Vehicle Classifications

 

ISCA COMPETITION CLASSIFICATIONS

This classification listing has been approved by the International Show Car Association and is recommended for use at each sanctioned event. Only the “base” classes (in bold print) are used in determining Class Championships. The classes may be further broken down, as indicated, at the discretion of the
judging supervisor for each show.

Occasionally, vehicles may appear to qualify for more than one classification. It is the intent of the ISCA to place such vehicles in the most suitable classes based on construction and appearance. Responsibility for initial classification of this type
vehicle will rest with the individual supervisor in attendance at the first event in which it competes.

CUSTOM CATEGORY

Changes are minor alterations to a vehicle such as removing chrome, bolt-on bumpers and grilles, simple nosing or decking (which do not involve body work). Four or more changes constitute a modification. The number of modifications are
counted in determining the classification of vehicles in the Custom Category.

Ten or more brightwork items (including polished or brushfinished chrome, gold, aluminum, or brass plating) on undercarriage and on engine and engine compartment will count as one modification each area; does not include fasteners.

Modifications include, but are not limited to, the following (one modification each): only special paints (the use of candy, pearl, flake, scallops, flames or any type of trick paint); shaved door handles, scoops, headlight alterations (involving body work); tail light alterations (involving body work); grille alterations (involving
body work); rolled pans and wheel-well alterations (involving body work); engine conversions and interior alterations (no matter how extensive); independent rear-ends; conversions; ground or cherried block; lights or other items molded into a
bolt-on spoiler; molded and/or filled frames, filled firewall and flat or padded vinyl tops that involve body work. Filled inside door edge seams and louvers do not count as modifications.

Any major work to a chassis that requires cutting and welding, such as front suspension changes (I-Beam to independent, etc.); rear suspension changes, such a rear end housing changes (Ford to Chevy, coil over shocks instead of springs, Air ride type suspension); “C’ed” frames, etc., counts as one modification per occurrence front and rear. (The one modification per occurrence front and rear counts with regard to the above listed work, but is not limited to just that work.)

Supervisors and judges must always keep in mind the amount of work that was required to accomplish the complete vehicle, even if some of the work is hidden.

Where classes are split into Conservative, Mild, Semi, Full and Radical, splits will be based on vehicle having the proper number of modifications for the classification:

CONSERVATIVE
0-3 modifications

MILD
4-6 modifications

SEMI
7-10 modifications

FULL
10 modifications

RADICAL
Any number of modifications, at least one of which is
chopping, channeling or sectioning.

RESTORED CATEGORY

All restored, original and antique vehicles will be classified according to ISCA rules and regulations. These are not necessarily in line with classifications set by antique or restored governing bodies.

Stock vehicles from 2012 through current year no longer compete in the Restored Category. These vehicles are now classified in their appropriate category — Custom, Sports or Truck.

In the Restored Category, when an exhibitor puts his/her car on the show floor, the judging supervisor will decide if the intended appearance of this vehicle is as a restored vehicle. Once it is determined that the intent is to show a restored vehicle, and that none of the following non qualifiers have been done to the vehicle, then we will judge those types of vehicles just as we do the other categories, on quality and quantity of work.

Because of the wide range of vehicles that could be shown in this category, we cannot be critical about percentages of gloss on painted areas, such as — but not limited to — core supports, inner fenders, suspension parts, etc. Keep in mind that these areas may not be metal finished, mudded up to smooth them out, welds removed, cherried, etc.

Also, another area that will not be a reason to move a vehicle out of this category would be either unpolished stainless steel or coated, stock-appearing exhaust systems, example; jet hot coatings.

Amounts of over spray on engine components or undercarriage areas will not be a factor in classifying vehicles in this category. Another area that will not affect classification would be painted or coated gas tanks for rust protection only. Galvanized or non gloss paint would be acceptable. Gloss paint, black or car color, is not acceptable; no body work or puttying may be evident in this area.

ISCA’s purpose in offering this category to our exhibitors is, as always to give everyone a place to show their vehicles. It is not fair to be critical of a given kind of car because the judge happens to know those cars and then let other cars slide by because of lack of detailed knowledge pertaining to these other vehicles. The judging staffs cannot know all things about all cars.

As always, the judging supervisor and competition committee will have final say so in all classification questions.

In Restored Category, for purposes of differentiating between pure antique or fully restored vehicles and those with slight alterations (changes), the following criteria has been established. Vehicles which are original or restored as close to original as possible (0 to 1 change) will be split by year-break (classes 7010.0 thru 7095.0). Vehicles which have two changes (such as upholstery material, vinyl top, steering wheel, gauges) will move to “altered”. Vehicles with more than two minor changes will move into Custom Category, Truck Category or Rod Category, depending on body style.

Any of the following (but not limited to) changes will move an entry out of the Restored Category and into its respective category and class:

1. Special paint (i.e. major color change, custom pinstriping unless original appearing).
2. Metal working of frame for removal of holes, stress marks, spot welds, etc.
3. Cherried door jams, no matter how extensive. Final determination will be made by Competition Committee
4. Any aftermarket wheels
