of JJ. Notice the incidents this past Sunday where JJ lost track position during pit stops, but made up the difference on the track. When the lug nut came off during a pit stop , JJ lost 6 track positions, but was able to recover.

Tony Stewart credits the Team personnel for his success this year, even though he uses the chassis and engines from Hendrick.

Do not recall the details, but the #48 has been taken to the NASCAR R & D facility a number of times after races for very close scrutiny, Recently, NASCAR warned them they are very close to the spec with little room for error, but still legal. i,e, attention to the details.
