Just what exactly is a USRA B Modified (B Mod)? Find out the underpinnings of one of the most popular and competitive classes of racecar in the Midwest.
Thanks man I have asked guys at the track that race modifieds the difference and they could only tell me their track rules for there mod and told me to check the track I want to race at has kept me from buying one, and I asked A mod B mod and Ump mod, track I like Wilmont Wisconsin has open motor I think A mod but steel heads only why not just be Ump then so a guy can run big shows and be competitive I thought the class was to avoid the B/S and make it more affordable but this is racing guys spending 20 grand on an engine to win 500 lol
