Historic
PerformanceRally Class Regulations 12.
HISTORIC PERFORMANCERALLY CLASS REGULATIONS
12.1.
PRINCIPLES
The SCCA PerformanceRally Board has created
these Historic Class Regulations to give club members ProRally and
ClubRally license holders an avenue to engage in the active celebration of older
vehicles in PerformanceRally competition.
The intent of these regulations is to preserve the period competition specifications and prevent the
modifications of performance and behavior that could arise through the
application of modern technology. The
spirit of these rules is to enable the fair, cost-efficient and safe
competition of vehicles that are visually and mechanically consistent with
period specifications. for competition use. 12.2.
ELIGIBLE
VEHICLES
12.2.A.
SCCA Eligibility. The Historic PerformanceRally Class is for
four-wheeled two-wheel-drive vehicles manufactured before January 1, 1972.[1] Eligible vehicles
must be a production model built by a recognized manufacturer, but need not have been
homologated. Entries must produce proof of age and a shop manual for the vehicle upon request of an event official during each
annual Historic Class Inspection. A standard SCCA
vehicle logbook per SCCA
ProRally/ClubRally
Rules Section 11 6.1 of the SCCA PerformanceRally
Rules is required.
12.2.B.
Any rally-prepared FIA Appendix K
Eligibility. Notwithstanding
non-compliance with any provisions of Section 12.4 below, any entered vehicle car that conforms to FIA
Appendix K up through period classification G is eligible for the
SCCA ClubRally Historic Class.[2] A competitor
claiming eligibility based on Appendix K must produce valid FIA Historic
Identity Papers for the car vehicle (as required by Appendix K) upon request of an event official during each
annual Historic Class Inspection and are is required to have a standard SCCA vehicle logbook per Section 6.1 of the
SCCA PerformanceRally Rules.
12.2.D.
Canadian and Mexican Eligibility. The Historic Rally Committee created
pursuant to Section 12.5 below (the “HRC”) may permit, on a case by case basis,
entry to vehicles campaigned by Canadian and Mexican citizens and residents who
(1) hold valid C.A.R.S. or F.M.A.D. licenses, respectively, and otherwise
comply with Section 2.1.A.2.(b), and (2) produce a valid vehicle logbook for
the entered vehicle during a Historic Class Inspection conducted prior to the
date of the entered event. Canadian or
Mexican competitors who wish to compete in SCCA events in the Historic Class
must petition the HRC in writing for entry as an Historic Class vehicle at
least 60 days prior to the date of the first event of a calendar year and must
otherwise comply with all provisions of this Article 12.
12.3.
INSPECTIONS
12.3.A.1.
Annual Historic Class Inspections. Eligible Historic Class vehicles must comply with SCCA ProRally/ClubRally Rules
Section 10shall
be inspected annually per Section 6.2 of the SCCA PerformanceRally Rules and such annual inspection shall also
include verification of compliance with, or exemption by waiver from, each of
the requirements of this Article 12.
Each Historic Class Inspection shall be conducted by a scrutineer
designated by the HRC per Section 12.3.A.2 below. The burden to show conformity with the
requirements of this Article 12 shall be borne solely by the
owner/competitor at each annual Historic Class Inspection. All deviations from the requirements of this
Article 12 shall be noted in the vehicle log book and, absent the
existence of a waiver specifically addressing such non-compliance, the vehicle
will not be allowed to compete in the Historic Class. Appeals of adverse determinations by a scrutineer as to
conformity with the requirements of this Article 12 during a Historic
Class Inspection shall be appealable to the HRC in writing.
12.3.A.2.
The HRC shall designate all scrutineers to conduct
the Historic Class Inspections.
Prospective scrutineers shall be considered for such appointment based
upon their experience or expertise in the operation, repair, maintenance and/or
competition configuration of selected makes or models for which the proposed
scrutineer seeks authorization to conduct annual Historic Class
Inspections. Any owner/competitor may
request the HRC to designate a specific scrutineer to conduct Historic Class
Inspections for one or more specified marques by written request to the HRC at
least 45 days prior to an event in which the owner/competitor plans to enter
such marque in the Historic Class.
12.3.A.3.
In order to establish compliance with the
provisions of this Article 12 for use in Historic Class Inspections or for
any other purpose, an owner/competitor may utilize various source materials
which shall, individually or collectively, be considered authoritative,
definitive and conclusive absent reliable information to the contrary. Such source materials may include, without
limitation, factory manuals, period photographs, sales literature, written
contemporary accounts, and publicly available historical literature as well as
written affidavits of past owners, competitors and service crews who provide
first-hand accounts of similar cars’ competition preparation prior to the end
of the fifth year following the end of the model year of the inspected vehicle.
12.3.A.4.
So long as an eligible Historic Class vehicle shall
have passed its annual Historic Class Inspection, such vehicle’s compliance
with this Article 12 may not be protested or contested by an event
scrutineer during pre-event safety inspections per Section 6.3 of the SCCA
PerformanceRally Rules. Such inspections shall be strictly limited
to the same criteria used on all other entries at such event.
12.3.A.5.
All protests as to compliance with this
Article 12 from other competitors shall be in writing delivered to the
owner/competitor and the Series Scrutineer.
12.3.A.6.
The Series Scrutineer shall be solely responsible
for considering all protests concerning compliance with this Article 12
filed at, or within 10 days prior to, an event and shall be the sole arbiter of
such protest. Any inspections carried
out by the Series Scrutineer pursuant to such protest shall be limited to the
specific issues raised by the written protest.
Subject to the right of appeal set forth in Section 12.3.A.7 below,
all determinations by the Series Scrutineer under this Section 12.3.A.6
shall be final and conclusive as to the parties involved. If a vehicle is determined by the Series
Scrutineer to have been altered after the last Historic Class Inspection in
such a way as to render the vehicle no longer compliant with this
Article 12, the Series Scrutineer may prevent the vehicle from entering
further events until the vehicle is returned to compliance or the HRC has
granted a waiver of such non-compliance.
12.3.A.7.
Appeals of adverse determinations by the Series
Scrutineer shall be in writing to the HRC who may uphold or reverse such
determination and such decision by the HRC shall be unappealable.

regulations limit the number of mounting points and the configuration of side
intrusion bars of rollcages in historic vehicles. [4] FIA regulations require that
