Hey KM the server you emailed from is blocking my response email. So here goes.
Glad to here others are racing 1:24 Sprint Cars and Late Models. I’ve run on a track very similar to what you described. It is a fun track and can be flat out depending on the cars and voltage. A track that is flat will generally be tougher to drive, each have their pluses and minuses. What does the rest of your group want to do with the track? Don’t forget to consider what the group has to say. If your looking for more even competitive competition you might consider changing the voltage to the track or knocking down the voltage to the fast lanes, try to get all the lanes so a single car will do about the same time in each lane. Or you could Round Robin style races, that way everyone has to deal with the same track conditions through the course of a race. Hope this answers your question.
