Ok to generalise here a bit on damping and oil wts...
For me it seems that the standard pistons (.8mm holes) with the 100-200wt oils reccommended per the assy instructions is comparible to the 1mm pistons with 30-40w oil. I enlarged the holes to allow the option to run lighter damping. With 100wt oil there was little room for a softer adjustment to match the settings of comparible cars i.e. the Tamiya-evoIII, Yok-SD etc...
I have tried Sway bars of 1.2mm Fr & 1.0mm Rr, with the higher roll-center there is quite a reduction in chassis roll. I am experimenting with the sway bars as a fine tune for front-rear balance.
You obviously are far more familiar with the Alex products, I just want to bounce some of this around to gain a better perspective of things. There are far fewer CUDA owners here so you have the decided advantage (being in Japan) of seeing more ideas about setups. Thanx for any ideas you have.
