I have purchased rotors from this company in the past too, but not for the 4Runner yet. I found them to be very good quality and did not warp on a vehicle that had warped two previous sets of name brand rotors.
My 4Runner has 67k miles and has lots of pad left, but the front rotors have developed a shimmy after 1 or 2 applications at highway speed especially in warmer weather.
I am thinking about doing the brakes pretty soon, I like the oem pads and plan on ordering some, have not decided yet where to get the rotors. I do not like or want cross drilled or slotted rotors, just a good quality aftermarket product is what I am looking for. I may order from the above company or get a set of the high end Raybestos ones from somewhere else.
I usually do my own brakes on all my vehicles, but as I get older I have on occasion paid to have it done.
