careful with cross-drilled, I heard they crack easy. but back to one of my questions: can you turn slotted/dimpled rotors? seems like the slots/dimples would wreak havoc on a lathe bit.

 

They do...

I had one tech/manager hate me, for getting him to cut one of my crossdrilled rotors, it ate 3 bits.

Rear disc would be a much more effective upgrade than any drilling/grooving/hacking of a front rotor.

 

I agree that solid rotors are probably the safe and best choice for the type of driving I do, but heck, I figured for getting them at less than half price, i might as well try them. Or just invest that in new solid rotors/upgraded pads. Mostly I would want them for the wow factor.

 

You me the " " factor?

 

is that a "D'OH" as in Homer Simpson???? lol

 

Personally, I've had only bad luck with aftermarket custom rotors, whether they are cross drilled, slotted, dimpled or in the shape of a klondike bar!

They warp quickly, and are generally made from substandard blanks (especially the cheapos). I bought them 5 times in the past 7 years (they say the definition of insanity is doing the same thing over and over, expecting different results!!!) and have now sworn off them in favor of good old stock rotors. I think they are more of a fashion statement at this point than a performance improvement. I just replaced the fancy slotted/cross drilled ones on my 05 with bone stock ones, and braking is great again. The fancy ones lasted all of 4000 miles before they chattered and shook beyond belief. Ugh.

FYI, this was on an assortment of cars from an Audi A8, to an 01 Dak CC, to an 05 Dak QC.

 

As in stock do you mean OEMs from the dealer or like Factory Replacements from Napa, Autozone, or other? I have always had decent luck with Napa and or Autozone.

 

No, that is a facepalm.

 

Usually factory replacements. I've also had good luck with most of them. Rotors are really cheap to make, and they seem to come from every country under the sun. I'm sometimes not even sure if you could find the source of many of these aftermarket rotors. What's interesting is that prices vary wildly, for what is for the most part, a commodity part, especially on a volume car/truck application.

 

like I said in previous posts on the subject, I've had nothing but good luck using basic o'reilly's plain jane rotors and semi-metallic pads. Just was presented a chance at these for a good price. The intervention has worked, I'll stick to my solid rotors.
