If it's your first race, I wouldn't worry too to much about your shock oil. Make sure everything is threadlocked and ready to run some decent length races. Charge up everything....double and triple check it all. My first outing was less than stellar. I had a wheel fall off...my motor mount twisted....fouled a plug....and my tranny refused to shift. Still not sure how I made it through the day....but hey.
Just go and have fun. Make sure the rig will stay together...and then start adjusting it later.
haha i was just thinking the same thing earlier about just waiting to get the shock oil.
and i hope to god it stays together lol. i wont be very fast at first but i hope atleast it stays together lol
