Products That Caught Our Eye at PRI 2025
The 2025 PRI Show in Indianapolis was a full-throttle showcase of performance automotive products, from street-ready upgrades to extreme race tech. We hit the floor to highlight the booths, parts, and builds that really stood out—gear that makes engines breathe better, weld stronger, and deliver reliable horsepower with precision.

Two-Hour Tech
Improving your S197 Mustang doesn’t have to be an arduous affair. You’re supposed to enjoy working on your car, RATHER than dreading getting off work because you “have” to wrench on the Ford. With that attitude in mind, we recently spoke with Al Kamhi, of Control Freak suspensions, to get his advice on what enthusiasts could do to further the concept of upgrading a Mustang in just an hour or two. But there’s a catch: the upgrade had to make a real difference in the car’s performance.

The Cold Facts
Typically, winter isn’t the time of year when we are thinking about a car’s air-conditioning system…or is it? It’s understandable that we would tend to think about “fixing” the A/C during the dog days of summer, July or August, but once the car is put up for the winter, those hot and humid days are often forgotten. And short of those comfortable windows-down driving months, when we first pull out the car again for the next season, it’s smart to think about giving the A/C system the attention it needs. So, we think this is a great time to present to you troubleshooting highlights so that you can rip into the car and upgrade the necessary areas before the cycle continues.

SMOKIN’ SS – Part 3
Fabricating Custom Suspension Components
In a hobby where obtaining custom suspension pieces or a complete new tubular frame/chassis is as simple as picking up the phone, there are those enthusiasts who prefer a more hands-on role in the completion of such upgrades, which, of course, can mean many things to many people. Some simply want to be more a part of obtaining the parts they need, while others want to make every part exactly the way they want.
So how is a person to know which aftermarket parts are overbuilt and which are not, or to what extent a person should go as far as modifications are concerned? Admittedly, there are no easy answers to any of these questions, aside from considering the reputation of the companies building such parts, the quality of the parts themselves and the experience a person has to determine to what extent an upgrade should be taken.
Mark Davis of the Metalcraft Tools SkillCenter encourages his students to make their parts and build them in the configuration they desire. That is how he handled the suspension fabrication on the Smokin’ SS project Monte Carlo. But in the case of your own project, with all the aftermarket components available in the suspension department, why would you go to all this trouble to build nearly every component under the car? For the average tuner, this kind of fabrication isn’t feasible, but Davis puts his students through the paces of a real-world fab shop.
For Davis, he first laid out the specifics, and then his students designed, fabricated and assembled nearly every suspension component on the car. Here’s Mark Davis’ take on his students’ own project, and what he has to say about building parts:
“The Smokin’ SS chassis is about performance. So, rather than tweak on 20-year-old technology, we chose to design a versatile chassis with a multitude of combinations that will allow us to tune the Smokin’ SS for any challenge. From AFCO double-adjustable shocks to strategically placed weight boxes, the chassis has built-in adjustability. Specially designed component slugs allow us to change caster, camber, ackerman, anti-dive, roll centers front and rear, pinion angle, wheel-base lead and track-bar heights. With static weight boxes located throughout the car, 40-pound blocks of tungsten can be shifted front to rear, right to left, so fine-tuning the chassis to perform on any surface or under any adverse condition is easy. Tire footprint can be optimized with a simple turn of a wrench, taking even the best of drivers to their limits. The ‘blacktop dyno’ will set the marks and our ‘zero to fear’ chassis will erase them.”
Obviously, Davis has confidence in the Metalcraft Tools SkillCenter students and realizes the potential of this Monte Carlo project. It will be versatile in many aspects and a tremendous learning platform for the students. The custom suspension system is a key factor in the build, allowing for complete adjustability—adapting to the dragstrip, oval track and autocross. These simple adjustments will require different front/rear weight balances for each venue. Even the folks at AFCO see the value in such an exercise, offering to send a couple of shock technicians to re-valve the shocks and swap out springs if necessary. While the Smokin’ SS project is far from that point in its journey, it won’t be long until Davis and his team of students take their Monte Carlo for that first trip around the block.
Look for the next installment of this unique project as the students at the Metalcraft Tools SkillCenter fabricate custom seats, set up the pedals and install the brake system. For now, check out the awesome suspension under the Smokin’ SS and see how it all came together.
