Pro Stock Car: Which track is the most difficult?

The NHRA will visit their last stop on the Western Swing schedule this weekend. Listening to Dave Reiff and Mike Dunn talk in Denver about how difficult Bandimere Speedway is for all categories, it made me wonder...which track is most difficult on the NHRA circuit?

I recently took to Twitter and asked Vincent Nobile, driver of the Mountain View Tire/NAPA Auto Parts Pro Stock Car, which track is the most difficult for the Pro Stock Car category.

I thought Vincent might choose one of NHRA's bumpier tracks, like Wild Horse Motorsports Park (formerly Firebird International Raceway) in Phoenix, Arizona or Thunder Valley in Bristol, Tennessee, because it is rough on the cars.

I was wrong!

"Definitely Denver," said Nobile. He said it is because of the "drastic elevation change."

The elevation of Bandimere Speedway is 5,800 feet above sea level, meaning the air is much thinner than it is at other tracks. The thin air causes the cars to lose down force, which makes them run slower.

Because of this, Nobile said that Denver "calls for a totally different setup than what we normally use."

Allen Johnson took home the trophy on Sunday, Jul. 21 at the Mopar Mile-High Nationals in Denver at Bandimere Speedway, but Vincent was victorious in Sonoma.
