Brake Vibration during front braking:  2004 F4i w/ 13,000 miles & Galfer lines, pads, Motul brake fluid; Traxxion fork springs (.925)

I replaced the stock pads with Galfer pads & added Galfer stainless lines and replaced the fluid with Motul 5.1 - everything was bled with speedbleeders.  After the install, I got significant vibration in the front end during a track day - not enough to turn the bike, but enough to be a bit un-nerving during those hard braking moments.  I also swapped the stock fork springs with Traxxion springs (.925), the vibration increases with additional fork preload ( I assume the extra preload simply allows the fork vibration to be translated through the forks better due to the added stiffness under braking).  I adjusted the front forks per the Sport Rider compression/rebound suggestions as a starting point ( I don't think that I have a suspension setting way out of whack to cause this...?)

I've triple checked the fork heights in the triple clamps, and even double checked the oil level after recently replacing the fork seals.  Everything is assembled correctly and all bolts tightened per the order in the Honda manual with the correct torque values.  The forks don't seem to be warped using visual inspection when everything was apart during the fork seal replacement.

I tried measuring the radial runout of the rotors using a dial gage, but it's extremely difficult to measure given the fact that I can only use the outermost or innermost edge of the rotor for measurement.  Also, with the bike on the front stand, I can easily throw off the readings of the dial gage by simply pressing on the tire incorrectly while trying to slowly move the wheel and watch the dial gage.

The following pictures show the rotors.  I have noticed that since adding the Galfer pads, a pattern has emerged on the rotors themselves.  You can see slight light spots in the areas following the drilled holes.  I'm not sure if these are indicative of the rotors being warped since I've never seen a warped bike rotor.

I checked the pads in one caliper, the wear seems to to be even on either side and there isn't any excessive glazing.  The caliper piston area seems pretty clean and I don't think that there's excessive brake drag when spinning the wheel - but perhaps it is time to replace the caliper piston seals after 13,000 miles?  Could the pistons be sticking and contributing to this issue?

My guess is that the stock rotors were warped by the Galfer pads that I installed, but I would like to be sure before I drop $500+ on wave rotors as replacements.  Any suggestions or help with diagnosing this problem?
