i baught 2 "roto-tech" slotted/cross drilled rotors for 30 bucks. at the time i thought i checked and i had a left and a right. i just put them on and they both were lefts

so i put them on anyways... i got some 40 dollar lifetime warranty brake pads from autozone so i don't care if it tares them up, and the rotors themselves only cost like 24 bucks a piece. they seem to stop in a straight line.

so will bad things happen? if they eventually go bad oh well, they were cheap and the pads are lifetime replacement . the only thing i care about is if it'll stop good and if it'll stop straight.

they seem to grip a lot better than my previous pads / rotors so i'm happy so far.

 

Here's an article that may help - http://www.baer.com/Support/TechTips.aspx?TechTipID=2

Summary, it's the direction of the vanes inside the rotor that matter, not the slots on the surface.

you will probobly stop worse now with vents in the wrong directoin, slots, cross dills and crappy pads


everything in that setup is hurting you
just fyi
