Bene, bene....
Interessante il consiglio di Rune a proposito del preload sulle molle anteriori, non l'ho mai sperimentato, invece il fatto di alzare l'asse posteriore e quindi abbassare l'altezza da terra c'ero arrivato
non credi che il problema che abbiamo sperimentato entrambi, spinout in entrata o in frenata, sia in qualche modo correlato?
@ Rune: what do you think about top-shock vs DPS?

Regarding the different dampening solutions available, my personal favourite is side dampers and a top shock.
I changed to this for a couple of years ago. Reflex Racing had a side damper that were made to fit with the Kyosho oil shock.
The main positive i think is that you can use different dampening fluids for side dampening, and other for up/ down movement. Now I use the PN system on most of my cars because you can adjust tweak with spring preload and tune the spring rate of the rear with T-plates and springs. Oil filled shock on top, and side dampers with heavy grease in the side dampers. Kyosho 15000WT to 30000WT.
You can be just as fast with a DPS, but I feel that the side dampers are much more consistent, and require less maintenance. Also I feel they have an advantage on bumpy tracks.
As for spinning out problems. When the car spins out on throttle in or out of the corner, add preload to the front springs. This adds some understeer on throttle. For spin outs on corner entry, try some smaller diameter front tires (to lower roll center), or stiffen up the front end. You can also use a slightly harder T plate to make the car go flatter to the turn to reduce the roll of your car. This can help prevent spin outs on corner entry. (This must of course be adjusted to the grip levels at your track).
Lowering always gives more traction to the part of the car that are the lowest.
Spin outs on corner entry can also to some degree be reduced with the differential. Loosen the diff slightly so that it dont lock up when you release the throttle. This is especially important to think of if you use a light weight diff. (The new Atomic diff or PN/QteQ/Reflex combo)
The springs from most manufacturers are not very consistent, so check the length and if you can, the real spring rates. This way you can avoid tweak.
