Yep those two part numbers look good for your non-pp 352mm front and 330 rearI am so sorry to reply to an old thread but I am a track noob and I need some help.
So, would these be ok to run on a 17 5.0 non-pp?
Based on the discussion above, the 121.xxxxx is a cost-effective way yet with relatively good performance? The premium line is basically the same performance with more rusting?
Just FYI, the selected 121 is the standard and 120 is the premium.
By my understanding of also reading all the comments over TMO, these are good cheap alternatives opposed to huge price jump for two-pieces.
I also purchased the high carbon centrics from rockauto just a week ago, gonna install them tomorrow!
