Want to know where your car is classed for SCCA Time Trials National Classing? Follow these steps.
(Note: Not all Regional Events use National Classing. For questions about Regional Event classing, contact the event organizers.)

1) Pick the Category You Believe Fits Your Car the Best

Sport Category is intended for daily-driven street cars on tires with a treadwear rating of 200 or higher with simple bolt-on modifications.

Modifications typically allowed in Sport:

  • OBD-based ECU reflashes
  • Most wheels
  • Single-adjustable fixed-perched shocks
  • Lowering spring kits
  • Direct-replacement sway bars
  • Cold-air intakes
  • Cat-back exhausts
  • Radiator and fluid coolers
  • Brake option packages and some cosmetic modifications from a different trim model of the vehicle—like swapping spoilers

Ultralight wheels, aftermarket camber-adjustment, ride-height adjusting coilovers, racing springs, speedway-style sway bars, chassis bracing and aftermarket-ECU are not allowed. Click here to find the full Sport Category Rules.

Tuner Category is intended for street-driven vehicles on tires with a treadwear rating of 200 or higher with bolt-on modifications that allow for tuning and adjustment. Everything still has to bolt to the stock places, but this is where you will find the ability to include the following:

  • Intercoolers and boost controllers on forced induction cars
  • Headers
  • Caster/camber plates
  • Ride-height adjustable coilovers
  • Racing springs
  • Highly tunable sway bars
  • Aftermarket ECUs for non-OBD cars
  • Aftermarket big brake kits

Click here to find the full Tuner Category Rules.

Prepped Category is intended for streetable vehicles on tires with a treadwear rating of 200 or higher with highly adjustable bolt-on parts, and some engine modifications. You can consider this class "Tuner Plus."

Everything in Tuner—which includes intercoolers and boost controllers—along with coilover suspensions, big brake kits and fancy sway bars, but now the car can have full exhaust and custom ECUs.

In addition, in Prepped Category competitors can "pick one" of three sets of engine modifications. 

Option 1: Engine swap as long as the engine is stock and from the same manufacturer, or;

Option 2: Stock engine, but naturally aspirated engines can have any intake manifold (even custom ones), while camshaft and forced induction engines must keep the stock intake manifold and throttle body, but can change any of the intake and exhaust piping, or;

Option 3: Stock engine with added aftermarket forced induction, but the intake manifold and throttle body must remain stock.

Max Category is for what we consider the "Maximum" street cars. Maybe they only get driven on Sundays, or are pure track cars which could be driven on the street. This is where you find engine swaps, aftermarket or increased forced induction, suspension geometry changes, or even aftermarket wings and bodywork. Click here to find the full Max Category Rules.

Unlimited Category is for those production-based vehicles that are not street-going, are pure race cars, or are on DOT tires with less than 200 Treadwear or non-DOT racing tires. This is where you find tube frame race cars, giant wings, ground effects, stripped interiors and the fastest of the fast.

This is where we're going to put cars that might not quite meet the rules, but we think they can go in this category anyway.

1. Cars listed as eligible in and prepared to the SCCA Road Race National Touring 2, 3 and 4 Rules are permitted to compete in their respective Time Trials Tuner Class provided they run on Time Trials legal tires. Vehicles with this allowance are not permitted to interchange preparation rules otherwise.

2. Cars listed as eligible in and prepared to the SCCA Road Race National Spec Miata Rules are permitted to compete in Time Trials Tuner Class 5 (T5) provided they run on Time Trials legal tires. Vehicles with this allowance are not permitted to interchange preparation rules otherwise.

Note: SCCA Solo Street Prepared has been rejected for Tuner Category inclusion because a full-tilt Street Prepared car is an engine-swapped, intake-manifold customized Frankenstein creation which is awesome, but doesn't belong in Tuner Category.

Prepped 1 (P1) eligible vehicles include:

1. Naturally-aspirated vehicles with an engine displacement of no more than 6.5L, not weighing less than 3,000 lbs. (with driver).

2. Forced-induction vehicles with an engine displacement of no more than 4.334L, not weighing less than 3,000 lbs. (with driver).

3. Naturally-aspirated vehicles with an engine displacement between 2.995 and 3.9L which weigh less than 2,600 lbs. (with driver).

4. Forced-induction vehicles with an engine displacement between 1.997 and 2.6L which weigh less than 2,600 lbs. (with driver).

Prepped 2 (P2) eligible vehicles include:

1. Vehicles with a real or corrected displacement of no more than 3.9L, not weighing less than 2,600 lbs. (with driver).

2. Vehicles with a real or corrected displacement between 1.995 and 2.995L which weigh less than 2,200 lbs. (with driver).

Prepped 3 (P3) eligible vehicles include:

1. Vehicles with a real or corrected displacement of no more than 2.995L, not weighing less than 2,200 lbs. (with driver).

2. Vehicles with a real or corrected displacement of 1.995L or less which weigh less than 1,900 lbs. (with driver).

Prepped 4 (P4) eligible vehicles include:

1. Vehicles with a real or corrected displacement of no more than 1.995L, not weighing less than 1,900 lbs. (with driver).

This is where we're going to class cars that might not quite meet the rules, but we think they can go in this category anyway.

1. Cars listed as eligible in and prepared to the SCCA Road Race Improved Touring National Rules are permitted to compete in their respective Time Trials Prepped Class, provided they run on tires legal for Time Trials. Vehicles with this allowance are not permitted to interchange preparation rules otherwise.

A. Improved Touring cars are not limited to the spec wheel sizes.

B. Regional-only Improved Touring cars—e.g., "ITE"—do not fall under this allowance.

To determine the corrected displacement for classing purposes, the following formulas will be used:

1. Rotary: Actual displacement X 2.0

2. 2-Cycle Engines: Actual displacement X 2.0

3. Forced induction: Actual or corrected displacement X 1.5

A. For each additional forced induction unit 0.5 should be added to the forced induction displacement modifier (e.g., twin charged, twin turbo: Actual corrected displacement X 2. Quad turbo: Actual displacement X 3).

Max 1 Category Eligible Vehicles Include:

1. Any production vehicles with a real or corrected displacement of more than 5.1L. 

2. Any production vehicles with a real or corrected displacement between 2.61 and 5.1L that weigh less than 2,250 lbs. (with driver).

3. Any production vehicles with less than 2.61L displacement that weigh less than 1,500 lbs. (with driver).

MAX 2 (M2) Eligible vehicles include:

1. Production vehicles with a real or corrected engine displacement between 2.4 and 5.1L, not weighing less than 2,250 lbs. (with driver).

2. Production vehicles with less than 2.61L displacement that weigh between 1,500 and 1,750 lbs. (with driver).

MAX 3 (M3) eligible vehicles include:

1. Vehicles with a real or corrected displacement of less than 2.61L, not weighing less than 1,750 lbs. (with driver).

To determine the corrected displacement for classing purposes, the following formulas will be used:

1. Rotary: Actual displacement X 2.0

2. 2-Cycle Engines: Actual displacement X 2.0

3. Forced induction: Actual or corrected displacement X 1.5

A. For each additional forced induction unit 0.5 should be added to the forced induction displacement modifier (e.g., twin charged, twin turbo: Actual corrected displacement X 2. Quad turbo: Actual displacement X 3).

The following kit cars are eligible for Max Category:

1. Shelby Cobra Models

2. Shelby Daytona Coupe Models

3. Corvette 1963 Grand Sport Models

4. Ariel Atom

5. Exocet

6. Noble M400/M12 and Rossion Q1

7. Brunton Auto  - Stalker

Cars which are production silhouette, but are over the displacement limits or under the weight limits for Unlimited 2. (U2)

1. U1 minimum weight: None

Cars which are production silhouette and meet the following criteria:

1. U2 minimum weight:1,750 Lbs. (With Driver.)

2. U2 Maximum Displacement, 3.0 Liters corrected displacement.

Being an enthusiast is wonderful, there are so many choices in modifications, series and formats for #funwithcars. Here is a guide to help you find where your car and particular set of modifications fits within our Rules.

1. Write down everything done to your car. Sit down with that list and your beverage of choice and start at Rules – Sport Category.

2. Start at "Interior" and click the links, comparing your list with what's allowed; make sure to remember, "if it doesn't say you CAN, you CAN'T."

Some of the major things that would move you up to Tuner Category are:

1. Ride-height adjustable shocks.
2. Headers and the removal of catalytic converters.
3. Intercoolers, supercharger pullies, mechanical boost control.
4. Standalone, chipped ECUs or ECUs with piggyback-style programming.

3. If you get all the way to the bottom and everything you did is allowed, find your car in the Sport Category classes in Step 2. If your car isn't classed or excluded, ask us to class that year, make, model and trim level using the Contact page. 

4. If you did find something that your car has which isn't allowed in Sport Category, then go to Rules – Tuner Category and start the process again.

Some of the major things that would move you up to Max Category are:

1. Putting an aftermarket splitter or wing on your car.
2. Doing any internal work to your engine (cams, oversized pistons, etc.).
3. Changing the throttle body or intake manifold.
4. Swapping your engine for one that didn't come in your model and trim level car.

5. If you get to the bottom and everything you did is allowed, find your car in the Tuner Cateogry classes in Step 2. If it isn't classed or excluded, ask us to class it using the Contact page.

6. If you find something on your list that isn't allowed in Tuner, (I bet you see where this is going) go to Rules – Max Category and start at the top.

Some things that would move you up to Unlimited Category:

1. Interior carpet, seats and trim removal without adding safety equipment like a roll bar or roll cage.
2. Having "R-Compound" tires—that is any tire under 200 Treadwear—or non DOT racing tires on your car.
3. Having massive aftermarket aero like huge wings, big diffusers and large splitters.
4. Having a tube frame car, or car with huge changes to suspension geometry and construction.

7. If everything on your list is allowed in Max, then use the classing formula for the Category in Step 2 to determine your class. (We don't class individual cars here, other than the list of approved kit and reproduction cars.)

8. If you find something that isn't allowed in Max, congrats! You have a race car or a creation close enough it may as well be. You're in Unlimited Category. Read the Unlimited rules to make sure you're still good to go. (Mr. Musk we won't tell you again, you may run your Roadster in SCCA Time Trials, but not if it's attached to your SpaceX Falcon.)

Still don't see your car? Use the "Contact" page to ask us for help or to have your car classed!
