Fidanza is world famous for the high quality lightweight aluminum flywheels we make. We are known to have the best quality and best selection of any flywheel manufacturer in the world, and we’re proud of that reputation, because we earned it!

Fidanza Performance (founded 1997) is the US based designer and manufacturer of the highest quality lightweight aluminum flywheels, precision adjustable cam gears and high-performance clutches in the world. With almost 20 years in the performance automotive market, Fidanza is still the best-known and most respected manufacturer of performance and racing flywheels around. With product offerings ranging from European performance, to hot Asian imports, or vintage racecars to modern day muscle cars, we’ve got you covered. Our company is recognized the world over as the premier choice for quality driveline parts and we want you to experience why.

Fidanza Performance had its origins in racing. Our original owner, Lou Fidanza, was the designer and builder of the famous #19 Grand Tourismo Jaguar that chocked up 11 consecutive SCCA national wins and went on to defeat Paul Newman’s factory backed Nissan 280ZX in the 1980 SCCA National Championships. That experience in building championship level cars led Lou to designing and manufacturing many of his own specialty parts, including aluminum flywheels. Starting with Jaguars, Lou’s many friends in the racing world came looking for that same expertise for their cars and soon Fidanza Engineering was born. Since its inception, Fidanza has engineered, manufactured and sold tens of thousands of flywheels around the world. Domestic, import, European to Asian, we’ve done them all. We’ve also participated in a myriad of events around the world and even been featured in popular video games like GRID, GRID II and DIRT just to name a few.

Over the years, our customers have grown to rely on our products, so when requests came in for us to provide them with other critical components, we put our expertise to work again to offer our customers top of the line parts like our Adjustable Cam gears and V-Series performance clutch kits for today’s performance automobiles too.

Hi There, I’m Jeff Jenkins, Owner and President of Fidanza Performance, and I’d like to welcome you to the Fidanza family! The Fidanza team has put together this website to tell you a little bit about our products and show you what goes into making our high performance, lightweight aluminum flywheels.So, why choose our aluminum flywheel versus stock steel? It’s simple: Our lightweight aluminum flywheels will give you faster, crisper throttle response, quicker acceleration, faster & smoother shifting, better braking from speed, reduced stress/wear on your engine and maybe even a little better fuel economy…if you can keep your foot out of it that is. Our flywheels are @ 40%-60% lighter than stock steel flywheels, and that significant reduction in rotational weight frees up horsepower that your engine would normally need to get that heavier stock flywheel spinning, and that provides additional “free” horsepower to your wheels. That same reduction in weight also makes it easier to slow your car down and will make it accelerate and brake as if it were @150-200 pounds lighter on average. Lighter rotational weight also means smoother clutch engagement and faster shifting. Ask any racer and the choice is clear! Even for drag racing, the lighter flywheel’s wheel horsepower advantage pays off, cutting a reported one to two tenths off the quarter mile. Of course it takes a little getting used to since an aluminum flywheel means you can launch at a little higher rpms without “shocking” the driveline and tires, and the lighter weight and faster acceleration means you’ll be shifting just a little sooner as you head for the traps! But in independent testing shown by both Popular Hot Rodding and Muscle Mustangs & Fast Fords, the advantage is clear, and lighter is better! So then, why choose Fidanza aluminum flywheels over the other guys? That’s simple too! Our flywheels are designed, engineered and manufactured right here in the USA. Our team doesn’t just take a stock flywheel and copy it out of aluminum like some others do. We actually analyze the originals and engineer improvements where needed; whether it be in overall balance, critical clearances or improved design, our flywheels are built for performance. Machined from the highest quality 6061 T6 or 2024 T3 aluminum, each flywheel is manufactured to deliver optimum tensile strength, heat dissipation and weight reduction, without going too light and causing poor idle and driving issues like some of the ultra-lightweight competitors. We aren’t always the lightest, but we are the best! All Fidanza aluminum flywheels also feature our replaceable friction surface eliminating the need for resurfacing or total flywheel replacement when changing out clutches, saving both time and money. Even the placement of our military spec hardware is engineered to minimize wear and maximize heat transfer and clutch engagement providing longer clutch life and better performance. Now that I’ve talked a little bit about our flywheels, let’s see how it all comes together…
