It's easy for a paint shop to match a standard paint finish when they can pull the code off the strut tower. I don't know how it would work with an individual color.
And anyone who thinks Jet Black will hide swirls is GRAVELY mistaken.
Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
