Subject: Proposal for vintage-oriented autocross class.
> Here's a copy of something I just sent to the SEB. It's a proposal for a
> regional-optional vintage autocross class.
>
> Dear SEB,
>
> Grassroots Motorsports has long been a supporter of the national Solo II
> program, with pages of editorial promotion for all of SCCA's efforts in
each
> issue. As you might be aware, our latest venture is the launching of a
new
> magazine for the U.S. market, Classic Autosport. The new magazine will be
> using British Car magazine as a basis and expanding to include marques from
> countries other than Britain. Classic Autosport's goal is to become the
> nexus for all classic sports car activities in the United States.
>
> We'd like to suggest that there is a large market of sports car enthusiasts
> that are interested in autocross and road-rally type activities, as
evidenced
> by the numerous classic marque clubs that hold autocrosses, yet aren't
really
> ever seen at local SCCA events. A few classes for vintage cars at local
> autocrosses (pre 1973) could do for this crowd what Street Touring has been
> working at with the younger crowd. Of course, promotion and support from
> Classic Autosport would be on hand to help this fledgling class, as we
helped
> get Street Touring off the ground in 1998.
>
> Our proposal is to create a class structure that can be included at a
> region's discretion at a local level. The Vintage classes could be based
up
> on the current Street Prepared rules, with several important distinctions.
> Here's an example of what the classes could look like:
>
> General: Cars would be model year 1973 or prior, unless years are
> specifically listed next to the car's entry in Appendix A (example: MGB up
to
> 1978). Updating and backdating would be allowed from cars on the same
line
> in the appendix, up to 1973.
>
> Engine: Preparation would reference SP rules, with the exception of
> intakes. In this case, only carburetion would be allowed. Cars that are
> fitted with factory fuel injection would be allowed, but with no changes
> except for factory ranges of adjustment. Alternate camshafts would be
> allowed.
>
> Suspension: Referencing street prepared, with the exception of only
allowing
> single adjustable shock absorbers without external reservoirs.
>
> Wheels: Wheel width limits of up to 7" wide or 1.5" wider than stock,
> whichever is smaller. Wheel diameters to remain stock.
>
> Tires: This could be handled two ways, one is allowing DOT-approved tires
> that fit under the wheelwells. The second option is to allow only street
> oriented tires (treadwear >140) with an aspect ratio greater than 60%. The
> second option would allow casual marque club enthusiasts to have a better
> chance of success.
>
> Proposed Vintage classes and some sample cars:
>
> V1: Lotus Elan, Porsche 911, TVR
> V2: Chevrolet Corvette, Chevrolet Camaro, Jaguar XKE.
> V3: Alfa Romeo Spider, Porsche 914.
> V4: MGB, Volvo 122, Datsun 510
>
> As a five year volunteer on the SCCA's Stock Advisory Committee, I
understand
> that the last thing the national Solo program needs is a new class at
> Topeka. However, giving a local region the option of including a group of
> people who historically have been shown to be club joiners and club
> volunteers would make many regional SCCA Solo programs even more
successful.
