Who have home made Drilled brake rotors

[Slow5.0]

First off all i'm from Bosnia/Europe now live in USA and my englich is bad so don't critize me

I just wandering who have home made drilled brake rotors

 

[stangman]

actually drilled rotors really aren't the best thing around anyway since it allows stress cracks real easy...ball milled rotors are much better.

I wouldn't do it...the holes have to be chamfered properly to avoid stress risers, the rotors probably need to be a bit thicker to make up for the missing material, etc...

correct, they are thicker & are usually coated in a hardened material

Well yesterday I finish drilling rear rotors (this ones are free so if I mess up ,I don't care) I didn't install them yet
Here is pics

I'm pretty sure this is not something you should do.


There is more to it than just drilling holes.

i would never do it. when brembo, baer, etc drill rotors they use a computer controlled drill with a special bit to do it. doing it at home with little pen marks is such a hack way of doing things. spend the money for drilled rotors from a manufacturer. or else just upgrade to the 03/04 rotors. they are better than you might think. i was watching 600+rwhp cobras at buttonwillow doing just fine with the stock brake system.

If you just drill holes in your rotors, you create hard spots and will your brakes will chatter. I know this, I have done many test on brake rotors and when you drill out rotors at home, you heat up the material around the hole and it hardens it, then these spots wear less than the rest of the rotor and you get pulsating in your brake pedal, and to top it all off, you can't turn them either. Good luck

Please don't use those.

Please don't tell me you believe in those drilled rotors because of outgassing. If you're going to do competitive racing, put some racing-oriented pads in there (for the race, don't be an idiot and use racing pads on the street)......I'd like to see you get race pads to outgas.

Please don't use those.

I 2nd this. DO NOT USE THEM. If you slice up your pad with them you are f'ed.

Carbon fiber brake pads (seriously) are excellent. I had some on my Cougar with cross-drilled rotors (KVR) and they were amazing. I put some cheapo pads on after them and it was an extreme difference. The rotor isn't everything.

I beleiuve the proper way to drill rotors is to actually cast the rotor with the drilled holes already in them.

Do not use those rotors, you have compromised their integrity

Agree...Even the cheap drilled rotors are junk!! My buddy had either the Powerstops or Pro stops or something like that...The front one flew apart, put a whole in his cobra r wheel, went up and cut the entire wiring harness on its way out the top of his fender...

Here's my reply to your post on Corral.net...

The only things cross-drilled rotors are good for (with the exception of Porsche cast rotors) are pimp factor and early rotor failure. If you do the drilling yourself, your rotor life will be even less than those done on a CNC machine. Don't waste your time and money as you will be potentially risking your life and those around you should you have a catostrophic rotor failure when you need your brakes the most.

Here's a great thread from corner-carvers.com that provides real tech behind cross-drilled and slotted rotors.

Sorry to rain on your parade. I just hate seeing people inadvertently putting themselves and others at risk by trying to save a few bucks.

Good luck,

Ok guys I have made about 10 threads on different forums and everybody sayin thats unsafe so I ain't gonna install them

Thank you guys anyway

Good.

And dear God........how does you car weigh 3900lbs?!?!?

94-98 GT Convertibles are heavyer than 99+ GT convertibles and I weight 300LBS so count
