I am almost positive that they had them on for around $1200 at some point, I would try to get them for that. You can also try pm to Kevin to see how much he paid.
$1380 for the 370mm rotors
$1244 for the rears
I finally got these mounted a few weeks ago. Took them almost 12 weeks to deliver these. They initially made the wrong hats for the fronts and it pushed back the delivery 3 weeks.
I couldn't get the refurbed red calipers as I originally wanted, so I just kept these yellow and bought the yellow calipers for the rear.
Weight saving on the rear wasn't as much as they specify. My 2016 MX rotors weigh 23.56#
The 2-piece fronts are marginally lighter than stock only by 3oz.
Overall the unsprung weight on the front went up because the loaded calipers are much heavier than stock.
Brakes feel exactly the same to me. I'm sure they wouldn't get heat soaked as quickly on a track, but I'll never have the chance because the nearest one is 2500 miles away.
