FPS was founded after WWII under a different name, specializing in earth-moving equipment and tractors; its success allowed the company to experiment with aluminum wheels in the latter half of the 1960s, finally coming to market with a number of designs in the early '70s. A dedicated wheel foundry in Dello, in the province of Brescia, was ground zero for the new brand of wheels: Two other facilities, one in Sarezzo and one in Gervasio, were built soon after.



Every wheel mold pumps out a number of prototypes, which are subjected to rigorous testing and analysis before release. Chill-casting and counterpressure methods are used, depending on a number of factors, and every wheel is also X-rayed for possible casting defects. ''Each wheel is a special case,'' states period literature, ''based on two factors: styling design and manufacturing technology.'' Their production methods are exacting, and their testing methodology meets SAE J.175, with a 1,000kg weight dropped onto the wheel without the center breaking away or distorting to allow air to leak from the tire for 30 seconds. Other tests include bending moment rotating fatigue, a rim-rolling test, rim impact, and rim static deformation. And, of course, there's a visual inspection too. Once the prototypes are okayed, one wheel out of every 5,000 is pulled off the line and checked to make sure that it's up to the standards of the prototype. A fully automated paint shop, one of the first in the industry, contained multiple air purification systems, so that the environment would not be contaminated.


By the mid-1980s, FPS production had quintupled, and OE applications included brands as diverse as Alfa Romeo, BMW, Citroën, Ferrari, Ford, Innocenti/Mini, Lancia, Peugeot and Porsche (914)--among others. Even tiremaker Pirelli had a wheel made for it, which ended up on the Ritmo Abarth 2000 in the mid-'80s. The FPS initials appear within a diamond-shaped box with the horizontal edges rounded.


A Manilla-based joint-venture factory was opened in the mid-1970s, and by the mid-1980s, this had become Rota wheels, one of the top aftermarket wheel companies among the tuner and racing sets, and making 50,000 wheels a month for OE and aftermarket applications.

1968 BMW 2800CS riding on unusually elegant alloy wheels featuring a polished chrome centre cap discreetly concealing the mounting lugs. Visible fasteners on a contemporary automobile are generally considered to represent a lack of refinement, yet seem to be embraced when they appear on otherwise highly stylized wheels. These were produced for BMW in Italy by FPS (Foundry Pedrini Siena).
 
Just so you know, both FPS and Vial made an aftermarket alternative to the actual Alpina CSL wheel during that period. FPS and Alpina are not related, and these are not actual Alpina wheels, regardless of the fact that they have "Alpina" on them.
