I was wondering if anyone here has slotted their own rotors with a dremel tool. what are the draw backs of reslotting them a little once they start to wear down. I have tried searching, but was not able to find anything on someone doing this...I also was wondering if any one has added slots to their rotors. I have 6 slot rotors on the face side and back . I was thinking of putting 6 more slots on eachside. How hazardous is this to cracking the rotor. thanks

 

I don't think there would be any real benefit. No reason to risk it .

 

I think the manufactuer didnt put six more slots on there for a reason...Why mess with something thats working perfectly fine and you have little knowledge on...

If your worried about stoping faster, or brake fade you have few options...Big brake kit, and or upgraded pads. Fluid is also important if your gonna be tracking the car.

 

Doing it (essentially) by hand, wouldn't it be also hard to keep them in balance?

 

That is a really awful idea. Don't slot or cross drill your own rotors unless you want them to break.

 

Yeah, that is just a bad idea. The quality slotted rotors have the slots cast into them - rotors with slots cut into them will be prone to cracking and failure. A Dremel is way too inaccurate to do that kind of work - you'd need a CNC machine or something to accurately do it, and even then it's a bad idea.

If you have a milling machine and a dividing head then its easy to do. I have done loads and NEVER NEVER had a problem with cracking. I have turned the discs blue to test them and they have been fine.

 

just buy some crapy ebay ones, they will do the same as the dremel ones you try to make and will look better, but dont use the car
