Green, pink and yellow are the next 3 rates down from the current big bore softest spring, which is orange.

Because of having a now softer rear spring option (I use the green most often but sometimes pink if very bumpy) I run my car with no additional weight, but even then my car weighs in at 1720g.

If the orange BB spring is the softest you have, it is worthwhile using added weight because they are a little hard without- I did use around 120g under my lipos when I ran the orange rear spring, car was back up at NiMh weight.

With smaller shocks, again it depends on which springs are in use. If using the kit black springs at both ends, definitely run with weight added- if you can come down softer to maybe the green or pink BX springs on the rear, you can then take the weight out- but as well as your spring choice affecting whether to use added weight or not, the nature of the track surface or layout can do also.

If on a very high bite track that demands a lot of quick direction change (lots of chicanes, tight and twisty corners) it is worthwhile trying to run the car as light as possible, making it more responsive. A lower grip track, or one that has many high speed sweepers can call for more weight to help keep the car planted at speed.

If your car feels too "lazy" and too "safe" it is time to lose the weight, if it feels too twitchy and unstable, add weight.

Not a right or wrong answer to the weight debate, sometimes more can work for you, other times not.

Thanks for yours advices, very usefull
