The best thing that any of us can do to support grass-roots rally racers is to let the sponsors know. Buy a case of IYSK wine. Put a Renazco seat on your bike or buy something from renazcoracing. Find out who sponsors the riders you are following. Good stuff anyway. Then send them an email and let them know why you spent your money. These companies are involved mainly because they are also fans. But, if they see an actual return on investment, they'll keep doing it. Word gets around and sponsors beget more sponsors. Who knows, maybe someday one of them will help pay some of your rally expenses too!
