i must be completely missing something ?!?

need a lower axle ratio, maybe ditch the tunnelram.
in the video the car appears soft.
I just went from a 355 track lock to 410 spool. Sorry the tunnel ram must stay. I'm sure the car would be quicker without a 4 speed or tunnel ram but that's what makes me happy and that's ultimately what the car is for. Thank you for your ideas
