The part numbers listed on the DHM site are the regular rotor part numbers. They end in SR, SL.. the cryo version part numbers end in CSR, CSL... is this a typo or are they not really the cryo versions???
Yep. I was wrong. I thought the Cryo were listed on the site as well. HOWEVER, we can get them for you.
The cryo treated rotors are supposed to last longer than the normal ones which would be really beneficial if you Road Course and daily the car. Or just want rotors to last forever lol.
Overall, either are better than the stock rotors. I chewed mine up in 20k. 15k on my non-cryo StopTechs and they still look new-ish.
