Don't have a picture of it right now, but the rear rotors on my 13 R/T have cracks in them. Will get pics for reference when I get back home, but in the meantime, any thoughts on what caused this?

It's more prevalent on the left side...

Potential causes I can come up with are:
Too much power? I am over 500 whp
Too big of a wheel/ offset? They do have the correct bolt pattern but are 11.5" wide
Too many high speed runs?
Too many burnouts (or just a couple bad wheel hopping ones)?


Also any recommendation for what to replace them with to prevent this happening again would be appreciated.

Just taking a stab in the dark. Those ridges appear to be on the large side for rear brakes with 36K miles. As well the wear lines look a little deep. Is there some condition creating more heat than normal?

Looks to be too much heat. Don't have a frozen caliper do you? Speed, wheel offset or anything else you mentioned I don't see causing that.

My WAG is the rotors wore out, became too thin, and there was just not enough metal mass to deal with the heat generated by braking probably from high speed.

If you are doing brake stand burnouts on older rotors, this can be the cause. Excessive heat on thinner rotors.

Get some new rotors and a line lock and burn tires right.

The ridges on the rotors look like the front rotors on my ‘13 RT. I was getting vibration on light to medium braking. 35,000 miles. Was pretty hectic on the one track day I went to. Other than that I don’t drive hard... at least I don’t brake hard.

I Mic’d them at the local auto parts to see if they could be turned but they were worn down thinner than the minimum that is stamped on the stock rotors.

I ended up replacing all four with stop tech sport slotted rotors and street pads. Very happy with the performance and very little brake dust.

I once encountered a partially engaged emergency brake with no indicator warning light and that really started to overheated the brakes the 09. I discovered the problem before any serious issues came to light....

Yeah. I need a line lock, probably was a combination of the burnouts and high speed shenanigans I do.
