SELECT GT1 CARS TO RECEIVE PERFORMANCE ENHANCEMENT AT ROAD AMERICA, MOSPORT

ACEMCO Motorsports' Saleen S7R likely will mix it up more often with Corvette Racing's two C6-Rs in the next two ALMS rounds. Braselton, Ga. - In order to bring competitive balance to the GT1 class in the American Le Mans Series, the International Motor Sports Association (IMSA) has issued a bulletin allowing class cars that were homologated prior to Dec. 31, 2003 to run larger restrictors at the next two ALMS events.

It also calls for Corvette Racing's two Corvette C6-Rs to compete with an additional 25 kilograms (55 pounds) of ballast, in accordance with a bulletin issued by the Automobile Club de l'Ouest, the international sanctioning body for the ALMS, effective Aug. 10 through next year's running of the 24 Hours of Le Mans. It also applies to Aston Martin's DBR9 in any ACO-sanctioned event.

"We are extremely gratified by the wonderful level of competition among all our teams on technical issues and in terms for value for our fans and competitors," said Tim Mayer, COO of IMSA. "Corvette has always taken a leadership role."

IMSA's ruling, which is an extension of a previous bulletin issued July 1, will enhance the performance for multiple GT1 cars at the Generac 500 at Road America and the Grand Prix of Mosport: the No. 63 ACEMCO Motorsports Saleen S7R, the No. 5 Pacific Coast Motorsports Corvette C5-R and the No. 71 Carsport America Viper.

The improvements should allow for as much as 50 additional horsepower to the cars, according to Doug Robinson, IMSA executive director. The No. 35 Maserati MC12 has been running with a larger restrictor since the New England Grand Prix at Lime Rock Park in early July.

The No. 35 Maserati MC12 and the No. 5 Pacific Coast Motorsports Corvette C5-R will benefit from larger air restrictors allowed to older GT1 cars. Corvette Racing has finished 1-2 in the last five rounds of the ALMS. The ACEMCO Saleen, however, led more than 20 laps at Portland with a slightly larger restrictor in place. The hope is that leveling the playing field will provide fans with better racing and encourage privateers with older cars to join the series.

* IMSA also has announced that it will extend the eligibility of prototype race cars designed to 2003 standards through at least 2006. It will allow cars like the Audi R8 or Lola EX257 to continue competing in the series as new chassis become available. Robinson said the older cars could face penalties in weight, air restriction or other areas to encourage teams to purchase cars that meet the ACO's current class rules.

The Generac 500 at Road America, Round 7 of the 2005 ALMS, is set for 3 p.m. EDT Sunday at Road America in Elkhart Lake, Wis. The race will be broadcast on SPEED Channel. Qualifying is scheduled for 2:55 p.m. EDT Saturday. American Le Mans Radio, and Live Timing and Scoring will be available at www.americanlemans.com.
