Biffle still critical of Johnson test

Before the weekend started, the Roush Fenway driver had voiced his disagreement about Johnson being one of eight drivers who completed work for Goodyear last August, to help select the tyre specification that teams would race in the second event of the Chase.

Following the race, Biffle insisted that it was unfair on his Chase rivals for Johnson to get an advantage out of the test, as the reigning champion eventually translated that into the race weekend which he dominated by taking pole position and scoring maximum points.

Juan Pablo Montoya was also part of the test and he finished the race fourth after starting from the front row. AJ Allmendinger was another of those testing and he ran seventh at the flag, while the other five participants in the test didn't fare that well in the end.

Biffle, who was not part of the test, was never a contender for victory and his 13th place finish leaves him ninth in the Chase.

"It was a frustrating day," said Biffle. "What's probably most frustrating about the whole thing, and I hate to beat a dead horse, is that the 42 [Montoya] and the 48 [Johnson] and I don't know who else came up here and tyre tested, and when we came back, look at the guys that didn't tire test, we ran terrible.

"It was a completely different tyre, it had us off our game right when we unloaded off the truck, we couldn't even make a lap on the track. We got going there toward the end, but not like the guys that tested. That's the whole deal. We had a decent car, but we're not going to beat guys that came here and tested."

Johnson shrugged off Biffle's comments once again and he clarified that despite being involved in helping Goodyear finalize their tyre selection for the race weekend, he only tested the tyres they actually raced for a couple of runs back in August.

"At the end of the day, like I said in here before the weekend started, Goodyear notifies us as to what tracks we're to tyre test at," said Johnson. "They asked us to test, we came and did our jobs.

"It is beneficial to tyre test. I saw some comments from Montoya where he said it's not beneficial. To be honest with you, it does. To get the data set, and the driver being in the car helps.

"Nobody spent a lot of time on the tyre that we actually came back with. So at the end of the day, we're just doing what we're supposed to do. If it's upsetting guys and they're pissed, so be it. I'm glad they're worried about other things and not the race car."
