SCCA Pro Racing Announces SPEED GT Competition Adjustments
TOPEKA, Kan. (April 2, 2004) -- SCCA Pro Racing Ltd., organizer and sanctioning body of the SPEED World Challenge Championship, announced today several competition adjustments for its SPEED GT category cars.
The biggest changes affect the Cadillac CTS-V, which finished first and second in its debut at Sebring March 19. SCCA announced an adjusted base weight for the car, a different air restrictor, a lower rev limit, a weight distribution limit, the mandatory use of a Tremec synchromesh gearbox and a freeze on air intake assembly development.
"After reviewing the race tapes and data from Sebring, it was very clear that something needed to be done to bring the Cadillac CTS-V in line with the rest of the field," SCCA Pro Racing Vice President and General Manager Mitch Wright said. "The car was new to us, and its potential was clearly underestimated. Our goal is for any well-prepared car, run by an excellent team with excellent drivers, to compete for pole positions, podium finishes and race wins. Adjustments mid-season are not unprecedented, and we believe this adjustment to be necessary in order to maintain that parity at the front of the field."
When the Cadillac CTS-V next appears at an SCCA SPEED GT race, it will weigh 200 lbs more than Sebring, be restricted 30 percent more on air flow (to a total of 50 percent restriction), have a rev limit of 7000 rpm (900 rpm lower than Sebring) and be limited to a maximum of 49 percent rear weight distribution. The air intake Team Cadillac developed for Sebring will be the system specified on the car's Vehicle Technical Specifications (VTS) for the remainder of the season.
The car was permitted to run a dog-engagement gearbox for Sebring at a 100-lb penalty, with the stock gearbox required at subsequent races. This ruling has not changed.
Summary of Cadillac CTS-V changes: <pre> Sebring Lime Rock Net Change Base Weight 3000 3200 +200 lbs Alternate Gearbox +100 NA -100 lbs Air restrictor 80.5mm 63.6 mm -16.9mm (30%) Rev Limit 7900 rpm 7000 rpm -900 rpm Weight distribution max NA 49% rear Car ran this way at Sebring Mandatory Air Intake NA As specified by VTS Car ran this way at Sebring

The SCCA Pro Racing SPEED World Challenge next travels to Connecticut to headline the Mohegan Sun Grand Prix at Lime Rock Park, May 28-31. For more information about the SCCA SPEED World Challenge, please visit www.world-challenge.com.
