I cantacted them via phone to ensure i was placing an order for the correct products, but there was still an error in the order. The person on the phone should have been able to prevent this from happening. Now i have to return two of the items. Before ordering from this vendor, i would highly recommend double checking all part numbers with the mfgr's site to ensure that you are ordering the correct parts. Item descriptions on autoplicity are incomplete - no reference to whether i was purchasing front or rear rotors.
