Video of my first time to the track 71 Valiant 416 4spd

You will need to get some good adjustable shocks at minimum for the back. Lots of suspension tuning to play with there. It's got a lot left in it. You can probably tighten the clutch a little too. Have you tried doing a parctice launch on clean dry asphalt and reading the tire tracks? Have you scaled the car yet (I mean all four corners)?
