NASCAR heads to Kentucky Speedway for Saturday night racing for the Quaker State 400.

FOX's Marghiee Teshineh has "FOX in the Fast Lane":

The Sprint Cup Series races this weekend at Kentucky Speedway where the mile and a half track just completed a series of upgrades including a repave which for driver Aric Almirola means:

(Almirola) "The Kentucky as we know it, is long gone and this is a 'new' Kentucky and driving style and habits that we have now will have to be formed for this new race track."

Kyle Busch, who won last year's race on the old surface said:

(Busch) "This is certainly one of those places that we all didn't want to see repaved."

But Busch admits the changes were necessary because when it rained at Kentucky:

(Busch) "The weepers were just so bad that we could never get it dry enough. I mean the race track was dry, but it was still weeping water, hours later, days later."

And Tony Stewart was at Indianapolis Motor Speedway this week, to run a few laps on a new dirt track created at the infield by officials as a gift to Stewart who retires at the end of the season.
