''I would say you have this reversed. Thicker lube will tend to keep weight transfered forward as compared to thinner. More steering. You can decide whether you think thicker lube results in a tick less turn in. I will hazard that most feel thicker lube results in more overall steering, and conversely, thinner more rear traction.''
Ahhhhh, the confusion...I must say, asking setup questions in a foreign language can get lost in translation.
So, when I use a thicker tube lube, it's basically like moving a rear touring car shock up one hole on a shock tower. Which will shift the weight transfer to the front. Moving the shock down a hole is like going to thinner tube lube.
