Count on our experienced trackside support team to keep your vehicle performing at its best during races.

When the green flag drops, there’s no time for second-guessing. You need a team that already knows your car, knows the circuit, and knows exactly what needs to happen to get you through the weekend in one piece, ideally on the podium.
That’s what we do at ACI Motorsports. We’re a professional Porsche and GT race team headquartered in Chattanooga, Tennessee, with operations at Road Atlanta in Georgia, and we’ve spent years in the paddocks of Porsche Carrera Cup North America, SRO Pirelli GT4 America, and the SRO Fanatec GT World Challenge America. When you race with us, our trackside team comes with you, every round, every weekend, all season long.
Trackside support is exactly what it sounds like: having a skilled, experienced crew right there at the circuit, ready to handle everything your car needs from the moment you roll out of the trailer to the moment the race is over.
It matters more than most drivers realize until they’ve experienced it firsthand. When your team already knows how your car behaves, what your driving style demands, and what changes will actually make a difference, you stop spending your weekend firefighting and start focusing on driving. That shift in how a race weekend feels, and how it results, is huge.
For amateur and gentleman drivers stepping into competitive GT or Porsche racing, a capable trackside crew is often the biggest single factor that separates a clean, confident weekend from a stressful, frustrating one.
We’re with you for everything across the race weekend, not just the headline moments. Here’s what that looks like in practice:
Before you ever strap yourself in, our crew has already gone through the car thoroughly. Suspension, alignment, tire pressures, brake bias, all of it gets attention so that when you hit the circuit for your first practice session, the car feels right from the off rather than something you’re fighting to find.
When you’re out there racing, our guys are fully prepared on the wall. Scheduled pit stops, tire changes, quick mechanical diagnosis if something unexpected crops up, we move fast and we move accurately. We know the pit procedures and regulations of every series we compete in, so there’s no hesitation and no wasted time.
Your ACI engineer is talking to you throughout the race. Lap data, track position, tire info, strategic calls, we keep you informed and help you make the right decisions in real time, whether that means pushing hard or protecting what you’ve got.
Between practice, qualifying, and the race, we go through your data and talk through what it’s telling us. Where are you losing time? Where is the car working well? We make it straightforward, act on it quickly, and send you back out with a better-prepared car and a clearer picture of what to focus on.
The debrief matters. Once the race is done, we sit down together, go through the weekend honestly, and figure out what we build on heading into the next round. It’s one of the most valuable parts of the process, and it’s something we take seriously.
The quality of your trackside crew makes a real difference to how your race weekend goes. At ACI, you get the same experienced mechanics and engineers at every single event, people who know your car inside and out and who you’ve built a working relationship with over the course of the season.
That consistency isn’t something you can put a number on easily, but every driver who’s experienced it will tell you it changes everything. There’s less time spent re-explaining, less adjustment needed, and a lot more trust on both sides. You walk into the paddock knowing exactly who’s got your back.
We support drivers across some of the most competitive GT and Porsche series in North America. Here’s where you’ll find us:
Porsche Carrera Cup North America - One of the most respected single-make series on the continent. Identical cars, high-caliber competition, and a championship worth fighting for. Our team has extensive experience running 911 GT3 Cup cars in Carrera Cup and understands what it takes to stay competitive throughout a full season.
Porsche Sprint Challenge North America - A brilliant series for drivers building toward higher-level Porsche competition. We provide full trackside support for Sprint Challenge competitors on both the 718 Cayman GT4 CS and 911 GT3 Cup platforms.
SRO Pirelli GT4 America - Close, hard-fought GT4 racing that punishes mistakes and rewards preparation. Our trackside team is experienced with GT4 machinery and set up to deliver the kind of quick, precise support that this level of competition demands.
SRO Fanatec GT World Challenge America - For drivers at the top end of North American GT racing, the technical and strategic demands go up considerably. Our engineers have the experience to match.
The thing our drivers often mention first when they talk about racing with ACI isn’t the technical side; it’s how the whole weekend feels. You’re not a client being managed. You’re part of the team.
We talk openly, we plan together, and when something isn’t working, we say so and fix it. Everyone in the paddock is pointed in the same direction, toward getting you the best result possible, and that alignment makes a real difference when the pressure is on.
From the moment your car arrives at the circuit to the moment it goes back on the trailer, you have the full focus of the ACI crew. That’s what we think trackside support should look like, and it’s what we show up with every weekend.
You’ve put serious time, effort, and investment into your racing. The team behind you should match that.
