Just wanted to share the availability of my growing collection of magnetic ID number sheets. Check the SCCA Compliant section for magnetic sheets for your specific racing class. I will be growing the collection regulary. They are cost effective, reusable over and over, and are made of very high quality materials. Numbers/letters can be cut out and stuck to the class panels or to the car directly.
