Stoptech BBK Rotor Replacement ?

jliffcones · 01-19-2021, 03:39 PM

Hello Everyone,

I recently purchased a BMW 335D which has a beautiful set of Stoptech 6 Piston Trophy brakes on it. Mfg#: 83.154.6700.R1.

However they seem to be really worn and appear to have hairline cracks all over them. Do I need to replace them? The entire car has only 27k miles on it.

See pictures below:

I have quotes from ECS to replace them.

2nd question, do I need to replace the pads at the same time?

Thanks for your help!

Do they look like they need replacing? The car only has 27k miles on it, and I am unsure when the BBK was installed.

Yes!!! Those cracks are definitely NO BUENO. Replace them pronto from what I'm seeing.

I'm no expert but that looks like a ton of stress cracks to me and I'd replace them immediately.
