I have tried the small tire Nitrous heads up deal .Cost way more than I can afford.Lots of fun and One crazy ride .
The car is fast but does not go rounds in a bracket.
I am building a faster light weight N/A big tire car.
Guess what . the N/A car is a lot easier and cheaper to build and run.
Not knocking either, but for me Brackets are in the future and the light big tire car is it.
Now for a wild ride a couple of times a year I will go with the Nitrous car.
