Why it matters
The R9G was a short-lived factory package of 1990 for customers who wanted to go racing. It was available for only one week and only to race teams, so very few cars carry it. The cars left the factory with adjustable FX3 suspension but otherwise as base 5.7-liter Corvettes.
How rare is it?

Every figure says what it counts.

|---|---|---|---|
| Total model production1990 R9G Corvettes (stated as 'twenty three') | 231,2 | Factory production | Registry reported |

History
Chevrolet made the R9G package available for one week in 1990 and only to race teams. Twenty-three cars were built with it. They carried FX3 adjustable suspension and the base 5.7-liter engine, and the buyers were left to do their own race preparation.
