I'm getting ready to order front pads and rotors and I notice on the website lists only the right rotor in stock and the left one out of stock. I was wondering what the real diffrences are in the rotors. Now that I think of it, i dont remember ever checking to see which one went to which side when i installed them on other cars. Any input is helpful guys, thanks for your time.

The fins go in opposite directions and it will affect cooling. Will you REALLY notice? Will it really make a difference in all practical? I have no idea. But better safe than sorry, get the proper rotors.

^Correct, there are design differences inside of the casting of the rotors that you cannot see really well. So you will want to purchase a specific left and right rotor.

What exactly are you looking at purchasing? OEM or aftermarket?

Like others have said here - it's best to purchase correctly if your vehicle has side specific rotors (based on the curvature of the venting vanes). Although, there are makes and models that have curved vents that go in opposing directions; it is still best to get exactly what is meant for your vehicle.

Looking for OEM and I will be using OEM pads as well I guess. I'm just surprised I never knew this having been working on cars all my life. This is the first time ordering rotors online so I guess whenever I would get them at the store, they would automatically give me one for the left and one for the right and I was none the wiser any recommendations on aftermarket parts that wont break the bank?

Most cars don't have side-specific (L/R) rotors, it is usually on cars with higher performance brakes or when better cooling is needed. Some examples are the Supra Twin Turbo, IS350, GS350, LS460 with Sport Package, etc., that said, yes, you should make sure you get the LH and RH brakes and put them on the correct sides for proper braking/cooling.

Probably will not notice it, but that does not mean the rotor t would be the same. If one side is pumping the air OUT of the center of the rotor, to the edge to cool down the surface and the pad, the other one would be doing it in the opposite direction. I bet rotor would be cooling down a bit worse than the rotor on the other side, which will affect the life of the rotor and the pad on that side. I would not risk it. Having overcooked brakes on one side is not a good idea for controllability...
