In GCR, Section 9.1.9.1. TOURING (T1) CATEGORY, add the following:
“Touring 1 Rules for GT4 and Homologated Cars.
Touring 1 is comprised; 1) Race modified USDM cars (discussed above), 2) GT4 cars originally built for pro racing, and 3)
Homologated cars which were built to conform to a different series or spec sheet. These are the category rules for Touring 1 GT4,
homologated, and purpose built cars. Cars in this category include, but are not limited to SRO GT4, and Spec Corvette. To be
eligible to compete in Touring 1, the car must conform to these category rules and the following spec lines. Each spec line below
includes a column named “must conform to”. At all events ,it is the driver’s responsibility to provide the applicable
homologation documents. Factory built race cars must conform to published specifications.

Q. Eligible cars-
1. GT4 and Homologated cars must be based off of USDM models. Only cars listed in the spec lines below are permitted
to compete in Touring 1. Lightweight and Non-USDM models (ie. KTM X-Bow or Ginetta G56) will not be classed.
2. New classifications will be considered pending a complete request through the SCCA’s letter system. Newly created
spec lines will be required to complete at lease 3 Super Tour weekends before the spec line is eligible for Runoffs
competition. This ensures reasonable data collection and comparison prior to qualifying to enter the national
championship race.
R. Approved modifications to homologated cars- All cars must conform to the rules set defined in their spec line unless
otherwise noted below.
1. Cars built with front windows are permitted, but not required, to remove them.
2. Safety equipment: Seats, Belts, Nets, and steering wheels may be replaced with SCCA compliant alternatives. All cars
must meet SCCA cage and safety standards.
S. Fuel- Cars must use fuel that conforms to section 9.3.25 or to the Runoffs Supplemental regulations.
T. Tires- Tires must conform to GCR section 9.3.45 Tires and also must conform to spec line requirements. DOT approved tires
are required.
U. Performance adjustments- The spec lines include specific requirements to achieve parity with other Touring 1 cars. These
may include specific ECU programming, inlet restrictors, weight, etc. Notes in the spec lines supersede rules set forth in these
category rules. Each spec line defines which rules set it must conform to.
V. Labeling-
1. These rules may include many options that affect a vehicle’s competition weight.
a) The competition weight must be shown on both sides of the car. The competition weight is the sum of
the spec line weight and all weight modifiers, penalties and allowances.
b) In order to inform competitors, spectators and tech officials, competitors are required to declare their
spec line number. Touring 1 spec lines have a column called “spec line number”. This number is to be presented
legibly, behind the driver’s window in a font greater than .75 inches tall. The formats “Spec Line #XXXX” and
“SL# XXXX” are recommended.”
