Fidanza is a company out of Ohio. I can speak from direct experience because they made some adjustable cam sprockets for the 2.3 that I used to sell....I say "used to" because I discontinued them because of a serious decrease in quality from the first batch I had bought from them. At first they were pretty good...not great and nowhere near as nice as Race Engineering sprockets but the price was less too....then the next batch I received was VERY poor...you could not even see the timing mark without straining your eyes and then you still had a hard time and they where not machined cleanly enough which forced me to spend another hour per part to buff and clean edges so that it was actually adjustable once installed. Because of this I stopped selling them.

As far as their flywheels go....I used to carry Mueller aluminum flywheels and have one in my SVO and the Evolution SVO...quality was outstanding but due to a death the company shut down. While I sold Mueller a rep from Fidanza was always trying to get me to buy their flywheels....doing some research I found that their flywheels were not as thick as some others which can lead to a problem on a flywheel due to the nature of its useage(warping, etc) and the quality was nowhere near that of what I was used to. I would not sell them for the 2.3 for that reason and that I already had a better product.

I can't speak from a 5.0 point on their flywheels because I have not used one...Fidanza is who supplies SPEC with all their aluminum flywheels. The friction area must be removable because the flywheel is aluminum and the friction area is steel...this is good because you can replace it if necessary without having to buy another flywheel.

As far as bolt on weights....provided the fastening hardware is of good quality there should be no problem with the weights.
