I tried losi hydridrive but it's to fluid.
I also hard silicone dif grease and corraly syrup but afer one run, there is so much dirt that dampers have to be remade.
actually i'm not satisfied with this damper system ( my car is an SB12 Spachett ed).
Finally i put the dampers (close shock but without spring) from my pancar trinity SB10 and it works very well.
