Chevrolet is offering a special options package this spring to Corvette buyers who want to wring just a bit more performance out of their cars--or take it onto the track--without having to step all the way up to the ZR1.

The Competition Sport Package will be available on the ’09 Corvette Coupe 1LT and Z06 models. The package includes gray-colored racing stripes, headlamps and wheels; a set of Corvette racing pedals; a special engine cover, and the Corvette Racing “Jake” logos on the B-pillar, seat headrest and center armrest.

On the 1LT coupe, the package also adds the Z51 performance package--bigger brakes, stiffer suspension, differential cooler and a limited-slip differential with a 2.73 axle ratio--along with the performance exhaust system.

Engine output on the 1LT coupe with the package is 436 hp, a 6-hp jump on the base car as a result of the performance exhaust system; on the Z06, it is unchanged at 505 hp.

Buyers also will get a set of racing-style numbers--based on build sequence--which they can install.

Pricing information is not yet available. The Corvette assembly plant in Bowling Green, Ky., is idled and scheduled to restart production on Feb. 15.
