Hey Frank, I wanted to weigh in on this subject if I may. I wanted to share some of the advantages of a true forged 3 piece wheel.
1. All of parts are made from 6061 aluminum heat treated to T6 specs which is used widely in the aerospace community. A majority of other manufactures both multi-piece and one piece wheels use a softer, non heat treated alloy.
2. Since this alloy is stronger, we can use a much thinner rim, decreasing the weight at the outermost part of the wheel, where it affects the inertia the most. We also take the time to machine out 40 spots in between each bolt hole to add to this effect.
3. Maximizing offset and width is easy with Forgeline 3-piece wheels. Whether you are building a professional race car or a super exotic G-Machine, you want to build a wheel that will fit exactly the way you designed it to. We have over 150 different rim shell sizes in stock from 17x1.0 all the way to 20x10 and everything in between. So, chances are we can build exactly what you need, with out welding or cutting or modifying the original spun rim halves.
4. Our wheels are also easily customizable. Since the inner rim half, center, and outer rim half all start out as independent pieces we can finish them separately without tape lines.
5. Another major feature of our 3-piece wheels is the reparability, and the ability to change the wheels as you change your vehicle. If you decide to widen the fenders or change tire sizes, you can swap out your rim shells for a fraction of the cost of a new wheel.
6. All of the parts going into a wheel will be spun and checked for trueness before assembly as well as after assembly as a completed wheel. This insures that every wheel we manufacture will be as close to perfectly round as possible, reducing the need for excess wheel weights.
Forgeline started out as a 2-piece wheel company and made welded 2 piece wheels for over 10 years. As tires and suspensions evolved over the years, we found that our 2 piece wheels did not hold up as well as our 3-piece, especially on the track. And about 5 years ago we made a conscious decision to make strictly 3-piece wheels based on the fact we could make a better product and have a lot more versatility. That does not mean 2 piece, or for that matter, any other type of wheel is unsafe or does not have place in the automotive community. I am just saying, based the large amounts of information over the years, we believe that a 3-piece wheel is the lightest, strongest and most versatile product we can make. And frankly, that is what we are all about.
