Low mile Monster clutch/flywheel has hotspots-what happened? I'll start by stating that I'm not saying anything negative about monster or their products. This clutch has been great for the 50 miles I've driven it.
I've been working on my build this weekend, got the engine and trans out today. Was taking the clutch(50 miles on it max)to find it has hot spots on both the pressure plate and flywheel. The flywheel is worse than the pressure plate.
The disc has a burnt/dark colored ring around the center, on both sides, again it's worse on the flywheel side.
So what could have caused this? This wasn't my first clutch install and I've never had a problem before, although I am human and could have done something wrong this time.
What should I do to fix this. New disc and resurface the flywheel and pressure plate? Input from Monster or other vendors would be great. Thanks in advance.

They need to cycle through the heat range to seat properly. You're most likely seeing the abrasion points on the surface which is part of the break in where the clutch mates to the flywheel and pressure plate.
I could be wrong but I'm sure SNL with will chime in

could grease from the pilot bearing be the culprit? wouldn't hot spots have more colors and heat expansion marks around the circumference? just asking I would like to know myself. strange both the flywheel and preasure plate. sorry I can't help.

Are all the friction surfaces actually flat ?
Seems really weird that the hot spots almost seen to align with each other on the cover and flywheel ?
I'd maybe have said there was driver error somewhere with lots of slippage.
But IMO there is something very wrong with that clutch. Most of the flywheel, cover and friction disc havent even been making contact, with all load on those high spots.

FWIW I pulled a clutch (twin disc) to fix a RMS leak after 500 miles. same thing, 1/2 of the PP & FW had hot spots. contacted clutch company and they said send it back (warranty). turned out the FW was .004 off from being flat.
They resurfaced FW and replaced discs & floater & PP. All good now.
I initially noticed a very slight vibe when I would just touch the clutch pedal but it immediately went away when I pushed in pedal. Turns out...the FW was not exactly flat
Monster has a good reputation on product and service, I would contact them

I don't have the instruments to measure it that precisely. Guess I need to find out if Monster has a warranty.

Just talked to Monster. Chances are, it was improper torquing. Not sure how I managed to do that but I guess we all make mistakes lol
He offered to check it for flatness at no charge and said that the clutch is good to go as long as it's flat.
Great customer service from Monster.

While it's all still relatively easy to get to, I would pull the flywheel off and check for cleanliness between the flywheel and crank mounting surface. A small piece of debris lodged in there could easily disturb the run-out of the flywheel.
Cleanliness is godliness when it comes to clutch/flywheel mating surfaces, as well as the trans to bell, bell to block etc...
