FXR brake upgrade - Why won’t this work?
I’ve already got a wilwood 4 piston caliper which is indeed an upgrade over the stock single piston, but I’m still looking for more. It’s still pretty sad compared to my other bikes.
Guy on the Dyna forum put this kit on his single disc Wide Glide and he said it made a substantial improvement. My experience is he’s trustworthy.
So, seems my options to improve my front brake are (in order of cost):
1) Lyndall pads in my existing caliper..
2) Lyndall pads and a new EBC floating rotor (will that even make any difference over the stock rotor?)
3) Single post 2000 left slider which will allow use of Arlen Ness big brake kit with Brembo/HD touring caliper.
Now to the expensive stuff...
A) Find a pre-2000 right dual disc slider, chrome it if necessary, second Wilwood GP310 caliper, stock or otherwise free floating rotor, appropriate new master cylinder and hose kit.
B) Find a pair of post 2000 dual disc sliders (chrome if necessary) and get two Arlen Ness big brake kits/touring brembo calipers, master cup and hose kit.
I’m going to try the Lyndall pads as-is, since I have them laying around. See what that does. I wish I had the skills to make an adapter to use the big rotor with the pre 2000 caliper bolt pattern, but I think that’ll be though for my limited skills.

You've already picked the low-hanging fruit from the tree (from stock to WW).
If that's leaving you wanting more, you'll never stop wanting more until you go as far as there is to go. The new pads may or may not make noticeable difference, but even if they do, you'll stop noticing it after a couple of days.
Given all that, IMHO the thing to do from here is go in a straight line to a dual setup. "No half measures" and all that. You know that's where this is going to end up anyway.

Ugh. $500 for a beat up right slider and another $200to chrome it.

If you used a 2000-later 39mm slider on the Right Side you could use the Wilwood 2000-later Cal and it would look very similar, but not exact
99-Earlier on LEFT .... 2000-later on RIGHT (you would probably have to shim the Right Cal inward slightly because 99-earlier wheels have even narrower hubs)

Before you go crazy and pay crazy high prices ... let me know, I have a few sets of those Early Dual Cal Sliders, but i wanted you to find a good deal and I am in no hurry to sell them if ever.
Back to using a solo Ness Big Brake kit (and this (or portion thereof) may have been covered earlier)...
There's NO Ness Big Brake for the 99-earlier sliders/calipers...
- So you could use a 2000-later 39mm LEFT slider and then use the Big Brake
- You wouldn't be able to use that NEW 99-earlier Wilwood caliper you have...you have to use a 2000-later Caliper
- You would still need to use some spacers (no big deal) to move the "Later" caliper inward for with that 99-earlier wheel

I bought EBC rotors and pads in preference to Lyndall. EBC is a large company with a world-wide distribution network, Lyndall seems a one-man operation who suffer occasional supply problems and had no stock when I last contacted them.
