Thank you for your letter. The Club Racing Board does not recommend this change. SCCA cannot guarantee that cars from a discontinued pro series will have their own U.S. Majors class or will be fully competitive in a Majors class in which other cars have been built to a specific "formula." In FA, the Pro Formula Mazda (PFM) spec line in Table 2 no longer requires PFMs to comply with the rule set from their former pro series. The PFM's sealed-engine requirement was removed effective January 1, 2018, and owners are now permitted to port their engines and run wider wheels. PFMs also benefit from certain accommodations that are unavailable to other cars in FA, including allowances for a higher-mounted rear wing, wider bodywork behind the front wheels, and a 6-speed transmission. PFM owners are free, alternatively, to

bring their cars into compliance with the general FA rules and use one of the approved engines from FA Table 1. While a PFM running under the spec line may not be able to compete head-to-head with some cars in FA, the PFM's performance level far exceeds the performance level of every car classified in the FX class, and it would therefore be inappropriate to reclassify PFMs in FX. In addition, PFMs do not participate at a level nationwide that would justify creating a separate U.S. Majors class. PFMs accounted for just 25 entries in FA during the most recent U.S. Majors season (19.8% of the total FA entries in 2023) and achieved an average entry of only 0.71 cars per event, which is far below the participation level expected of a U.S. Majors class. PFM owners are welcome to consider concepts such as organizing an unofficial championship within FA and/or recognizing competitors' performance by awarding PFM trophies and using custom backdrops for PFM podium pictures.
Thank you for your letter. The Club Racing Board does not recommend either of the suggested classifications at this time. The Tatuus USF-17’s carbon fiber chassis is inappropriate for classification in FC, and the available information indicates that the USF-17's performance may be superior to that of the cars currently classified in FX. The advisory committee attempted to obtain additional information about the USF-17 from the writer but received no reply. The committee will need complete specifications for the USF-17 if the writer remains interested in classification.

Regarding the request for a weight reduction for the Formula Mazda, please see the response to letter #33010 in this Fastrack's Technical Bulletin.
Thank you for your letter. The Club Racing Board appreciates your comments. Please see the response to letter #31496 in this Fastrack regarding seal numbers. The computer program needed to verify the USF2000’s ECU map should be readily available to tech officials because the car uses the same ECU as FC. The Club Racing Board will recommend that tech officials have access to a Go-No-Go restrictor tool for all cars in the class equipped with restrictors and a carburetor tool to check the FM cars.
Thank you for your letter. The Club Racing Board does not recommend this change.

Thank you for your letter. The Club Racing Board appreciates your comments. F1000 competitors were not told to increase their participation numbers or be reclassified into Formula Atlantic. Rather, they were notified in the January 2019 Fastrack that F1000 would be discontinued as a separate class effective 1/1/2020 in connection with the incorporation of F1000 cars into Formula Atlantic – similar to the notice that Formula Mazda was being discontinued as a separate class in connection with the incorporation of FM cars into Formula X. Please see the response to letter #25823 in the January 2019 Fastrack. As with F1000, FM's low participation numbers were posted on the SCCA website and provided a full year's notice of the need to improve the class's participation level in accordance with GCR section 9.1.13.A. Please see the response to letter #28047 in the February 2020 Fastrack.

Formula X is intended to provide a place for cars that do not participate in sufficient numbers to populate their own class, and FM cars are an integral part of the class. During the 2021 U.S. Majors season, FM cars accounted for approximately 60% of the entries in FX. With FM's participation, FX was able to achieve an average of 4.0 cars per event during the 2021 season. The FX rules do not guarantee parity among the various types of cars classified in FX. GCR section 9.1.1.J.A expressly states: "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." Entrants are free to organize an unofficial championship for FM competitors within the FX class or to otherwise recognize FM competitors' performance in FX. Please see the response to letter #28050 in the February 2020 Fastrack.

The spec tube-frame Formula Mazda chassis classified in FX fully complies with all current safety requirements and technical regulations in the General Competition Rules. Limiting open-wheel run groups to a maximum of 20 cars (and thereby increasing the number of run groups) is not feasible because of the time constraints inherent in race weekends. P1 cars have successfully run with open-wheel cars (including FA, FB, FC, FE, FE2, FM, and FX) since the class’s inception; on-track problems of the type described should be addressed with the Stewards. Car classifications are reviewed in response to member input and in conjunction with analyzing on-track AiM data.
