JR Dragster

Has anyone participated in junior dragster? My son, 8, has become stupidly obsessed with that sport and wants to give it a shot. Just looking at something to see if he truly has the itch so not looking to dump 20k on a new chassis and drivetrain…. Yet.

Tips?
Tips? The only tip I have is open your wallet. They won't let kids run junk down the track.
We fielded 2 Juniors and It ain't cheap.
