Not even close. Heavier shock oil was nec for me. I run on higher grip bumpy indoor clay with large jumps. Talk about setups being difficult to find. Lol. 4x1.3 s are what I currently use with good handling everywhere except I still slap real good off the larger jumps, so hard I get a hop every now and then. With a tapered piston the fluid flow goes through a shallower port which affects feel. From what I have tested, I need to run 42.5 up front and 37.5 in the rear. This seems heavy but works good. Losi 55's required 32.5 up front and 30 out back on the same track layout. I just got some 3x1.4's tapered to test with next. Then I am gonna try some tricks with bladders on the 4x1.3's to control bottoming
