Grip Equipped 3 Piece 2/19

7 With specs in hand, we called Grip Equipped for a custom set of 3-piece wheels. Forgeline Motorsports manufactures the wheels for Grip Equipped. This is the raw forging of 6061 T-6 aluminum that is to be the Rebel wheel’s center, which is forged on a 6,000-ton hydraulic press. At the very beginning of the process, designer Ben Hermance must decide if the wheel is to be a shallow, concave, or standard (convex) style. Then his design is put through Finite Element Analysis to ensure there are no weak points, and tested beyond SAE standards using a real-world load variable.

9 The CNC machine cuts the spokes out next. Just look at all the excess material left over! The weight savings in forged wheels is not only due to the material, but the machining as well. Best of all, there is no sacrifice to strength – these wheels should last the life of the car no matter how hard we run it.

Wheel Centers After 6/19

10 After the centers leave the CNC machine, there is an extensive deburring process in which they are sanded by hand and prepped for finishing. All this TLC really makes the difference.

11 Last but not least the outside lip and inside shell are assembled once they have gone through the finishing process, and then the centers can be joined using ARP hardware. If the wheels ever become damaged, they can be taken apart and serviced in the same manner rather than having to scrap the whole thing like with a cast wheel.

12 A-D. Voila! Here is the finished product. Not only are these wheels amazing to look at in pictures, but the little details are incredible from the hardware to the powdercoat and valve stems. And we’ll never have to worry about whether our cast wheels might crack and come apart at the track. For more information and pictures of the wheels being built, go to
