Hey V10, Sorry it took me so long to answer your question but I just got back from Dodge City last night. For the beginner/ sportsman class it is a Mod class, your cars will be fine. I had a good time in Dodge City and really like the facility at Raceway Park. After talking with the facilities manager there and checking out the facility, I built a pretty decent sized Off-Road Track AND we laid the base down for a dirt oval! I will be flying back out on Weds night and finishing things up on thursday and Friday. I look forward to seeing you then. I never posted pics on here, I'm going to give it a try and hope it works!
