there's some jackoff on ebay selling drilled/slotted rotors for cheap - mostly he's buying the parts from Summit on his mechanic discount reselling them to you through ebay at a discount.... to say they take forever to get to you would be an understatement.... and as my jackoff comment started this, I hold him in very dim regard.
For that price, get the part number and price check (or even better) price match through Summit. You'll save money, time, aggravation and be able to return the parts easily if they don't fit.
