COMMUNITY
Our industry has been in the spotlight recently concerning global warming, regulations, and more restrictive selling standards. With millions of individuals and professionals in the classic car, drag racing, and truck industries we know how important these passions can be. At the same time, as a business we feel we need to do our part for our community and the world for that matter. Therefore every year Speed Engineering contributes to our local Police Department, is a proud 911 Memorial Support Member, and purchases thousands of dollars worth of carbon credit offsets from a variety of solar, wind, and industrial industries. We are happy to do our part, and can only hope that our industry will remain a long lived passionate one for all the automotive enthusiasts out there.
