All the big money races around here and down south are 1/8th mile. Our track does an 1/8th mile and 1/4 mile series and the 1/8th mile series has atleast 1.5 times more cars. Its easier on equipment, the program runs quicker, when something does happens the clean ups are shorter. Some people like the 1/4 for the extra speed, I prefer the 1/8th because you get to glance at your opponent once and have to make a decision off your gut for the finish line without time to think about it..over thinking - the best way to loose lost of races
