sloted / cross-driled rotor question
 

while i was siting there watching one of my (stock) rotors get cut i was in a daze. then as i was thinking i should get some slotted/ cross drilled rotors as i was puttng the rotor and caliper back on. i go to set up the next rotor for cutting, and a thought comes to me.

how do you cut cross drilled rotors? or do you? if not.....why not?

anyone have any info on this for me? does it have to do w/ the type of pads you use for these rotors. please help my questioning. inquiring minds want to know.

anyone??????^^^^^^

just buy them pre-slotted and drilled - much easier

Be careful. I've read many reviews of bigger, better, badder, slotted, cross drilled...what have you...where the braking performance actually suffered on the FD. Choose wisely, I'd review the SCC Project RX-7 articles.

just get your normal brake rotor off, and go buy a 1/4 inch drill bit that can cut through metal. then, start randomly drilling holes!

you will notice less brake fade, shorter stopping distances, and longer brake pad life!

Hey guys, I think the post is asking whether slotted and driller rotors can be turned.

I've used a lathe a few times in machine shop. I don't see any way a slotted rotor can be turned. I doubt if a drilled rotor can be turned but it may be possible. I imagine it would not be very smooth if a drilled rotor is turned.

can they be turned? yes.
will you find a shop willing to do so? doubt it.

remember this is race tech filtering down to the masses. on race cars when a part gets worn or out of spec it simply gets tossed. that's how to approach these rotors for street cars IMO. they sure look cool too.

best way to turn crossdrilled /slotted rotors is to use a race spec brake pad...one that eats rotors...give it a few 100-0mph stops and tadaaa! rotors have been automatically turned!:D

There's no way to win in this situation. Everybody wants to get slotted or cross drilled rotors but once they start to wear what happens then?
So I think the only solution is to get a rotor that's capable of getting turned but delivers better stopping power than the stock rotor.

Can anyone say ceramic..... :D

Later,

ok. we started off w/ people thinking i wanted to drill holes in my rotors. WTF? where did you get that idea? but anyway. i think my theory was right that you can not cut them. i guess you just toss them like someone else mentioned. i asked one of my buddies from this forum who has cross-drilled and he didnt know either.
also somone stated that it would be hard to find someone willing to cut/turn the rotors....what if i have the machine? then will i be able to do so? if yes, please explain HOW? what settngs?

I AM NOT TRYING TO MAKE HOME-MADE ROTORS. i want to know how to "cut" them. "resurface" them.

I have never seen cross drilled or slotted rotors resurfaced.
I seriously doubt you will be able to do that seeing as how the surface isn't smooth.

I think you should start looking into ceramic brakes. At least you'll be able to surface those. If they ever wear out. Apparently the ceramic brakes should outlast the life o fthe car. Or so I'm told....

Later,

ok, do you have a link of where to get them?

Oh damn, they've just updated the site and now there's more info regarding those brakes.

Dude, you can't win.

I think it's just better to get better vented disc brakes. At the most I would go with slotted. But I would avoid the cross drilled rotors. You still might have a chance with slotted rotors with resurfacing.

The choice is yours....

Later,

I don't think ceramic brake rotors are readily available for a oem replacement. Endless has them but they are currently $600 a corner.
