SPORT CATEGORY

These are the vehicle classing and preparation rules for the Sport Category of SCCA National Time Trials Competition. The intent of Sport Category is that these are daily-driven cars, or absolutely could be daily-driven. We do not guarantee the competitiveness of every car, as it would be nearly impossible and certainly overly complicated. Once you find your car, make sure if it fits in Sport Category by scrolling down to see what modifications you're allowed to do.

Sport Category Classing

In order to best class vehicles in Sport Category, we have based the "cars to have" for each class on the most attainable and desirable cars that are 3–12 years old participating in Track Events and Regional Autocross; the cars people buy when competition isn't their primary goal. Pro series have something called "Balance of Performance" (BOP) to help make cars equal, and you can call the SCCA Time Trials Sport classing a "Balance of Popularity."

If you do not see your car listed, it has not been classed. If you would like to have your car evaluated for classing, use the CONTACT page to fill out a classing request form.

Makes, types and models will be classified by the Time Trials Board (TTB) when requested, and as soon as sufficient information is available to do so. The TTB may reclassify a car at any time up to and including December of the calendar year following that of the initial classification. Initial classification includes the addition of a new listing on an exclusion list.

Sport Category Authorized Modifications

These are the Authorized Modifications for Sport Category vehicles (i.e., what you can do to your car and have it stay in Sport Category). Sport Category, along with Tuner and Max, are restricted rulesets. If a modification is not specifically authorized in these Rules, it is not allowed. (If it doesn't say you can, you can’t.)

The first section outlines the Sport Category philosophy, safety minimums, vehicle eligibility and general modification rules. Following that, the individual sections outline what you can do with each system. (e.g., body, engine, suspension, etc.)

Each set of allowances is broken down into two parts, the first of which are the "Layman's Terms." These are a basic way to describe the intent and allowance. For the rules nerds in our midst, or those who think their modification might be close to OK but not quite sure, there will be a link to the full text rules which fully explains what is allowed.
