Craig,
I would not be worried to much about other kit suppliers using donor parts.
Your cars and components are far superior to even the parts that donor cars offer up....
Additionally, the option to have a kit as you supply that fits together with little input and work by a purchaser is a real bonus. Not to mention the quality and appearance of a chassis and suspension that looks like it belongs together.
Other suppliers will need to lift their game or fade out. As you highlighted FFR under the Smith boys have realized this and taken their product to the next level - as you have done.
Again well done by lifting the bar. I am sure that other suppliers will step up and look at R and D and improve to all of our benefit.
