GT-1 COMPETITORS TO BENEFIT FROM RULE CHANGE

LANSING, Mich. ‹ The Trans-Am Series for the BFGoodrich® Tires Cup has
modified its engine rules to allow for more participation from GT-1
competitors. The rule legalizes the use of 358-cubic-inch, 13:1 compression
ratio engines in GT-1 cars. The original rule required 358-c.i.-engined GT-1
cars to have a 9.5:1 compression ratio.

The new rule is based on the following restrictions:

* Use of a Holley 390, 4-barrel carburetor p/n 080507-1, with a maximum
throttle bore diameter of 1.4375 inches, and with a maximum venturi diameter
of 1.0645 inches

* A maximum of 8,000 rpm electronic rev limit

* A minimum car weight of 2,800 pounds without fuel and driver

* Driver/entrant must not have competed in a Trans-Am Series race in
calendar years 2002 or 2003

* Drivers must have not finished in the top five in a professional series in
the last five years

* Drivers must have a current SCCA Club or Club/Pro dual license

* Car must conform to all Trans-Am Series specifications concerning safety
regulations, maximum fuel cell capacity, fuel cell installation and
construction, tires, wheels and must maintain a maximum overall car width of
80 inches 

* Car must conform to all other GT-1 competition parameters as specified in
the 2003 Technical Specifications

* Independent rear suspension is not approved

* Car and driver combination is subject to approval by the Trans-Am Series
Technical Director and Chief Steward

³One of our stated primary goals at the beginning of this season was to
encourage GT-1 participation,² said Series Technical Director David King.
³This rule change brings our specifications much closer to the SCCA¹s GT-1
rules and will make it easier for GT-1 teams to compete in the Trans-Am
Series.²

GT-1 entries adhering to the Trans-Am Series¹ engine rules as published in
the 2003 Technical Specifications (310 c.i. and 358 c.i. low compression)
remain eligible for full season competition privileges as specified in
Trans-Am Rule Book Technical Specifications.
