Just follow the simple rule - "slide the front, stick the rear", and you will be fine. Get the rear end planted, and then slowly work towards increasing front grip to find a balance.
I set the F&R dampers on 1:2 ratio. Same oil in all, with 1 hole piston up front and 2 holes piston back rear; or same piston all round, with 60-F & 30-R... This permit me to run same tires on all corners. Very convenience when choosing tires!!

I do notice on dusty track, it spin out very very easily... So my latest RC inventories: 2 brooms(you can always find extra hands on track to chip in...) to swept the track....

I'm running it on carpet in a month, but have no time to practice at the track till the event.. Just want to be prepared.
When I was running my M04 on NiMh's, I had the balance set perfectly. Switching to lipos required me to add weight to meet our 1200g minimum, so I added small amounts of lead to keep the original weight distribution that the car had with round cells. It was lighter overall, but with the same balance the handling characteristics weren't changed.
