The guys at Road Race 1 are fantastic. Shawn and Nick are very knowledgeable on road course cars, especially the 79-04 Mustang chassis. Every order I have done with RR1 has involved some emails back and forth to help me decide what I needed for my particular application. And so far, after every recommendation and order, the car has gone faster or done better. Shawn and Nick aren't just part slingers or yet another online drop-shipper. They know and understand these cars because they go put them on racetracks and drive them harder than I ever could. I've also reached out with technical questions and gotten great help even when the conversation wasn't going to directly lead to a sale. I value that highly. I'm not saying you should blow them up with questions if you aren't ever gonna buy from them, but they will support you however they can if you treat them right. Highly recommend them to anyone and everyone!
