Just wanted to share my story about my Alcon rotors. I had a total of 5! My last session was yesterday at Daytona and these things can't hold up to the abuse the GTR puts them through. I ran at Daytona in December (1 day) and Nola (2) days just a few weeks ago. This weekend I ran at Daytona for 1 quick session yesterday and had problems with my CV boot and a tire rub. I was only able to get in 5 laps the first day and my day was done. We worked on it all night and was able to make it out on Friday for 5 sessions (30 minutes each). Checked them to see how they are holding up, well you tell me. I ran them with Endless ME-20s. I don't daily drive it, I might take it out on the weekends.

(Edit) I have edited this post after talking with Shariff at Forged Performance. He called me and I explained what was wrong with the rotors. He called Alcon and they listen to him about the rotors (400mm) and are taking action.

I didn't expect anything from Shariff or Alcon, however they are stepping up to the plate. I will post more when I get more information.

400mm is a light weight rotor for daily driving fmpov......,i even needed to have a HD version of the 380mm disc as our german drivingstyle isnt what the normal discs liked.....,the HD version is lasting whatever you throw at it....

People need to realise that a lightweight rotor and trackuse isnt suitable....,youll need lots of metal to take the heat.....

Just was sitting her thinking about all the work we had to do. You have spacers as these are floating rotors and we had to shave the ME-20's down to fit. With my J-Hooks I just put them on and off I went. Lasted over a year. I am testing out the RB Brakes as well for One Lap and will update as we go.

That certainly sucks especially since you likely dropped a few grand on them but did you ever think to contact the manufacturer first to give them a chance to make things right before blasting them publicly?

Heard about 2 400mm sets in Sweden that cracked, My tuner recommended the 380mm.

They are operated on a too high temperatur...,simple.

You can break everything if you try hard enough. Seems you did.

I have seen discs from all makes breaking....,so im not shocked at all.

No I did not. Do you think they will give me a full refund or a completely new set?

No you could take the replacements and sell them. Use the money to fund a different brake solution.

No I did not. Do you think they will give me a full refund or a completely new set? I highly doubt it. I don't want them to give me a new set as I would have to space them and cut my pads, and for what? 5 track days? I think i will pass on the Alcon rotors from here on.

I'm real doubtful he'd get free replacements on a wear item like that.

This is how is mine looked like after 1500 miles of street use no hard breaking. Alcon rotors with Endless 72
And when I emailed them they told me that they have not been bedded in. So i had to resurface them and get them bedded in. And guess what the hotspot where there again.

Hmm i have the alcon 400 as well, but dont track much or as hard. I will have to check them out once i get my GTR back from the installer.
Little disappointed as if i knew this earlier i would not have bought them.
Actually auto finesse was selling a set of used ones after a few track days which had me a little worried looking at their condition.

Pro- I didnt het the hotspots you have, but have a circumferential line running around my rotors, almost like there is a rock between the pad and rotors causing it to etch a perfect circle.

My educated guess the hot spot are caused by pads having so much friction the ABS is letting the rotor go and grab again. When I had Hawk HPS, there were none of that, very even pad on rotors because the pads couldn't really lock up the rotors at any high speeds. Now I changed to MX72s and have hot spots, but I can tell it improve my braking greatly.

I destroyed a set of 400mm in one session at road America. They warped in one lap! When I contacted Alcon,they told me it was my fault,and to pound sand! I took pictures at a machine shop with marks made with flat surface and a dial indicator.nobody gave a $hit..Big waste of money! mE 20 pads..in may ill see how the AP's hold up! 2012 GTR mid pipe,stock tires,last year.This year I'm running 285 MPSS square.

Why did you need brakes at Daytona? It's a big oval. You just go WOT for 30 minutes. :)
