Introduction

Everything You Wanted to Know About NASA's American Iron Racing Series

The roar of a V8 at full throttle is irresistible, and it’s what gives the American Iron series so much of its character. The series enjoys a virtually unlimited supply of donor cars because it is open to any American-made sedan or coupe from 1960 forward, and the power-to-weight ratios keep things simple. Sandwiched between the wide-open rules structure of American Iron Extreme and the more limited Spec Iron series, American Iron provides racers a lot of room for creativity when building a car, and provides close competition on track. “Those older cars with the right driver can be just as competitive as the newer cars,” said Rob Capetz, series leader for the Southern California Region. “That’s the beauty of the power-to-weight ratio.”

The American Iron series was created to meet the needs of domestic sedan racers looking for a series specifically tailored to accommodate modified vehicles that are currently relegated to racing in Unlimited or Spec-limited series. This series is designed to field a large high-profile group of American muscle cars and will unify fields of cars that currently race in other sanctioning organizations. With this in mind, a variety of other sanctioning organization formats (such as standing starts and flying starts) may be employed during the regional racing season and at the National Championship. This large field/open modification concept will provide racers and vendors access to a promotional racing venue containing similarly prepared and appearing cars that can run nearly unlimited configurations.

All 1960 through present, American-made sedan vehicles/body styles certified by the United States Department of Transportation for street use at their date of manufacture. OEM and aftermarket “Body in White” type vehicle shells are allowed provided the body style is the same as original DOT manufacture.

Questions and Answers to Feed Your Curiosity

American Iron is a road race series that calls to mind the legendary pony car battles of the 1960s where Ford, Chevy and Dodge competed against one another to win stoplight and drive-in bragging rights for their brand of choice.
The American Iron Series consists of three classes: Spec Iron, American Iron and American Iron Extreme. SI offers racers running 2005-2010 Mustang GT’s an affordable “spec” build, with direct support from Ford Performance. The AI class is limited by a power-to-weight ratio and other important factors to keep the cars on an even playing field despite including nearly every pony car that has been produced in the United States since 1960. The AIX class is more “gonzo” with big horsepower, true racing slick tires, and much more liberal build rules that make the cars wide open from the green flag.
The best place to get started is the class rulebooks. Everything you need to know is contained in them.

In the back of each rulebook is a contact list for all series directors. Simply send us an email or give us a call.

This is still up for debate. Typically, lighter, less-horsepower cars work well at tracks with lots of turns and short straights while heavier, higher-horsepower cars work better on tracks with few turns and long straights.
Absolutely, however the Camaro and Challenger are not as popular as the Mustangs.
Friday is usually an optional practice or test day, while Saturday and Sunday normally have a practice, qualifying and race session each day.
Yes, races are run rain or shine.
Yes, we encourage you to come to an event, check out the cars and talk with the racers.

What American Iron Competitors Say

I like the power, the sound, the handling, the looks and the affordability, in that order. AI has enough power to easily bring the rear out, which adds another dimension to your driving that you don’t get with Miatas and E30s. It’s also not too high that components will start breaking. The sound of a small block V8, of course, is hard to beat. Sound is definitely part of the experience, so if you are going to spend the dough to race wheel to wheel, your car might as well sound wicked. With the proper components and chassis stiffness and setup, these cars are a joy to drive. My car will do what I ask and is easy to save if circumstances get a little hairy. I believe a nicely built AI car of any brand is a thing of beauty. Lastly, I believe AI has one of the best experience-to-affordability ratios. I mean, if a person rated the experience of driving an AI car on a scale of one to 10 compared to other cars and then did the same for the costs, I believe in most cases it would be hard to beat. Tires are affordable and last for two weekends on my car. I can go a whole season on one set of pads (thank you Baer!). If I pop a motor, I can get a new Coyote for under $6K.

I wanted to race an American built muscle car representative of the past. It’s all-American and can be seen on the streets. I like the torque, horsepower and sound of a large displacement V8 engine. No paddle shifters, just a stick shift and clutch requiring more driver input.

I love the V8 power and sound. I’m familiar with the cars, and they are easy to modify for racing. The rules have stayed consistent over the years. There’s great competition — even with very different cars! Great friends, too!
