1989 Chevrolet Corvette - Backup Plan

For The Chip Miller Family Collection, The Best Corvette Challenge Racer Was The Car That Never Raced

Racing is as much a part of Corvette DNA as the V-8 or the crossed-flags emblem. During the '80s, that was good news for Corvette, not so good for competitors who were becoming experts on Corvette taillights. In most every class, the only real race was between Corvettes up front and the back-of-the-packers dicing for leftovers. From the promoter's perspective, runaways demand correction as they are kryptonite to ticket sales. With the C4 on top of the racing world, the SCCA faced a situation.

"In the late '80s, Corvettes were dominating everything when they raced in SCCA," says Lance Miller, senior manager of Carlisle Events, and son of Carlisle's Chip Miller. "Lotus, Porsche, all the other competitors were complaining to the point that they threatened to pull out."

Office: All Challenge cars had rollbars and racing seats installed.

The solution came from John Powell, a journeyman racer, team owner, and organizer. Since the Corvettes were in a class by themselves anyway, John's proposal was to set up a separate class for Corvettes only, have Chevrolet build a special package, prep the cars for the top performance, and have them race for the largest purse ever seen at this level of racing.

Everybody seemed to like the idea. It relieved a big headache for SCCA, gave GM a high-profile venue to showcase its flagship sports car, offered a competitive triple-A series for up-and-coming drivers to demonstrate their talents, and provided sponsors with plenty of stylish, bright-colored bodywork to paste their decals on.

The inaugural season was 1988. Chevrolet came up with 56 identically built coupes, painted in any of seven colors, and spec'd out with the 245hp Cross-Fire 5.7 V-8. Chevrolet built the engines identically, but selected engines that were equivalent in output, sealed them up, and shipped them from the Flint engine plant to the Corvette plant in Bowling Green. Other equipment included:

* Doug Nash 4+3 manual transmission
* Z51 Performance Handling package
* AC3 Six-Way Power Driver Seat
* UU8 Delco-Bose Stereo
* Z6A Side Window and Side Mirror Defog
* 24S Blue-Tint Glass Removable Roof Panel

For this option package, Chevrolet issued the package code B9P.

Next stop for the Challenge cars was the Protofab shop in Wixom, Michigan, where they installed rollbars, racing seats, an on-board fire extinguisher, a set of Bilstein shocks, and four Dymag wheels. Six cars built for the Corvette Challenge did not receive this conversion.

Pricing was $33,043 for the B9P car, and an additional $15,000 for Protofab's additions.

Exxon signed on as a major sponsor, and at season's end, a Corvette won! Stu Hayner was the '88 Corvette Challenge Champion. The Corvette Challenge had a huge impact and attracted a wealth of driving talent, such as Andy Pilgrim, Scott Lagasse, John Greenwood, and Boris Said, to name but a few.

For 1989, the wave of success continued. Chevrolet built 60 Corvette Challenge cars under code R7F, but the car got a ZF six-speed manual transmission. The schedule was expanded to 12 races.
