I have two dirt tracks with in 25 miles of me here in Jonesboro Arkansas.
Street stock is the class that is fun, But the coil spring cars do a better job getting a round the track then our tortion bar cars do.
If you go to hobby class you can do more up grades.
I did the oval track in a 73 barracuda for one year and went to a nova and
parts and modes are everywhere for less money.
We had a guy show up here last year and shocked a few hobby x brand and took 3rd in his feature race.
But !!! it is a money pit ,But nothing can replace it when the bug bites.
My son races every week end. he is a great driver like I was!!hehe . He can get a car around a track very good and make smart moves and drives for many different people. here is a picture that I took last year when my son won the feature race when he drove the other mans car.
Then picture of me in a dart that showed up and I had to jump in for a picture.
The sons msa last years car and know he races his own street stock awaiting his supper modify car to get finished. the 23 car was my older sons car and the last picture red and black X brand is my younger sons hobby car he has on the track know last week end he took 2 in his heat and 4th in the feature race.
Good luck and enjoy, Nothing can be more fun then racing on a pile of dirt with others.
