Anyone have experience making their own set of slotted rotors from the stock ones? I've got access to a machine shop, but was wondering if there's anything I should be looking out for or any tiops on dimensions of slots/holes and quantity

 

...why in the heck do you want to chop up perfectly good rotors.

For looks?

Head to the track, and see how many of the "fast" guys, run slotted rotors.

 

I do. I'm fast. Track record for my class. I would advise against a home made set though.

Then fork me some of that dough for new brake pads, as thats all a slotted rotor is good for, chopping and cleaning the pad face.

 

I was under the impression that cross drilling adn slotting will help in dissipating heat under hard braking??

 

Trust me, I would be running plain rotors if I didnt have a sponsor from a local shop.

you are correct sir! i dont know what that guy was talking about saying it was for looks

 

obviously a rotor AND pad sponsorer



and no there is NO reason to cross drill or slot a rotor, none whatsoever.

The pf 2 piece's are dimpled... helps you tell the service limit of the rotor

 

cross drilling simply gives the rotor a spot to start cracking from. WHY oh WHY would you want to crack your own rotors?

Take a car out to the track, once even, then come back and tell me how brakes work man.

 

cross drilling doesn't do well at the track...cracks only good for the street..

slotted are better for track use..

BTW dont know how good you are with machine tools, but I would never do it..


For the amount of time & money you will be spending its much better if you just buy it..

 

ok...im telling you that cross drilled rotors dissipate heat faster than stock ones...
i never said they ran faster at the track or even that they dont crack...

if you want to try to correct my comment good luck because plain and simple...cross drilled rotors dissipate heat faster

 

No, actually a properly designed veined rotor will remove the heat faster.

Take a look at maybe the Performance Friction, or Statis Alcon setups, and tell me you can do it better

 

To the OP, don't waste your time. Best case scenario, you won't see any improvement. Most likely scenario, you ruined a good set of rotors.

lol...ok so take a rotor that is cross drilled and put it up agains a rotor that is properly designed... ummmm yeah you are correct....now if that same company made that same properly designed rotor cross drilled it would cool faster than if it werent...

 

dude, what are you missing? A drilled rotor is more prone to failure. Thats why they don't make them, nor do you actually see people running them.
