New Front Rotors
Brake pads play a part in all braking solutions. Use the same brake pad on the same diameter rotor (larger will stop better due to a larger amount of torque being applied) choosing MMC, Stainless Steel, and Iron and see the results as we have. The MMC is much lighter and will not rust. It also has a lower melt temperature of just over 1,000 degrees F. These temperatures would never be reached on the street, however, on the track is another thing. Testing the new (at the time) Buell, the temperatures reached <1,500 degrees F. If you ever watched a race after the sun went down the Buell's front rotor glowed red. The riders of the Buell team did an exceptional job bring home the bikes at the end of the race. MMC was not suitable for the track and never used in an actual race on the Buell. Do not confuse Ceramic or Carbon rotors with MMC.
While I do not use Squeeze cast rotors, I purchase for my own bike Spun Cast rotors. MMC is lighter than either Stainless or Iron. The Iron rotor will stop in the shortest distance, rusts almost immediately, and is heavy. In no way am I saying do not buy MMC but the claim of using the same brake pad compound on all three material rotors giving the MMC rotor a 30% gain is something I would have to see and proven as it did not work on my application. The other positive factors is what leads me to use MMC on my bike. Would I still buy them, yes as I already have them on three bikes currently. This fork is new and designed to go on my FLT. I am currently working on fender brackets, the above is just to hold the fender on for measurements.
That is a negative. I haven't independently tested the Lyndall rotors against the factory rotors to verify the difference in stopping power. And I agree the 30% claim could be misinterpreted to be actual stopping distance which may not be the case, however, after many years drag racing, rotational mass reduction was the key to putting horsepower to the ground and "assisting" the braking system to bringing things to a halt as well (and a parachute). The Lyndalls are much lighter than stock and seem to slow things down better than the factory units did. In a panic stop all I need is that extra little advantage to keep me out of trouble , it's a game of inches and I hope it never gets that close but I like to know it's there when I need it. My next major mod to my bike after a set of your shocks is a set of Brocks carbon fiber wheels. Further reducing my rotational mass and freeing up horsepower and easing the load on my brakes at the same time. Too expensive to some and not worth it to others but to me it's the biggest difference you can make on a bike regardless of overall weight. It looks like you are already there with your setup. Pretty sweet btw. Hopefully this discussion will assist the OP in some way to find a rotor that won't warp and will fit his factory wheel. I feel the Lyndalls do that, albeit at a higher price of admission.

The OEM slab 11 1/2" SS rotors weigh in at 4.2#/ea. My MMC 320mm rotors 2.2#, my full SS 320mm floaters 3.4#, and my new CMC (Ceramic Matrix Composite) 1# 8.7 OZ.
C/F wheels will make your bike turn faster, as well as brake and accelerate faster. There is no difference at speed from a regular wheel. I spent a lot of money getting this bike a lot lighter such as fenders & aluminum swing arm when reduced weight & FXR's was not fashionable in 2006.
To the people who put large front wheels, heavy huge rear wheels, drop a rotor and think it is ok, you never really need good braking until the end anyhow. Read my articles on Rotating mass & Inertia.
