I do have a heavier rig than a stock Granite, so maybe I should have factored that in my answer. When I had 35W in my Kraton 4S with Typhon 6S shocks, it slapped the chassis from a 1ft drop. That seemed to me to be way too soft. I now have mine setup with 80W and it is much better IMO. It still slaps, but it takes a much higher drop to induce a chassis slap. Best guess is about a 4ft drop now.
Factor in a stock Granite will probably weigh a pound less than a Kraton and you might want something between 40W and 80W. But it all depends on how hard you bash. While I don't send quite as big as Eric, I do send on cement at the skate park, which I feel is harsher on the chassis than landing in dirt and grass.
that's exactly what I wanted to hear and
that makes sense ? i have rpm typhone 3s arms, hr adapters... and probably, it makes the 30wt oil too soft ... when i push the front shocks down they don't even go back up ? and when i drop the car from less than half a meter ... the car hits with chassis on the ground...i will definitely try with harder oil ?
