FORMULA 43 is a dedicated manufacturer of aftermarket automotive wheels. Using decades of experience with modular and mono-block wheel manufacturing in the automotive wheel industry, Formula 43 is able to produce the highest level of custom modular wheels for pro-racing, modern sports cars and Pro-Touring applications. FORMULA 43 is able to offer the latest 21st century wheel designs that feature new exclusive updates which result in improved strength, stiffness and weight savings.
The company manufactures wheels of forged aluminum using various methods and equipment from rim spinning to flow forming. Located in Michigan, FORMULA 43 works with many exotic sport car tuners and Pro-Race teams around the world.

What is our Formula? It's a specific "Spin-Form" method for 2 & 3-piece modular wheel rim-halves where "4" is the number of rollers on the German spinning machine used to form the rim barrel from a round flat sheet of 6061 aluminum. The number "3" represents the process of (1) spinning the part, heat treating/aging and (3) calibration. This exclusive process is known as, "FORMULA 43".


Formula 43 modular wheel center sections use a Rotary Forged process that results in a superior tighter, circular grain structure. The rotary forged center section begins life as a cylinder of billet. The billet is then heated and placed into a die in the rotary forging machine. The die spins the billet at 300 RPM while the billet is pressed from above at a 5 degree angle. The material then flows in a circular pattern into the die. The new forging is then heat treated, quenched and aged to T6 standards. The end result is a rotary forged center section that has stiffer spoke dimensions, lighter weight and a quicker moment of inertia.
Formula 43 Spin-Form
The Spin-Form process developed by Formula 43 is a specific method in spinning 6061 aluminum circular sheets into 2 piece rim-halves. The computer controlled German spinning machine uses four rollers to form the inner and outer rim-halves on tooling designed in the shape of each rim-half. The Formula 43 method is a three step process:



(1) spinning the part.
(2) heating and aging the 6061 rims to T6 condition and
(3) re-calibrating the rim-half after heat treating to ensure a very low run-out of the part.
Along with the Formula 43 process, several changes to the rims have been made to better fit and perform with today's modern racing and sports cars:
1. Improved safety bead on both inner and outer rims to ensure proper seating of the tire so that the tire will stay mounted to the rim in the event of impact or loss of air pressure.
2. Improved rim contour to help ease tire mounting and bead seating.
3. Added material in specific areas of the rim-half for additional strength and stiffness.
4. Drop center contour updated for proper TPMS fitment and installation without having to add additional brackets or modifications.
