piston, spring or oil?
Starting with a good base set up on any car, I'm curious what action should be taken in the following scenarios.
1) track starts blowing out and punching it down the straight is resulting in the tire not being able to track the ground causing the wheel spin and engine over rev.
If I go lighter on the oil, the car will bottom out everywhere. Will more holes in the piston with lighter oil allow the tire to track the ground and not bottom on jumps?
2) car is good everywhere, but bottoms out on jumps.
Thicker oil or more holes in the pistons or springs too?
3) car is good everywhere, but the rhythm section causes the rear to chassis slap and ricochet way up and the car consequently loses time and wants to get sideways no matter how straight I enter. The spacing of the humps doesn't allow for doubling or tripling etc.

Hello,
No expert but I'd say :
1) oil is too thick / piston holes total area not big enough
2) Not enough packing on the pistons (need smaller holes but more of them)
3) The front/rear shocks aren't balanced the rear might have too soft springs. If the front is too thick/hard it will not absorb enough energy hence the back has to take it all.
Just with these info I'd say reduce oil viscosity a little perhaps and put a piston with more holes but a smaller holes diameters and probably try to either soften the front or harden the rear spring. So I agree with your suggestion with the added idea of smaller holes.
I think other will help you more but it might help to give these infos :
-car ?
-oils used ?
-piston used ?
-spring used ?
-and perhaps shock position on the towers/arms
