They should be happy this year so far with Daytona testing anyway.
Here's what Jr said last year during the race.
RADIO CHATTER: During the 10-minute break following the first 20-lap segment:
Dale Jr: "I'm outta control... this car is outta control. It's like there's no air on the car... I don't know what to tell ya- don't know what to expect with this car. It has no grip at all - sometimes I lose the front and sometimes the back. If somebody runs really tight on my right rear it's really bad. I don't like what we got here - I don't like the aero..."
Dale Jr. (as the entire field swerved to avoid safety trucks on the circuit during the slowdown lap): "Whoa. Is this where we do the 40-yard dash through the archery range?!"
Dale Jr. was unhappy with some of the maneuvers of his fellow drivers during the opening 20-lap segment:
"Damn, that's OK to drive that way goin for the win, but I don't know about that during a 20-lap segment. Some (idiot) holds you down low with only a foot or so to the apron... I'm gonna start knockin' some doors off here if they don't give me some room. When a car is on me like that, it's like I'm driving a sprint car through the tri-oval... I'm loose and hangin' on."
