Steve York has been appointed as the new director of the ARCA Menards Series West, bringing decades of motorsports experience to the role. York has a diverse career background, including time at UPS and ownership of small businesses, but his passion has always been racing. In the 1980s, he founded Magic Valley Speedway, the 1/3-mile asphalt and 1/5-mile tri-oval in Twin Falls, Idaho, transforming a desert plot into a NASCAR-sanctioned track in under 60 days. It was an effort that helped earn him the Promoter of the Year award in 2005.

York's deep connections within the racing community, particularly on the West Coast, make him well-suited to lead the series.

Heyward Wagner is turning the venerable Sports Car Club of America into tomorrow's sports car sanctioning body.

The Sports Car Club of America was founded in 1944 by returning US servicemen. They created the club to celebrate their passion for the small, quick sports cars they had encountered in Europe. The diminutive MG, Triumph, and Jaguar cars formed the core of the membership's collection, and ownership of a sports car was required for membership.

Fast forward 81 years, and SCCA is now one of the country's most prolific motorsports sanctioning bodies. From the traditional sports car road racing to time trials, hill climbs, enduro racing, Track Night, autocross, rallycross, and road rallies, SCCA offers a menu of events like no other organization. The club also carries the weight of those 81 years of history. SCCA has gone through profound changes in its mission and orientation, from a purely amateur racing club to some of the most consequential professional racing series in history, including the Can-Am and Trans Am series, and Formula 5000.

Today, Heyward Wagner is the vice president of Experiential Programs for SCCA, but the title doesn't begin to describe what he does. Simply put, Wagner spends his days as SCCA's chief visionary, figuring out where the grassroots sports car enthusiast is headed, and developing the events that will bring those enthusiasts into SCCA as members and participants. Wagner is himself a second-generation SCCA member and racer, so he's been steeped in the culture all his life.

(Editor's note: In full disclosure, the interviewer is a second-generation SCCA member and formerly served on the club's Board of Directors.)

PRI: We're both second-generation SCCA people. How did your family find its way into this club?

Wagner: There's a bit of mythology that my conception may have been inspired by a track worker shortage in the late 1970s, but I've not been able to confirm that definitively [laughter]. My parents were heavily involved in flagging and communications throughout the 1960s and spent some time in Europe. They came back to the Atlanta area in 1970, just when Road Atlanta was opening. There was a big influx of folks who were interested in flagging because of the Can-Am race that had happened that year.

In that era, SCCA had a lot of disparate ways of doing things across the country. So when they started bringing drivers from all over the country together for the early National Championship Runoffs, they needed to have consistency in flagging and communications. My dad was the first national administrator for flagging and communications, and he and my mom together wrote the first flagging manual. I was born into that.

PRI: You didn't always work for SCCA, though. How did you come back to the club?

Wagner: I had been super involved in the club in my 20s. I was a corner captain at the Runoffs, and I was a Solo [Autocross] chair for the Atlanta Region. I was going to Solo Nationals every year and really chasing championships hard. I kind of reached a burnout point, from exhaustion, financial, everything. So I just picked up and went to the San Francisco Bay Area and got a job working for a ski and snowboarding store. That gave me ski passes to all the Tahoe resorts. Then in 2013 I was at Solo Nationals and ended up talking to John Walsh, who was the chairman of the board at the time. I sent him an email a couple of weeks later, where I laid out how I saw the club's focus on road racing as an elite activity, while the Solo Nationals had the message that everybody's welcome, and 10 times as many people were competing in Solo.

I ended up giving a presentation to the Board where I talked about my experiences in outdoor recreation. I talked about how summer camps and ski resorts and race tracks all have fences built around them. They all have one way in and one way out. You sign a waiver; you pay some money to get in. They're all completely elective activities, but race tracks are the only ones where people seem to leave being unhappy. People leave summer camps and ski resorts smiling, having had a good time. But race tracks, it seems like we send a lot of people home frustrated, upset, angry, bothered, about something they didn't like. That was really true of volunteers, and it was true of drivers.

Then I posed the question to them: What if we got as serious about recreation as we are about competition? What if we made room for the idea that you can have fun? I was actually hired on April Fool's Day 2014 with no job description, no title, no department, but with this idea that there was something experiential that I was going to chase after that would be fun.

PRI: You're introducing all kinds of new programs and new events, partnering with other sanctioning organizations. Why is this happening now?

Wagner: I think there's a lot of whys. One is that markets and desires change. The focus of interest in the 1960s, '70s, maybe even the '80s, was that winning was really important. So recreational competition was really in alignment with how we valued ourselves and our time as a nation. But I think that in this era, recreation for the sheer sake of enjoyment is far more common than recreation for competition.

There are some crystal-clear examples of that. I enjoy mountain biking. I live in the Asheville, North Carolina, area, and I wouldn't say that everybody I know rides mountain bikes, but a whole lot of them do. It's much more of an experience base than a competition base, so it's a pretty big shift in society. I think that for SCCA to be relevant, we need to respond to those shifts.

There's also a reality that 30, 40 years ago you couldn't get on a race track in the United States unless you were racing. There wasn't an opportunity to just go enjoy the drive. When there's only one pathway in, and as barrier heavy as racing is, a lot of people are just not going to make that effort.

Finally, SCCA is not the only way to get on a race track anymore. So for us to remain relevant in the marketplace, we need to sell things that are desirable to the marketplace. Racing can be that, but a track day, a time trial, something you can do in your everyday car, that's much more access friendly. We need to continue to recognize that these things are changing and fluid, and we need programs that represent the realities that we live in.

PRI: How did you come up with the experiential name, and what does an experiential event really mean?

Wagner: Experiential in the wider world refers to events, programs, and things where it's about the experience rather than the result. I really felt like that was what we needed. We needed to signal a different way of doing motorsport business, a different way of offering club activities.

To me, experiential means...

Aftermarket upgrades are available for popular tow vehicles that help maintain optimal temperatures and enhance suspension dynamics.

Racers have enough on their mind agonizing about track conditions, engine tune-up, chassis setup, the weather, and other key competition factors. Traveling to the track should be a stress-free affair. Tow vehicles that break down, struggle up mountain passes, overheat, or empty the wallet at the fuel pump are not giving drivers and teams the freedom to focus on the race.

Hauling a race car across a state or across the country is more than just navigating the map. It's about making the trip safely, efficiently, and with confidence. Heavy-duty pickup trucks from Ford, GM, and Ram in the 2500/3500/4500 classes are extremely well equipped for towing. But today's trailers are also heavier, with more payload capacity and comfort features. Sometimes, tow trucks need a little help to get the job done right.

"Manufacturers have good engineers. It's just that they're cost constrained," explained Joe Komaromi of Pacific Performance Engineering (PPE) in North Las Vegas, Nevada. "The trucks are already expensive. Manufacturers don't want trucks to cost $200,000 by putting the best of everything in them, right? We as aftermarket companies will actually engineer the best possible part for any given application. If a customer falls into that area, such as somebody who is towing heavy, then we have the parts for them. The guy who's just taking his truck down the street to the coffee shop won't have any benefit from a lot of the parts that we make."

Towing upgrades aren't meant to actually increase towing capacity. That's a number determined by the manufacturers with extensive SAE-approved tests. However, upgrades can improve ride quality and stability, engine performance, fuel efficiency, transmission performance, and overall durability—all of which will help racers reach the track on time and economically.

Staying Cool

Cooling is perhaps the top priority when upgrading a tow vehicle. Face the facts: Summers are getting hotter, especially if you're towing in the humid South or in the blistering desert heat of the western states. Sometimes the factory transmission cooler isn't adequate for towing extreme loads. On the flip side, sometimes the factory allows the transmission to run hot to thin out the ATF, thereby helping to improve fuel economy slightly.

"Now they're already at the upper temperature limits, and the transmission doesn't have any heat capacity left to accept additional torque during heavy throttle," said Komaromi. "We have products that will reduce the temperature, such as deeper, larger capacity transmission oil pans, thermostat bypass valves, and bigger transmission-fluid coolers."

A PPE air-to-water intercooler kit can lower transmission temperatures by as much as 50 degrees, according to Komaromi. The coolers are designed to fit in the factory location and use the factory fittings and hoses. A deeper transmission pan can lower fluid temperature up to 20 degrees.

"Your temperatures will be more consistent because you've got more oil and it takes longer to cool it," he added.

Transmission heat can also be controlled with a torque converter swap. Racers know the benefit of a higher-stall-speed converter that allows the engine to rev in the rpm range where it can make the best power. But high stall speeds create more heat.

"With a tow vehicle, a tighter low-stall converter is normally needed to keep driveline heat in check," said Krista Baldwin of FTI Performance in Deland, Florida. "Tow vehicles inherently have a lot higher load on the converter. This introduces more heat to the driveline, and this has to be adjusted for accordingly in the converter."

Fueling Innovation

Budget-minded racers might look for a used heavy-duty pickup, but there's always the potential that you're buying someone else's problems. Fuel-delivery problems on some Ford models prompted Fleece Performance in Pittsboro, Indiana, to develop a number of products that prevent leaks and improve filter performance.

"I call it a hardening product for the Ford fuel system," said Jeff Everett. "They work to address some of the weaknesses in the fuel system on the 6.7L Power Stroke, which is probably the biggest audience of towing vehicles for guys going to the track."

Heat and vibration under the hood can deteriorate plastic fittings, so Fleece developed billet aluminum return-line fittings for 2011–2024 models. These fittings include a dual O-ring internal design for increased sealing. Fleece also offers a drop-in replacement for the plastic under-hood filter assembly. The new Fleece version features a billet aluminum cap and billet-aluminum quick-disconnect fittings. There's also an under-bed filter-replacement kit that allows conversion to a more convenient and less expensive spin-on filter. The Fleece model is also capable of adding a fuel heater for cold climates.

"Our goal was to remove all of the plastic interconnections that are exposed to heat and vibration and are prone to cracking and breaking," added Everett. "All the pieces go together; it just depends on the model year. It really is like a hardening of the fuel system to make it more reliable."

Speaking of the fuel system, Hot Shot's Secret in Mt. Gilead, Ohio, recommends its Everyday Diesel Treatment (EDT) to help improve fuel economy, help keep injectors lubricated, and resist corrosion during long periods of storage.

"When you're towing a race car, fuel economy and reliability are everything," said Joshua Steinmetz. "EDT gives you more pulling power, increased fuel economy, and peace of mind knowing the fuel system is protected. EDT oftentimes pays for itself in fuel savings alone. Then add the injector cleaner, lubricity boost, fuel stabilizer, and water demulsifier, and it's like insurance for your fuel system."

Suspension Upgrades

Towing heaving loads can strain a truck's suspension, possibly compromising vehicle handling and the way the trailer tracks. A number of aftermarket companies have developed products to modify the suspension to improve ride and handling characteristics...

As cars from the 2000s move into vintage classes, sanctioning bodies are noticing that fanbases are starting to expand.

For every generation, the word "vintage" conjures up different images. For a young racing fan, a vintage car might be one remembered from childhood only 15 years ago. For that fan's gray-haired uncle, it seems like only yesterday that same car was the newest, hottest thing.

Vintage sports car racing has to walk a fine line between what its most ardent fans consider vintage, and what will attract the next generation to come through the gate. This balancing act is not a new issue. Vintage Racer Group (VRG), a Mid-Atlantic based organization established in 2004, was chartered in part to address the shortage of opportunities for cars of "in-between" years to race.

Paul King, a VRG board member and event chairman of VRG's Lime Rock Labor Day race, was building a 1972 Triumph GT6 in the early 2000s and was frustrated with the lack of racing options for his car.

"At the time, we literally had no place to race it in the Northeast other than the SVRA events, because the VSCCA [Vintage Sports Car Club of America], which was the dominant vintage club up there, I think they were probably limited to 1962 even back at that point," King recalled. "A very dear friend of mine I had started going to car shows with, he was doing VSCCA vintage racing. There was a group of VSCCA members who started VRG in 2004. It literally did start for two basic reasons. A lot of the individuals who were involved with starting the club knew there was a lot of demand for an organization that would allow newer cars. And at the same time, better safety standards."

Today the VRG holds its own events as well as teaming with other vintage organizations for joint ventures. And just like in the beginning, the definition of vintage is rolling forward. VRG rules allow Sports and GT cars and select sedans on sale to the public on or before January 1, 1989, and Improved Touring cars through 1993. But special exhibits and flexibility on some rules have brought in newer vehicles that have turned heads with a new generation.

At Lime Rock Park's 2024 Historic Festival, which VRG co-sanctions with VSCCA, turn-of-the-21st-century World Challenge cars were featured. "The ideas behind the World Challenge were basically street stock race cars from 1995–2005 prepared for the SCCA World Challenge, as well as the Motorola Cup and international categories like the ITSA, Super Touring, JDTC, previous Escort Endurance, IMSA Firehawk. It encompasses a lot of cars. It was a big experiment. We worked really hard," King said. "I saw the reactions of the fans, of the spectators, when those cars were out on the track, and they were a big hit. So we know that we're onto something, and we're continuing it this year."
 

New Cars, New Faces

Historic Sportscar Racing (HSR) in Daytona Beach, Florida, was founded in 1977. Now under the IMSA umbrella, the organization has accommodated traditional vintage race cars while simultaneously finding a home for more recent cars that have aged out of current IMSA classes. That pipeline has allowed for a steady stream of fresh faces at HSR events.

"This year at the Classic 12 Hour at Sebring I think there were six DPis, Daytona Prototype International, that were running in HSR at that event," said John Doonan, president of both IMSA and HSR. "The homologation for those cars ended in 2022. Three years ago, they were racing in IMSA. So I think there is that pipeline, but I think it's a proper balance between what is considered vintage or historic and modern era stuff. I think making sure we maintain a balance is important.

"Take the Acura NSX for example," Doonan continued. "That car ended its homologation as a GT3 car in IMSA last October at Petit Le Mans. Now, those private owners who bought those cars want to have a place to race. I think there's this really important balance between what someone may call vintage or historic, and modern-era cars that are now not eligible to race."

HSR has also launched a NASCAR Classic class, popular among both participants and fans...
