Fidanza 66-72 Triumph GT6 Aluminum Flywheel

If you're looking to get more pep out of your 1966-1972 Triumph GT6, swapping to a lighter flywheel like this one from Fidanza can make a notable difference. A flywheel's job is to store rotational energy, smoothing out the power pulses from the engine and providing a consistent mass for the clutch to engage with. However, a heavier stock flywheel also acts like a brake, slowing down your engine's ability to rev up quickly. By reducing that mass, this aluminum flywheel lets your engine spin up and down much faster, which translates to quicker acceleration and a more responsive feel when you get on the gas.

Fidanza is known for making well-built aluminum flywheels, and this one is no exception. It's made from high-grade aluminum, which keeps the weight down significantly compared to a stock cast iron unit. This not only helps with acceleration but also reduces the overall weight of your drivetrain. The friction surface is typically a replaceable steel insert, which is a smart design choice because it means you don't have to replace the entire aluminum flywheel when the clutch wears out. Just swap the steel ring, and you're good to go for many more miles.

When installing a lighter flywheel, it's important to remember that the engine might feel a bit less smooth at idle, and you'll need to be a little more deliberate with your throttle input when starting from a stop. However, for many drivers, the improved acceleration and quicker engine response are well worth the minor adjustments. Make sure to check the manufacturer's installation instructions for any specific torque requirements or break-in procedures.
