competitors with Toyota-powered cars believe their cars have such a deficit and are interested in seeking a BoP adjustment, it is

spec – 2025 USF Pro 2000 rulebook specifications, which differ from the specifications of the 2024 cars that were used for
comparison. A review of the available information indicates that the 2025 specifications provide for a rev limiter RPM increase
that results in higher peak horsepower as well as a substantial gain in bottom end horsepower compared to the 2024 version of
the USF Pro 2000 car.

#36171 from John Harkenrider · Not recommended · Minutes (2024-07 Fastrack)
Thank you for your letter. The Club Racing Board does not recommend this change. Grand Touring and Touring are
not split classes. GT1, GT2, GT3, and GTL are independent classes in the Grand Touring category and T1, T2, T3, and T4
are independent classes in the Touring category. These classes may or may not race together in a run group based on
the event, and at the Runoffs the classes typically have separate races. FA's average participation level in U.S. Majors
Tour events does not support dividing the class into separate classes for different car types. In situations where a
disparity in performance exists within a class for a particular car, car owners have sometimes organized an unofficial
championship for that car type within their class and/or recognized individual competitors' performance by awarding
their own trophies and taking their own podium pictures. This has worked well both regionally and nationally but
does require organization on the racers’ part.

#36032 from John Harkenrider III · Not recommended · Minutes (2024-05 Fastrack)
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 Pro Formula Mazda is classified as a "Spec Line Car" under FA Table 2 because its engine,

#34979 from David O'Leary · Not recommended · Minutes (2023-12 Fastrack)
Thank you for your letter. Runoffs attendance in recent years has been carefully reviewed, as has the competitiveness of F1000
cars with the other FA cars, and the results do not support a claim that F1000 cars cannot be competitive in FA, particularly
when using modified older or current (newer) 1000cc engines rather than the original stock engines. An F1000 car qualified third
quickest out of 18 entries in the 2021 Runoffs at the Indianapolis Motor Speedway. In the 2022 Runoffs at Virginia International
Raceway, F1000 cars qualified second and third quickest and finished first and second in the race. The low FA entry numbers at
the 2023 Runoffs do not reflect the class's normal participation level. During the 2023 season, FA averaged 3.5 cars per U.S.
Majors Tour event, which placed the class 14th out of the 25 Runoffs-eligible classes. Given the competitive performance and
entry numbers of F1000 cars during the 2022 Runoffs, no basis is seen for claiming that the low FA entry at the 2023 Runoffs was
the result of negative performance expectations for F1000 cars. Low entries are often less of an indication of performance
expectations within a class and more of an indication of how classes are attracted to particular venues. For example, the 2023
Hoosier Super Tour event at Virginia International Raceway had just three FA entries, while the 2023 Hoosier Super Tour events
at the Circuit of the Americas and Road America had 19 and 20 FA entries, respectively. The 2023 Runoffs FA entries duplicated
this trend. Apart from the apparent competitiveness of F1000 cars in FA seen in recent years, which weighs against a need to
restrict other FA cars or to reclassify F1000 cars, F1000 cars do not satisfy the formula in FC, and the FC rules expressly state that
"spec line cars" and performance balancing are disfavored in that class. F1000 cars were not reclassified to "save" the FA class:
The F1000 (FB) class was discontinued as a U.S. Majors Tour class because of chronically low participation. In 2016 and 2017,
participation dropped to 2.8 cars per Majors event. In 2018 the average participation continued to decline to 1.1 cars per Majors
event, and in 2019 the class averaged just 0.67 cars per Majors event. In light of this well-documented downward trend, there
was no expectation that F1000 would "save" the FA class; the cars were reclassified in FA to give them a place to run where they
could be competitive. In fact, the participation level near the end of the separate F1000 class continues to this day, despite the
proven competitiveness of the cars in FA in recent years. In 2023, F1000 cars accounted for 0.67 cars per Majors event —
identical to their participation in the final year of the F1000 class, which leaves no basis for expecting that participation of F1000
cars would increase if they were moved to a different class.

Thank you for your letter. Formula Atlantic was originally created as a true formula class, with cars built to a formula or set of
rules, which left open a pathway for constant development and technological improvements. In recent decades, however, as
various pro and semi pro series have developed, core formula classes such as Formula Atlantic have been steadily displaced in
favor of proprietary spec cars. After the pro Formula Atlantic series abandoned the concept of Formula Atlantic as a true formula
class, the SCCA continued to allow purpose-built and ex-pro Formula Atlantic cars to compete in the Formula Atlantic class in the
Road Racing program, but also permitted proprietary spec cars and other classes of cars with similar performance capabilities to
compete in the class. This will be the case for the foreseeable future. The Formula Atlantic preparation rules provide the basic
specifications for cars eligible to compete in the class. Table 1 lists the approved 1615cc engines and associated specifications for
purpose-built and ex-pro Formula Atlantic cars, while Table 2 (Spec Line Cars) lists other approved chassis and engine
combinations with any exceptions to the basic specifications for the class. The specifications for cars permitted to compete in
Formula Atlantic through the Table 2 spec lines are tightly controlled to avoid having these cars break out of their previously
described performance envelope. The Club Racing Board intends to maintain the class at the current performance level. The
SCCA will welcome other spec open wheel cars from other racing organizations and will attempt to classify them based on their
relative performance and mass. These cars, assuming that they fall within the appropriate envelope of performance and mass,
may be classified in Formula Atlantic once their performance, specifications, and rule sets are established, but the SCCA does not
plan to allow hybrid versions of these cars, i.e., combinations of components from different spec classes.

acceleration rate of the Swift 014a – Mazda MZR 2.0, so adjustments to the 016a's intake restrictor and minimum weight are not
warranted at this time.
#29642 from DAVID OLEARY · Not recommended · Minutes (2020-12 Fastrack)
Thank you for your letter. The Club Racing Board does not recommend these changes. The F1000 pole position time at the 2013
Runoffs (2:04.786) compares favorably with the FA pole position time at the 2020 Runoffs (2:04.274), and the current rules also
permit modification of F1000 engines in FA. Please see the responses to letter #27319 in the January 2020 Fastrack Technical
Bulletin and letter #28162 in the April 2020 Fastrack Technical Bulletin.
#28573 from William Wald · No action required · Minutes (2020-04 Fastrack)
Thank you for your letter. Please see the response to letter #28507 in this Fastrack. The Tatuus PM-18 is
a different car than the proposed Formula Mazda FMzR, and the Club Racing Board's
recommendation regarding the FMzR in letter #27712 in the January 2020 Fastrack Minutes does not
apply to the PM-18.
#28507 from William Wald · Not recommended · Minutes (2020-04 Fastrack)
Thank you for your letter. The Club Racing Board does not recommend this change because the car is
not within the intended performance envelope of the FA class.
#28179 from Dudley Fleck · Not recommended · Minutes (2020-03 Fastrack)
Thank you for your letter. This change is not recommended at this time. The Club Racing Board will

#28675 from JEREMY HILL · Taken care of · Minutes (2019-05 Fastrack)
Thank you for your letter. F1000 cars are no longer required to use stock engines, and a 25-lb. allowance
for cars with engines manufactured before 2011 is not warranted because competitors are now
permitted to make any modifications and use any engine components they wish to run, subject to the
requirements of the F1000 spec line and the general FA rules. Please see the response to letter #28162
in the April 2020 Fastrack Technical Bulletin.
#23725 from Moses Smith · Not recommended · Minutes (2019-05 Fastrack)
Thank you for your letter. The CRB does NOT RECOMMEND and is unable to classify the Pro
Mazda Tatuus PM-18 in FA due to the absence of engine build, mapping and performance
specifications. While the CRB will consider and approve sealed engines for use in SCCA Road
Racing, all pertinent build and performance related criteria must be provided for purposes
of approving the classification and ultimately for publication in the GCR so as to permit
compliance inspections as may become necessary in the course of competition.

Thank you for your letter. Please see the responses to letter #26322 and letter #26063,
February 2019 Fastrack Technical Bulletin.
#26322 from Bill Gillespie · Not recommended · Minutes (2019-03 Fastrack)
Thank you for your letter. The Club Racing Board does not recommend this change. The Swift
016 has hard points on both sides of the cockpit for installing ballast, and adding weight is
a more cost-effective solution than the dyno work and re-tuning associated with a restrictor
change.
