Bristol, Tenn. — The moment practice ended at Bristol Motor Speedway, Kurt Busch climbed the steep banking of the concrete bullring. He checked the track temperature in several spots, then used his shoes to test the grip of the surface as he scuffed his way back down.

There’s a sticky situation heading into today’s race in Thunder Valley, and it’s causing fits for the drivers.

“It’s tough to trust, it’s tough to predict,” said Busch, a five-time Bristol winner.

Bristol officials applied a VHT resin to the track surface that is intended to enhance grip. The TrackBite is much wider than it was last summer, when Bristol first tried it in August in an effort to make a stronger second lane. The top lane for years had been the preferred line, but the wider swath of VHT seems to have made the bottom of the track the place to be as drivers used limited practice time to prepare for today.

Intermittent rain at Bristol has wiped out a ton of the notes drivers have gathered about the surface because every time they think they’ve figured out a lane, the showers wash off any tire rubber that’s been accumulated. The Xfinity Series race was stopped for rain Saturday, hours after the Cup drivers had completed their final practice.

Every time on the track, the bottom lane is where everyone wants to be — all but current points leader Kyle Larson.

Larson, who starts on the pole because Friday qualifying was washed out, was among only a handful of drivers trying to run near the wall during practice. It almost bit him during Saturday morning’s session when he spun and clipped the outside wall. It caused only cosmetic damage to his car.

But, after running a chunk of practice on the bottom line, he went to work on the top and wondered why so few other drivers were willing to try to make it a two-lane track.

“I feel like it would still be really fast up there (in the top lane), it’s just nobody is brave enough to go up there and work in the groove,” Larson said.

“The VHT is wider than the width of our race cars now, too, which makes it extremely easy to run around the bottom.”

Should the top line fail to become appealing by race time, Bristol could revert to the way it once was — a one-lane track in which bumping a car out of the way was the only way to make a pass.

Jones Wins Second Straight Xfinity Race

Bristol, Tenn. — Erik Jones earned back-to-back Xfinity Series victories after a win Saturday at Bristol Motor Speedway.

Jones also won at Texas Motor Speedway on April 8. He was the defending race winner at Bristol from last year.

Jones won in a Toyota for Joe Gibbs Racing on Saturday, but he’s shown strong speed in his Furniture Row Racing car all weekend in preparation for the Cup race on Sunday.

Ryan Blaney finished second — the same result he’s had in all three Xfinity Series races he’s entered.

Daniel Suarez was third to give the JGR cars two spots in the top three. Xfinity Series leader Elliott Sadler was fourth.

Daniel Hemric won a $100,000 bonus from Xfinity as part of its Dash-4-Cash program. He finished fifth.
