What a good marketing idea, ask the customers what we want from you! Much appreciated and quite refreshing to see
My 2P is that a lot of kit cars are running engines and exhausts that were never designed to go in that application so some, especially the 7 owners, have components closer together than would be ideal. Others like myself, have problems such as running components in locations they were never designed for, i.e. mid-engined with a big Rover V8.
So i suppose that people would be interested in any of your product lines that would allow them to be "creative" and still allow them to have a reliable car.
Heat shields, heat wraps and all the modern and alternative options that are out there.
hope that helps your thinking?
