My I20 came with a zipper on the tramp that I suppose is for a spin bag. Is this stock, or an add on, and is it a good system for distance racing?

Yep, Your I20 was setup with a tramp spin bag at one time. Often they set them up to zip on and off. Unless you can find the exact same zipper you are going to be hard pressed to match it. Though it's definitely possible. Might be easier to find the old owner and find out where he had the bag made.
