Spec E30


Spec E30 is a class of racing cars used in National Auto Sport Association road racing events.

Concept

The goal for Spec E30 is to create high levels of competition among similarly prepared BMW E30 3 Series cars at a reasonable cost. It is intended to encourage low-cost, entry-level, production car based competition. It has been called "the next big thing" in club-level racing by Grassroots Motorsports Magazine.

Cars

The series consists of U.S.-spec BMW E30 325i coupes and sedans, sold between 1987 and 1991. All cars in the series use the BMW M20B25 engine. Convertibles built to series specs and with log books issued prior to November 1, 2011 are still allowed to compete, but this model has been sunsetted out of the series.
As a "specified" class, the rules allow for a limited number of modifications, predominantly involving required suspension parts.
