2015 SCCA CAM Rules

APPENDIX B - CLASSIC AMERICAN MUSCLE (CAM)

Rationale: The purpose of CAM is to attract automobile enthusiasts who are currently interested and/or participating in Goodguys®, Ultimate Street Car Association®, or other similar events for “classic” vehicles manufactured in North America by “The Big Three” based in the US (GM, Ford, and Chrysler). These avid enthusiasts would largely be a new and different group to join us as SCCA® members and participants. Regions are encouraged to offer this program using a single CAM class or the National Solo® supplemental classes to encourage Classic American Muscle car enthusiasts to join the fun at your SCCA Solo® events!

Eligible Vehicles

•Vehicle must be either a domestic automobile of front-engine/RWD configuration or a “pick-up” truck.

•Vehicle must be licensed and insured and considered fully “street legal” (lights, wipers, etc.). Windshield and glass must be OE or equivalent except as subsequently allowed. Interior and exterior must have a “finished” look.

•Vehicle must pass the mandatory safety inspection (tech) and be in compliance with Section 3, Vehicles, of the 2015 SCCA® National Solo® Rules.

•Excluded: Chevrolet Corvette (1984-2015), Dodge/SRT Viper (all)

CAM-S (Sports) (minimum wheelbase - 90”)

•Seating originally for 2 or more adults

•Wheelbase, minimum (inches) .................................................. ...................................90

•Weight, minimum (lbs.) .................................................. ............................................2600

•Weight, minimum (lbs.) w/ Lexan® windshield .............................................2750

Note: In 2016, OE or equivalent windshields will be required in keeping with CAM philosophy of “no race cars.”

•Side windows may be replaced with Lexan® or equivalent and operating mechanism may be removed or changed.

•Interior floor covering may be removed

Gawd if I had some money, I'd build a wicked 68-70 AMX for the CAM-S class.

If I had the $, I'd build this as a CAM-T monster:

Will Tube frames be allowed?

Tube frames are allowed

There goes the philosophy of simple rules.

I am glad to see the exclusion of the C4 and later Corvettes and the Viper since that class wasn't for those cars (and would probably be dominated by them).

As long as you have a full interior in the car still.

Tube frames aren't mentioned in the rules (as provided). How did you reach that conclusion?

In this case the SCCA understanding that if it's not spelled out in the rules it's illegal doesn't apply because it's already been acknowledged that tube frame cars already exist in Goodguy's and USCA competition.

Not quite true. The interior must have a finished appearance. In all the classes, the back seat my be ditched, headliners are not required, and upholstery and dashes may be replaced. In T and C some form of floor covering is required but what that is open. What they don't want are bare painted floors in those classes.

The class was designed to attract existing cars in the immensely popular Goodguys/USC type series, so that's the ain reason there isn't a ton of rules. A ground-up build to this ruleset would essentially end up being something like a 2wd version of the Ken Block Mustang, if not even more radical.

The ultimate limiting factors will be weight and tires, though. Whatever you build, you still have to weigh a healthy amount, and you still have to interface the ground through relatively narrow 200tw tires. Those factors can offset a lot of technology.

I'm fairly sure the fast drivers will use at least 10" wide wheels all around, so that may not be a big factor for them. I think the Traditional division of the class will be determined by if the car is a tube frame chassis or a muscle car. It's only going to enter in its second year of existence and it seems like it's turning into a "regular" class.

no corvairs :-(

yes that was with a LOL

I don't think anyone would protest a Corvair. (Crown V8? even better!!)

Still scratch my at over the fact that something 2000 or newer can be run in a class called "classic".

That car is actually CP legal.

Too my mind/rationale its silly that they excluded the newish corvettes. At least 50% of the cars built to run these sort of events use c4/c5 suspension with improvements/modifications made for more performance oriented handling over the stock from the factory c4/c5's.

I've got a mind to find one of these c5z06 rollerskates:

and drop a fiberglass/carbon fiber version of this body over the top of it:

I get the intent of their rules but to me its silly to say "you can run a c5 if you want. it just has to be disguised as an old muscle car."

Now I really want an S-Dime with an LSx swap, truckarm rear suspension and some C4 ZR1 wheels/tires/brakes. Someone build this, then get tired of it and sell it for $3k to me.

I'm glad they pushed out the C5/C6. I'd be ok with the early C4 (L98 cars).

If you want to take the time to build the Camaro above, I'd be happy to see it in CAM.

At first I questioned the tube frame allowance, then realized it's to allow Cobra replicas and so on. Sounds reasonable to me.

This should be a fun class and should remain that way unless some idiot decides to make it a "jacket class" in which case it'll go stupid quickly.

While the TW200 rule will keep things somewhat restrained, there is no width restriction and there are some damn wide TW200 tires out there.

It's interesting that one would have to add a few hundred pounds of balast to a bone stock first generation Mustang to be legal.

Honestly, would you be running a bone stock Mustang in CAM against cars that are modified as much as most Pro-touring cars are? Maybe locally it would be okay, most regions don't weigh cars as they don't have the equipment. Weight would come into play at national level events, which should attract the hard core cars more.

I think the 3000 lb weight was chosen as that is a weight most muscle cars can reach.

Admittedly, I am not very familiar with SCCA classes. That said, I understood that the intention of the CAM class was to provide a way for all of the guys with old muscle to run against eachother. If a stock example of one of the most popular (at least by production numbers) old cars is against the rules it seems like the mark may have been missed.

That said, I am happy the the class exists. I know a few people who have avoided auto-x in the past because they were intimidated about being thrown into a modified class on account of their custom fueling (edelbrock carb).

Tubeframe cars should automatically go in CAM-S, even if they have a "sedan" body.

I doubt anyone would protest a weight issue on a stock car. It is funny though.
