I did the same for the bottom of the fork tubes too and they still bottom out super easy, just braking hard not even getting the back wheel off the ground.
A friend was telling me I need thicker oil?
Possibly, or maybe you just need a little more. To be honest you really shouldn't have your preload tightened all the way down like you do.
