#27793 from Club Racing Board · Recommended to the Board · Minutes (2019-12 Fastrack)
In GCR, section 9.1.1., create new Formula X Rule Set as follows:
“Formula X (FX)
A. Purpose and Philosophy - The Formula X class is intended for winged, open-wheel formula cars of
modest power and performance (sub FB/F1000/FA). The class is to include cars which a) are built in
significant numbers, but not sufficient enough to populate their own class; and b) may not be constructed
to existing class formulas within the GCR. The class may also include cars which have been built to a
recognized SCCA formula but are not running insufficient numbers to warrant their own class. The class is
not intended for unique one-off or prototype open wheel cars which are not widely available; those should

be classed in FS. Power, size and weight of cars which are proposed for classification will be considered
together with their respective performance. It is recognized at the inception that parity among the various
cars that are eligible, or which may be classed, may not exist or be achieved by reasonable means. No car
shall be considered for classification until all specifications of the chassis/tub, aero devices and wings,
suspension, brakes, body, engine, ECU and all associated components have been submitted to SCCA. The
party seeking classification shall be responsible for supplying, at their expense, all necessary technical
specifications for the car along with evidence of performance as may be required by the appropriate
committees and boards. The petitioning party shall further provide, at their expense, all necessary
software, cabling and other peripheral devices required for inspection of electronics and measurement of
unique engine and vehicle attributes. Cars classified in Formula X may, at the discretion of SCCA, be
subjected to periodic adjustments in performance by and through various means including, but not limited
to weight and intake restriction. Cars may be de-classified at any time by SCCA.
B. Eligibility - the following cars are approved for competition within Formula X:
1. Formula Mazda – Shall comply with GCR 9.1.1.E (2019)
2. Formula 4 – Shall comply with FIA Formula 4 Technical Regulations (2015)
3. USF2000 (tube frame) – Shall comply with FRP F2000 Technical Specifications (2018)
C. Engines – Engines which have been sealed from the manufacturer or builder are subject to full
inspection by SCCA stewards and/or technical staff. The competitor shall be responsible for all costs
associated with reassembly and re-sealing of the engine.
D. Electronics – Each competitor shall have available the necessary cabling to permit inspection of
ECU’s and required data acquisition devices. Competitors shall make all collected data available to SCCA
upon request at the end of a session or at other reasonable times
E. Fuel – Shall be compliant with 9.3.25 and other applicable supplemental rules as may be published
by SCCA from time to time.
F. Non-Metallic Chassis Construction – Cars which are proposed for classification which feature non-
metallic chassis construction must comply with 9.3.35. Certifications must be on file with the SCCA
Technical Services Department in advance of the car being classified.
G. Restraint Harness – Driver safety harnesses must comply with 9.3.18.
H. Fire Suppression Systems - Fire suppression systems must comply with 9.3.22.
