is it possible to cross drill your own rotors? will this pose a problem with rust or warping or anything. i just bought a set of brembo blanks because my stocks warped and i havent installed them yet. the cross drilled rotors are twice as expensive just for some wholes. any feed back appreciated.

 

I wouldn't recomend doing it yourself. Just don''t do it. If anything you could do dimple which is the same as crossdrilled ( in looks) except is only a dimple and not a hole, It has a similar effect of slotted. I think is easier and in case you mess up the outcome won't be so bad.

 

I wouldn't recommend drilling the rotors yourself. It would make the rotor weaker structurally. Most cross drilled/dimpled/slotted rotors are also zinc coated to prevent rust. If anything, do what Bitium advice and dimpled/slotted them.

 

how would you go about dimpling/slotting them? just drill part way. as i said its no big deal as far as performance goes. from what ive read, for most driving slotted rotors make minimal difference. if it is easy to do without any adverse effects, it seems worth it to me. thanks for the quick replies

 

Why don't you try it and let us know if you are pretty confident. I'm sure many people want to know, too. By no mean I am recommending you to do it tough.

 

I wonder if drilled rotors have some kind of treatment to make them stronger prior to drilling, b/c drilling does weaken them. If that is the case, drilling a regular rotor may make it weaker/more prone to cracking than a real drilled rotor. Ask they people you got the rotor from if they know.

 

That's pretty ghetto IMHO. Incedentally drilled/slotetd rotors are only better when used in extreme situations. Normal street use you will not like them, although they do look nice.

Someone asked about strengthening? Cryo-freezing hardens them.

 

I dont get your post.... does it mean that you like a ghetto look? As for the rest of your post, you are correct about cross drilled rotors only having any effect in extreme driving. Dont forget also that you cannot 'turn' x-drilled rotors. If you get warping, you gotta toss 'em.

 

X-Drilled rotors look a lot nicer behind nice rims than stock rotors.

X-Drilled rotors aren't ghetto.

Ask the manufacturer before you buy. Mine can be turned.

 

X-Drilling should be left to a CNC machine. You would never get the spacing as precise as a program could. You are asking for trouble if you try to do it yourself. Imagine a precisely weighed rotor and you randomly or systematically put holes. You effect the weight in different areas. A CNC machine is precise enough that after the X-Drilling is done you will have a balanced X-Drilled rotor where your attempt would throw off the weight balance.
