Default input needed on fork spring upgrade for dual disks

since i'm upgrading my bike to duals and i'll be breaking down my forks anyway, i figured i'd beef up the springs to deal with the dive.

i'm looking at:


leaning toward 11-1552, but thinking that i would be at war with the end caps to get the forks closed up.

any input and other spring suggestions are welcome. also... where is the stress being moved to when the dive is reduced? it's going somewhere, right?

How much do you weigh. I've got the standard progressive front springs in my superlow and they work pretty good. I had to use a 1/4 inch over the recommended spacer to get it where I liked it. I only weight 185 though.
And it was a b!tch to get the caps back on.

I went with the 11-1527 and used the standard 3 inch pvc. then after every thing settled I checked the sag and it was a little too much so I put in a 3, 1/4 spacer and that put it where I wanted. I could get the caps on with out too many cuss words but with the 3, 1/4 spacers I think I used some new ones. I had to get the wife to help me. You can vary the sag with the spacer length. I put 12.5 progressive shocks on the rear as well. The bike handles so much better. I also have a super brace on the forks. That made a difference as well. Mine is not as low as stock and I like it better.

so you no longer have low outside of those fantastic radials. cool, i'll get the 11-1527. i don't want to over do the springs because i'm concerned about that stress. if the front end is super stiff, that stress is getting moved somewhere, i just have no idea where.
