Brake Service (Replace Rotors?)
I have 12K miles on my LC w/performance package. It seems my brakes are already getting close to replacement according to the dealer.
I will be upgrading to the Tom’s Performer Pads but the I wanted to know if I need to replace the rotors as well.
The dealer says they can be machined but coming from many years of owning various AMGs I remember that I had to replace rotors each time.
I searched the forum didn’t find much discussion on rotors.
Any thoughts or suggestions are welcomed.

Machining or turning modern rotors is never needed IMO, unless the rotors have embedded material that causes high spots and and you feel pulsating when applying the brakes.

Rotor thickness on an LC is 36mm front and 30mm rear. I have not been able to determine the minimum rotor thickness, but in my ISF it was 3mm from new thickness. So, the LC would see a minimum thickness of something like 33mm and 27mm front to rear. You can measure with a long reach caliper. 12K miles is pretty early to be replacing brake components.
You have a choice of two OEM pads the lower performing, lower dusting and less noisy pad or the higher performing pads that came on your LC.
When I replace I will be replacing with these PS pads:

If and When Rotors are required I'll shop for HiPo rotors in the aftermarket.
BTW, Lexus says rotors should last from 30K to 80K miles.

I'm at 24K miles with no issues thus far. If I'll need to replace my brakes (including rotors), I'm thinking of going with Lüften Brakes - one of our members had them and was satisfied. I'd probably go with 8-pot fronts and 6 or 4 - pot rears. They're also HIGHLY customizable - including the hats:

Rotors can and still warp under certain circumstances when they are very hot then taken directly into a carwash, power washed, hosed with cold water (some are more robust than others). I always wait for mine to cool to the touch before washing any of our vehicles. Some can also warp if the lug bolts are well over-torqued.

Thanks sickpuppy. This helps a lot. I’m going to do a pad swap only and verify the rotor thickness.
I went for the Tom’s performer pads. I don’t think I’ll need new ones and neither did the dealer. I think the suggestion of machining them was just from a misinformed SA.
I know they are not warped but they produce SO much dust.

I’m second owner and bought the car with 9K miles. I haven’t tracked the car but I have been lucky to enjoy some great spirited drives in the mountains.
AMG insists you must change the rotors with the pads and coming from a 700hp car it would eat rear brakes from the traction control.
That’s why I was asking if I need to change my rotors but that doesn’t seem to be the case.

anyway, i'm not worried about rotor warping.
