The Grand American Road Racing Association has revealed that Hoosier will join Goodyear and Dunlop as an official tyre supplier to the Rolex Sports Car Series in 2004.

Hoosier will supply tyres for the new SGS class that currently competes as Grand Sport I in the Grand-Am Cup Series. Goodyear will remain the supplier for the Daytona Prototypes, while Dunlop will continue supplying tyres to the GT class that is expanding for 2004 with the inclusion of the GTS class and new GT specs.

"With the restructuring we are doing for 2004, the Grand-Am Cup Series is being reduced from four classes to two classes," director of competition Mark Raffauf said, "As the contracted supplier to that series, we are keeping Hoosier as the supplier for the SGS class to honour the existing contract."

Raffauf added that tyre agreements with all three companies extend through the end of the 2004 season.

Hoosier Tyre has announced that the tyre for the new class will be designated as 'SGS' and will be the only tyre legal for competition. This model is an evolution of the Grand-Am Cup tyre currently in use, and will be produced as a racing slick incorporating several refinements to improve performance without sacrificing the wear and consistency that the 'GAC' tyre has provided.

"We have looked very closely at the things that worked in Grand-Am Cup," said Hoosier product manager Mike Kraemer, "We knew that the GAC tire was well suited for the Cup series, and we wanted to make sure we kept the excellent qualities and, at the same time, increase the performance potential for the teams that move into the Rolex series.

"We could have started from scratch and built an 'all out' performance radial slick, and will continue working in that direction for other markets, but, in the long run, that would not have been in the best interest for the series. It is harder to get consistency rather than pure speed out of a racing tyre. We have a successful product in the GAC tyre, so we elected to use that as the platform for the new tyre. This evolution will reduce the need for extensive testing and chassis development as well."
