I recently acquired an older car and knowing that it would be running with a local SCCA group I had a question Below is a cut and paste of the introduction to a new'ish group within the SCCA world.
HERITAGE CLASSIC
Rationale: The purpose of Heritage Classic (HC) is to enable enthusiasts of sports cars, coupes, and sedans from the early years of the SCCA to participate at SCCA Solo events with cars of similar technology. This participation can range from those just wanting to drive these cars in a competition setting, to those wanting to drive their classic car aggressively for a trophy position. The core objective is to provide a fun experience at the local level for Heritage Classic car enthusiasts through SCCA Regions offering this opportunity using a common set of rules.
Background: These cars from the 1940’s through the early 1970’s are an important part of the history of not only the SCCA, but of the American automotive scene and are worthy of being a part of the SCCA today so this history is not forgotten. The Heritage Classic category is intended to encourage the use and enjoyment of these cars by their owners and other event attendees.
Eligible Vehicles: Vehicle must be from model year 1974 or older and not produced by a United States based manufacturer. Models newer than 1974, but of the same generation as the 1974 model, are allowed. EXAMPLE: a 1978 MGB would be eligible. Vehicle must pass the mandatory safety inspection (tech) and be in compliance with Section 3, of the current SCCA® National Solo® RulesClasses: There are two classes; Heritage Classic Street (HCS) and Heritage Classic Race (HCR). HCS is for street legal vehicles competing on street tires with common enthusiast modifications. HCR is for race prepared vehicles competing on any tires with modifications similar to those common “back in the day”. Additional safety requirements will apply to HCR.
Heritage Classic Street (HCS)
Wheel and Tire Allowances
-
Any metallic wheels are allowed.
-
Any DOT‐approved tires with a UTQG Treadwear Grade of 200 or higher are permitted.
So, having been on the wrong end of guessing what the SCCA rules could mean, I used their system and asked for a clarification.
What does " Any metallic wheels are allowed" mean? Below, the response.
And we have an answer from Doug Gill at the home office:
I’m not the Solo Events Board, but I’ve intercepted your letter #25481 because the SEB does not maintain the Heritage Classic Rules. This is being done in-house here in the SCCA National office.
When the rules says, “Any metallic wheels are allowed,” it means what it says. Solo Rules section 13.4 is not a part of Heritage Classic. The Heritage Classic Rules basically stand on their own “after” Section 12, Definitions. So there is no need to reference any portion of Section 13, Street Category, for an HCS car.
There are no restrictions on the wheel size for HCS. Any 15x6 wheel (or any other size) would be acceptable.
Hope this helps.

What this means, we are released from having to use the stock rims on our cars. In my case the stock rims for a 1961 MGA are 15x4 steel rims that are a riveted two piece design that have a known history of failing during racing events. Yes I know, is auto crossing racing? Now I do not have to squeeze current tires on almost 60 year old rims to find out.
