Those were the RCCA latemodels from the early to mid 90's same with the Sprint Cars. I just did a stop motion of the late models on that track 5 lap race which took 4 hours to set it up to watch 35-40 seconds worth of latemodel racing but it was worth it to watch. Unfortunatley My Slot car track will be going up shortly. To do some winter racing. Maybe I'll do something in the Spring with real dirt.
