First thing you need to do is work out if it's too much front lateral grip or not enough rear .... more tricky than it might seem at first.
Easiest way is to stiffen the front springs and see if that helps ..... although it is likely to dull the cars response and make it kick it's nose up over the bumps but try to ignor that for now .... does it cure the spin outs? If it does your probably too soft all round ..... try that next.
Once you have the springs somewhere near then work on the oils to correctly damp the springs.
Once you have that then start to wrok on the link positions.
Forgot to mention that I normally do this process with the upper shock position in the middle hole (inside of middle 2 if a 4 hole tower) and the lower mount (wishbone) out on carpet ... in on rough surfaces or dirt.
If you can work out what the car is doing on corner entry -- mid corner -- and exit along with posting your set-up we might be able to point you in the direction of an improvement.
On the whole the order of set-up changes (most effect to least) are
tires
springs
oils
links
shock positions
castor
wheelbase
Get the tires and the shocks right and your a long way towards a result ... I think of the other adjustments as a fine tunning aid.
A couple of people expressed concern to see the whole front end of my RB5 in pieces between the first two rounds at a recent indoor event ...... some felt I may be making too many adjustments at once .... the following round the car went TQ ....
