There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

I just replaced the rotor on my RT with the EBC rotor from BajaRon It was an easy fix and a lot less than $500

Brake rotors
2,500 miles of riding should not have produced warped rotor discs IMHO ?
First thing I would is find a non-Spyder brake shop and see if they have a clamp on dial indicator and have that person check the rotors for "runout." What is "runout." A measure of the flatness of the rotors surfaces.
Once you have that data you can determine if the rotors are indeed truly warped.
Do your rotors where the brake pads ride show any signs of wearing unevenly or hot spotting (metal surface dis coloring from excessive heating up?). The braking surfaces should be polished, smooth (no grooves or gouges). While your looking check your brake pads for uneven wearing down, front to back and top to bottom.
How do rotors get warped? Not being a certified brake person I can only talk from mine an here say from others. Excessive over use or abuse of the brakes combined with rapid cooling such as running through a big water puddle after heating the rotor to glowing. I probably have a total of a 1/2 million motorcycle miles under my butt and have never warped a rotor or cooked a brake drum since 1955. When I worked with a known race mechanic I saw a lot of warped rotors and out of round brake drums in my very limited exposure to the race shop experimentation works or bad idea stuff.
after you determine the accuracy of the dealers comments and they are truly warped beyond machining tolerances if your mileage is within BRPs warranty perimeter I would call the Customer Serice Desk and present your findings and go from that point on.
Good Luck!!!

Front wheels need to be to be torqued
The front wheel lug nuts need to be torqued at 77 lbf -ft as per my 2009 gs operator guide @ page 109. Last june I recieved 2 EBC rotors from Bajaron and since I received them a few hours before leaving for Durango ,I went to my trusted auto mechanic for him to install them.He estimated torque to be 75 to 80 lbf-ft and I happened to check the owners manual and found it to be 77 lbf-ft. He first torqued them at 55 then 65 and finally 77. He said that floating rotors will warp if not torqued properly. I've since driven aprox. 30,000 km and are still vibration free.

Besides the torque issue mentioned above, driving long distances with you foot riding on the brake can also overheat the discs, causing them to warp. This should however cause all three to warp, not just the front. Just a thought, I have no idea of your personal driving habits.

If both are doing the same thing it could be related to your driving habits, there aren't a whole lot of complaints about this problem. If you are overly easy they can get a buildup it seems, my GS has felt that way occasionally, along with the sqealing. I will get up to about 75 MPH and get on the brakes hard all the way to a stop a couple of times, it seems to help for both problems and it's an easy thing to try. I also block sand my rotors with a 2x4 and some 120 grit before installing new pads, knocks off any surface debris and helps the pads bed in.
