This is all starting to not make sense now. When you put the lowering link on, you transfer weight to the back of the bike, as well as make the fork angle less steep. So where is the benefit coming from with the link? The weight transfer or the fork angle??? I'm thinking it is from fork angle. These collars do the opposite as far as weight transfer, they move weight forward.
Collars; Move weight forward
Benefit is more weight on the front wheel
Lowering Link; moves weight backwards, change the angle of the forks
Benefit is less steep fork angle makes the bike more stable, downside is taking weight off the front wheel may affect turning.
So it seems to me that the two would work well together. Use the link to reduce the fork angle, and use the collars to push some of the weight forward that link moved backwards.
I’m just thinking out loud here trying to rationalize what’s really happening.
