Where do I buy/make time attack. I am looking for lime green. I want to paint my wheels black with a lime green ring. Any suggestions thank you

Most times time attack wheels are black with red stripe

you can buy a wheel then powercoat it or paint it to your own color scheme

find a wheel painter or finisher like-
