March 20, 2007—Torrance, California USA – For the second year in a row, a StopTech Balanced Brake Upgrade®-equipped car led the SPEED World Challenge Touring Car race from pole position to the checkered flag on Friday, March 16. Jeff Altenburg, in his blue and white No. 72 Mazdaspeed Motorsports Development Mazda 6, was challenged for the lead only by teammate and 2006 SPEED World Challenge Touring Car Driver’s Championship runner-up Randy Pobst, in the No. 73 car. Pobst qualified and finished second, holding off a serious bid for the middle step of the podium from series champion Pierre Kleinubing in his Certified Pre-owned Acura/RealTime Acura TSX on lap eight. The Touring Car race went 18 laps with no yellows.

“It feels awesome to win and it was a perfect weekend,” Altenburg said. “First pole in four years and that was with the help of Randy [Pobst]. We decided we were going to help each other out more in qualifying and give one another a pull down the straights. We both got a clean start. Worked together to not do anything silly. Randy says he wanted to win with all of his heart and I’m sure he did, but I think he could have pulled a move or two during the race.”

Altenburg added, “The guys just did a great job for me this weekend. Ron (Carroll) and Brett (Monetti) worked together and gave me a really good car. I also have to thank StopTech for their brakes that helped me in every aspect of the race.”

StopTech also supplied its Balanced Brake Systems to the biodiesel-powered No. 24 A Mother’s Arms/Austin Hatcher Volkswagen Jetta TDI of Jim Osborn. Billed as the world’s first biodiesel-powered professional road race car, it unfortunately retired with mechanical issues in this, its first race.

Repeat Victory for StopTech

The winning performance in 2006 was turned in by Bill Auberlen, driving the Turner Motorsport/H&R Springs BMW 325i. Six days later, the E46-chassis BMW 325i received several competition adjustments, reducing its potential. Turner Motorsport chose to focus on a competing road racing series for the rest of the season, where it won championships in both classes.

This SPEED Touring Car race will be broadcast on SPEED Sunday, March 25 at 1:30 p.m. EDT.

Round Two of the SPEED Touring Car Championship will take place May 17-19 at Miller Motorsports Park in Tooele, Utah.

Grand Touring Class

In SPEED World Challenge Grand Touring, the 2007 Sebring event was dominated by Corvettes. The StopTech-equipped duo of Doug Peterson in the No. 87 3-Dimensional Services/LG Motorsports car and team owner Lou Gigliotti in his hot rod-flamed No. 28 LG Pro Long Tube Headers Corvette were impressive in practice and qualified first and third, separated by Eric Curran in Whelen Engineering’s new No. 30 C6 Corvette.

With a track still unevenly wet from earlier showers, Eric Curran, a rain specialist from his home track of Lime Rock Park, built up a strong lead early in the race. Gigliotti, while fast, retired with a mechanical failure on lap five. Peterson suffered an electrical glitch and lost three laps in the pits, but was able to finish the race. After a restart on lap 14, Curran and series champion Lawson Aschenbach, who switched from a Porsche to an XM/Mobil 1/ Motorola/Bose Cadillac CTS-V for 2007, held their positions at the front. Tomy Drissi, driving the LG Motorsports-prepped, StopTech brake-equipped No. 15 “Next – The Movie” Chevrolet Corvette was able to get past Michael Galati three laps from the end for a spot on the podium, his first in the series.

This SPEED GT race will be broadcast on SPEED, Sunday March 25, at 2:30 p.m. EDT.

Round Two of the SPEED GT Championship heads to the Toyota Grand Prix of Long Beach April 13-15.
