I'm looking into purchasing these rotors, however I came across 2 different sets. One says t slotted uni directional and one says slotted. Can someone explain to me the difference between these two? Pictures looks the same but discription is different. There is also a 50 dollar price difference... Thanks for any info

These are the same T3 design rotors.$130 are for the rear thats why its cheaper.

**** stupid me lol thanks I thought I typed in same part number in both

Actually if you look at it closer it's 144 for front(dba4418s) and 130 for rears(dba4419s)

Right,19s are rear,18's front.different part numbers for different rotors.

Amazon is 198 for fronts
