Veteran short-track racer Mario Gosselin of Lake Hamilton, Fla., topped the unofficial speed chart Tuesday night at Lowe¿s Motor Speedway as 16 ARCA RE/MAX Series teams made final preparations for the May 22 ADG 100 presented by EasyCare Vehicle Service Contracts.

Gosselin, winner of the 1999 ADG 100 and a two-time ARCA RE/MAX Series pole winner here, posted a lap of 29.94 seconds for an average speed of 180.360 mph around the 1.5-mile superspeedway in his No. 12.

Kyle Busch, the 17-year-old brother of NASCAR Winston Cup star Kurt Busch, was second quickest at 180.000 mph in a Hendrick Motorsports entry. Busch was on a simulated qualifying run late in the practice session when he spun in turn four, but did not make wall contact.

Clay Rogers was third fastest on the unofficial stopwatches at 178.690 mph with A.J. Henriksen (175.953) and Robby Benton (175.724) completing the top-five.

The only accident during the five-hour testing session came shortly after sunset when Roger Williams lost control in turn four and hit the inside retaining wall. Williams¿ car suffered heavy front-end damage, but he walked away uninjured.

The ADG 100 presented by EasyCare Vehicle Service Contracts will be run after NASCAR Winston Cup qualifying during CTC Pole Night on Thursday, May 22. Tickets are available online at or by calling 1-800-455-FANS.
