Unless something is severely under powered, I personally don't ever see the need to use the lower hole. I think it's better to get the bar as stiff as possible, as quickly as possible... and use the shock to control the hit.
GY3... when you say shock settings are at 7, do you mean 7 clicks from full tight? What front shocks do you have on it? In the 60ft range you're in, I would definitely move to the upper hole.
I suggest moving to the upper hole and continue to click the shocks tighter 2 clicks at a time. The car will pick up 60ft as you do it until it gets to a point where it spins. Then back them off 1 click. That will get you close...
From there it's a balance of rear shock setting and front shock setting to optimize further.
I am at two clicks from Full tight. I did 9 for a while which is the fully tight setting and it spun a little. My main problem is the track prep goes away quickly at a Friday night Grudge night because of all the super hard street tires pulling up the prep and the rubber. Going to get some hits in on a decent track in the next few months and we'll see what happens. Definitely going to try the top hole but probably won't get to it until next season.
