The Import Drag Racing Circuit (IDRC) was founded in 1998 to take the sport of import and sport-compact drag racing to a new level. The IDRC was the first to produce a national import drag racing event with the best racers from the West Coast facing the best racers from the East Coast. The IDRC was also the first organization to work directly with the NHRA to coproduce an event. Our hope was to bring a the NHRA’s sponsors to the sport that we loved. For various reasons, professional-level import and sport-compact racing would never grow to a level where it would be able to sustain itself. When General Motors and million-dollar budgets went up against the privateer import racers, it wasn’t long before cubic dollars won the war. By 2002, professional import drag racing was to be abandoned by the fans, the racers and the sponsors. Many organizations pulled the plug, but we shifted gears. We continued to produce events across the country that would focus on the privateer and grassroots racer.

Last year, we launched a new rulebook with new classes designed to lay a foundation for semi-professional import and sport-compact drag racing to make a return. The rules and classes were engineered to provide exceptional parity and competition in the class. Unfortunately, they were probably a little too far ahead of their time. For 2015, we looked for a solution that would deliver classes and rules that were more basic, simple and fun. Hence, the IDRC is doing another first. The first “index” classes for import and sport-compact drag racing.


  • Event FAQs

    I’ve never been to an IDRC event and my friends and I are thinking about going. Can we bring food and drinks?

    • Yes you may. For the West Coast Nationals and International Finals, the IDRC will be inviting out some of the most popular gourmet food trucks, so save some room for an awesome lunch.

    I bought my ticket online through the FOAT, what do I do now?

    We have a car crew and we are all thinking about coming out to race. Are there group discounts available?

    • If you are a first-time group coming out to race with at least six cars, we have special discounts available. Please contact thirashima@hardmediainc.com or call 714.593.0280 and ask for Tyler Hirashima for details.
  • RACER FAQs

    Does the IDRC make the safety rules?

    • Currently, IDRC events are held at only National Hot Rod Association (NHRA) member tracks. The NHRA establishes rules for every type of vehicle that can run down the quarter-mile at the member tracks. Each year, a new NHRA Rulebook is published with revisions and updates.

    I have a streetcar that I’m planning to race for the first time. What do I need to race on the drag strip?

    • Tires in good condition with all of the lug nuts on the wheels
    • Battery is secured by factory tie-down in stock location
    • The factory coolant-overflow tank is in place
    • The clutch/neutral safety switch is functioning (clutch must be pushed in to start the vehicle)
    • Factory seat belts and seats are in place.
    • Valid state-issued driver’s license
    • Shirt, shoes and pants. NO shorts, NO slippers, NO wifebeaters!
    • If your car is quicker than 14.00-seconds (13.99 or quicker), you will also need a helmet with the proper rating.

    What kind of helmet do I need if my car will run quicker than 14.0-seconds in the quarter mile. ?

    • Helmets must have a SNELL rating of 2005 or 2010, as well as those with an SFI rating of 31.1A, 31.2A, 41.1A, or 41.2A. (SNELL 2005 helmets expire on 1/1/2017 and SNELL 2010 helmets expire on 1/1/2022).

    Can I run a nitrous oxide system on my car?

    • Yes, unless the IDRC class runs forbid it. All, nitrous-oxide bottles must be vented to outside the driver compartment if it is mounted in the same compartment as the driver. If mounted in the trunk and separated from the driver compartment by a bulkhead, no blow-down tube is needed. All bottles must be stamped with a DOT – 1800 pound rating. The driver will also need to wear a jacket meeting the SFI 3.2A/1specification.

    I put on an aftermarket supercharger or turbocharger on my car, do I need any additional safety equipment?

    • If the car wasn’t originally equipped with a supercharger or turbocharger, the driver will need to wear SFI 3.2A/1 Jacket in vehicles equipped with non-OEM nitrous oxide, turbochargers or superchargers

    What do I need if I plan on running slicks?

    • Aftermarket axles of FWD and RWD vehicles is highly recommended at any performance level. A driveshaft loop is also required on RWD vehicles going 13.99-or quicker.

    Can I run my convertible?

    • Yes, but additional safety requirements are in place if there isn’t a hardtop installed. A roll bar and SFI approved harnesses are required when the vehicle is quicker than 13.49-seconds.

    Is that all the safety equipment I need for my street car?

    • NHRA requires increased safety equipment as the performance level of the vehicle is increased. The basics are as follows. A sound and solid car is good for 14.0s. That car with an approved helmet on street tires is good to 11.50-seconds (additional safety requirements are placed on vehicles running slicks). When a car goes 11.49-seconds or quicker, but slower than 10.00, here are the requirements:

    11.49 seconds (7.35 1/8th) 

    •  SFI 1.1 or 1.2 Flywheel / Clutch
    •  SFI 6.1, 6.2, 6.3 or 9.1 Flywheel shield
    •  SFI 3.2A/1 approved jacket
    •  Roll bar
    •  SFI approved seat belts
    •  Drive Line Loop with street tires
    •  Full Leathers on M/C, ATV and Snowmobile @ 120 MPH

    10.99 seconds (6.99 1/8th)

    •  SFI 4.1 Transmission Shield, or at 135 mph
    •  Locking transmission dipstick tube
    •  Aftermarket axles and axle retainers
    •  SFI Harmonic Balancer
    •  Roll Cage with altered floor pans, or 135 mph – Window net required
    •  Ignition cut-off on all bikes / snowmobiles that exceed 135 mph

    9.99 seconds (6.39 1/8th) or 135 mph 

    •  NHRA Chassis Certification
    •  NHRA Competition License
    •  SFI jacket & pants 3.2A/5
    •  SFI neck collar & gloves 3.3/1

    •  Full Face Helmet meeting Snell or SFI specifications

    150 mph

    How Many Qualifying Rounds will there be for the heads-up and index classes?

    • When the weather and car count allow, the schedule will be drafted to include THREE qualifying rounds. However, it is at the discretion of the IDRC Race Director to increase or decrease the number of rounds as conditions require.

    I like to pit far away from everyone and sometimes I can barely hear the announcements. What should I do?

    • We always recommend pitting next to competitors in the same class so more ears are listening to the same important instructions. If that is not an option, tune your stereo to the FM channel that broadcasts the PA announcements. This information can usually be found in your racer packet.

    What happened to the heads-up class that I used to run in? Will it be coming back? In what class should I race this year?

    • If there is no heads-up class for you, we highly suggest moving into one of our new index classes. In most cases, you’ll see many of the same racers that were in your previous class, now in the same index class. Best of all, higher participation in each class means a higher payout. Will your heads-up class ever come back? There is a good chance that the more popular ones will return once car counts are up to a level that supports the formation of a new class. However, some may just prefer the simplicity and the variety of competition in the index classes.

    My car is fast and I’m a great driver, how do I maximize my winnings?

    • There are two simple ways to maximize your winnings. First, get into a popular class. Higher car counts mean higher payouts for each class. Getting your friends to bring their cars is a great start. Second, run the proper contingency stickers. Read up on the contingency programs and get the decals on the car before you even make your first pass. There are thousands of dollars in cash and prizes that are available to racers in these programs.
  • Class Specific FAQs

    Are there any major changes in any of the competition classes this year?

    For 2015, the Garrett Pro FWD Class rules have been stripped down and simplified to increase participation. Here are the changes:

    •  Any turbo with an inducer up to 72.49mm can be used
    • There will be no weigh-ins for 2015
