I am looking to get some 2 piece rotors for the track seasson coming up and usually I get dba5000 2 piece for a very good price thru my buddys shop (550.00 for the front once). I found some APM 2 piece rotors and wanted to see what u guys think bout these and has anybody used them. BTW i got brake ducts, and RS14 Pagid in the front so that helps on the track a lot. Any opinions? Thank you in advance.
