I’ve had my fuel ex for about 9 months now and the rotors warp fairly often. I have tried torquing the caliper + rotor bolts, and I have had to true my front and back rotor at least 4 times each. I’m tired of always having to listen as my rotors rub against the calipers despite constant efforts.
I do not believe the caliper is the issue, has anyone had similar issues with these rotors?

My Maguras are really touchy so I got one of those alignment shim things. I put it on the rotor where it’s rubbing with the caliper loose, grab the brake, tighten down, remove the tool and it doesn’t rub anymore. Used to spend 30 minutes at a time trying to get it just right.
Maybe use one of those metal shim tools?
Replace with floating rotors.
Replace rotors. You can true them but then once they get hot the metal shifts back.
The symptoms you describe can also happen if the axles aren’t tight enough. Riding and braking causes movement then they start to rub.
I have the same rotors, my rear one is warping often as well. It’s usually so subtle that straightening them is a real pain in the ass. Also make sure your pistons aren’t too close together, that will magnify minor warping
Those shitty SRAM rotors have a reputation for that. Replace, ideally something thicker.
I think sram makes 2mm rotors. Maybe try those before you replace your brakes?
That’s because you have Guides. Replace with XT’s and rt-86 rotors, solved
You just have straight steel rotors. Get rotors with an aluminum carrier. They’ll dissipate heat better.
I have the same rotors on my Foxy and they are absolutely shit. Always warping and fading. Can’t wait to change them out for the new Hope brakes when they finally release
2.3mm TRP rotors go brrrrrr and refuse to warp, even under sustained braking on stupidly steep trails as a 200lb rider. I’ll never go back to anything narrower.
My Shimano rotors were constantly warping and I wasn’t even doing anything remotely close to as steep as what I ride now.
Same issue swapped to the HS2 rotors and no issues since

Quite often rotors are bent because of a sticky piston on one side of the caliper .
Which is such a pain as it will keep happening randomly.
As someone else mentioned, floating rotors definitely help in this situation.
