I went with the Superbrace. I've had it on a couple different bikes now, and they all make a nice difference. The True Track however is a better upgrade. I use both.

 

"The cure for your weaving is to fit a True-Track handling kit! I have one on my FXDXT (and another on my dresser) and it transforms it. Bike rides better in a straight line as well as when cornering."

I've got the Sputhe mounts and aluminum swingarm, as well as Bridgestone radials; at speeds over 100kph in a sweeper, if I encounter a road heave or good bump, I can feel the chassis flex...the bike/rider are about 800lbs total; so I don't think it'll ever be as steady as an R1200RT; but mine will be more fun to ride with the 117ft lbs of torque...

I have a spare black superbrace, but it's for a nightster (39mm) with fork boots...

 

I've only felt what I think was 'rear-steer' once; but several times the front has felt just a bit wobbly. It is always at highway speed, cornering, with road surface problems. So for my birthday I requested a Superbrace. I installed it and promptly left town in my car, so I haven't had time to test it out.

I have heard that the True-Track is a very good fix as well, so that is my next purchase. As I see cash-flow, hopefully by the 15th! BTW, they are having a sale on the one for Dynas.

I have a superbrace. It works.

 

I have SE Brace and can tell the difference with not having it on. Highspeed and twisties the bike performs better.

 

Check out Custom Cycle Engineering. Not inexpensive (around $200 I think) but really well made.

 

I've got both too. Had the True Track for a few months first. I'm not sure the SuperBrace makes a huge difference, but I do think it's prevented a bit of a slippery feeling I had before on several frequent road spots.
