Ive always been disappointed with Centric rotors. Every single time I’ve used them. I shouldn’t have done the same thing and expected different results by getting new c-tek rotors but they were just too cheap to not try. Too big of a price difference between the c-tek rotors on closeout and other brand retail price.

 

Good points, pads don't always last the full life either. I ran my finger across the rotors to see of there were any obvious uneven spots but could not detect anything.

I believe but can't remember for sure that I had some centric blanks on my 400 and they did not last long either. By the way I officially gave the 400 to my brother yesterday. Anyway I have Centric rotor on the left and Raybesto on the right for now.

 

Honestly, I think the pads matter more than the rotors when we're just talking about plain rotors like these. The "warping" is caused by pad material being deposited to the rotors. Some rotors may have hot spots that contribute to that, but the pad material does too.

My mechanic told me that the complaining we hear about OEM Lexus brakes and feel and warping and them being really grabby is the pads not the rotors. On my rear brakes he just did, he "buffed" the rotors (didnt machine them) and just put the same rotors back on. They feel fine.
