Re: Proposed Re-structure of Stock Classes

The SCAC proposes a restructuring of the stock car classes to better reflect the current sports car marketplace and to thereby better serve the membership.

Current SCCA Solo_II Stock classification listings are good, but do not serve the evolving "sports car" market. Over the years, the SCCA has tried to be as inclusive as possible in offering a class for just about any four-wheel street-driven passenger vehicle. What has evolved from this is a system which is better at classing economy cars than it is at classing "sports cars". This has been the case primarily for what are now Classes D-Stock, E-Stock, and H-Stock. These are relatively low horsepower cars which are largely 2+2 or four passenger vehicle configurations. Pure two seaters are in evidence here and there, but they are never found as "class leaders". While D-Stock has come to be dominated by economy sport sedans, over the years E-Stock and H-Stock have had many vehicles overlap in terms of performance. Both of these classes are comprised of economy four-cylinder sedans or GT style coupes, a few low-power 6-cylinder cars, and a few older two seater sports cars.

We also have classes for the 2+2 high horsepower pony car: Mustang and Camaro types in F-Stock, and the recently revised "older small displacement sports cars" which define C-Stock. Like D, E, and H, these classes are also comprised of vehicles which are not at the upper end of the sports car market in cost of acquisition. Yet F-Stock and C-Stock each serve a distinct market segment.

Moving upscale in dollars, what that leaves us is a mid-priced vehicle segment in B-Stock and G-Stock. Each of these classes has a very distinct outreach. B-Stock is home to the Miata, the BMW Z-3, Porsche 914, and a few others. Most are true two seater sports cars with normally aspirated engines, light weight, and not considered "expensive" to acquire or operate. G-Stock is home to a variety of sports coupes, some with turbo charged motors, and most with roughly 200 horsepower or so. Some are all-wheel drive, some front- wheel drive, and some rear-wheel drive. It's a very diverse sports and sport sedan class. Because the technology and drive systems in this class are somewhat more advanced than in B-Stock, vehicles in this class may carry an appropriately higher price tag.

And that has left us with just two classes at the top of the Club for the "up market" sports cars and sedans- Super Stock and A-Stock. Until about ten years ago, this was working just fine. Since the early 1990s, however, the vehicle manufacturers have brought a wide variety of high performance vehicles to market. The effect on the top two classes has been noticeable, with the C4 Corvettes losing ground to the RX-7tt at first, and the balance of Super Stock left in the weeds. As manufacturers kept increasing the horsepower and performance of their high end sports cars, vehicles that threatened to dominate the Super Stock status quo were put into Street Prepared classes where they were rendered uncompetitive. We don't see that this is satisfactory for the membership, and especially not for an organization called the Sports Car Club of America. What we propose is to redistribute the existing Super Stock sports cars into two classes, thereby making an accomodation for the new breed of vehicles being produced . Rather than adding to the existing number of stock classes, however, we feel it's time to redistribute the "load". Presently, the type of vehicles running in E-Stock and H-Stock are nearly identical. The performance is so close that it is the Stock Classification Advisory Committee suggestion that these two classes can be combined.

What we further propose is to enhance the existing framework by setting up each class with representative vehicles, and class-similar types with those vehicles. What follows is the list of class representative vehicles in nine Stock category classes. Again, this is not an increase in classes but a redistribution of vehicles to better reflect the market dynamics we've been experiencing for the past ten years, and expect will continue into the next decade.
