I might need to replace my front and rear rotors soon. I only have 34K mi. Is that to soon to need rotors? What brand are the OEM's? Should I go aftermarket like Zimmermann or Sebro.....?

 

Are the rotors for a c2/c4 or c2s/c4s?
I recently replaced my rotors as well, 34k miles, because it was developing a sizable lip. I replaced the OEM with Balo Coated rotors from PelicanParts, very reasonably priced at $75 per rotor, Germany made, works brilliantly both on track and as a DD.

 

I have a C4S. I have not heard of Balo. I was looking on Pelican and only saw Zimm's and Sebro's. My rotors have a sizable lip as well. I was Goimg to have them checked with calipers to see if they are within spec or not. If not I'll replace now otherwise I will wait.
