Has anyone here drilled rotors themself? Any reason I shouldn't do it to a set of new blank rotors? Obviously, I'd do them evenly spaced so it shouldn't screw up the balance. I definately need better ventillation and drilled looks nice too.

I can only think of one thing on my car that I would never "DIY". You guessed it, my brakes. I would save the time an spend the money on a set of aftermarket rotors. At least if they fail you can blame someone else!!

I hope you're kidding??
regardless... I actually heard that if you aren't going to go with a plain rotor on our tegs, it should be slotted, not cross drilled. why?? I'm not sure. can't remember where I read it on the site (article, MD, or other). I'm bringing it up to see if anyone else has any info to back it up, cause I'm almost positive that's what I heard??

Rotors are cheap, in my opinion, you shouldn't have do this. I baught all four of my oem sized cross drilled and slotted rotors for 220 shipped, but I understand that these deals aren't always available.

Why do you hope I'm kidding? I figured people would give me these kinds of responses, but I'm really looking for an explaination as to why I shouldn't do it. Does anyone know how manufacurer drilled rotors are done?

I agree with the above.. waaaaaaaaaay to critical an area to do something like this on your own.....
manufacturers have super-expensive, suyper-specialized tooling to do this, it isn't some guy making $5/hour with a Makita
suggestion: forget it

You don't need slotted rotors for street use.

Blank rotors are all you need for street use. Anything else is just bling. Go to Pep Boys and pick yourself up some $15-20 rotors, works just as good Brembos.

my boy does home made drilled rotors
all he uses is a pattern and a drill-press and they come out perfect. a member on here has them on his teg,his name is B18c1tampa,he paid 45 per rotor to get it drilled,plus the rotor alone was 20

Weston,
I have actually cross-drilled my own rotors on 2 seperate cars. The first car that I cross-drilled the rotors on was my '86 Honda CRX Si. I had a problem with the CRX Si warping the front rotors (yes...I used a torque wrench to tighten the lug nuts). I initially had the rotors turned, but they eventually warped again. So, then I decided to purchase a new set of front rotors and cross-drilling them to see if it would prevent warping. After I cross-drilled the rotors I never had a problem with warping. Those particular rotors were cross-drilled for approx. 6 years.
When I purchased my '94 GS-R I had concerns that the rotors might eventually warp (similiar to the CRX Si). So after owning the car for almost 1 year, I decided to cross-drill the front and rear rotors. Since that time, I have done 7 HPDE (hi-performance driver education) classes (~21 hours of track time) and the rotors have performed flawlessly. My brother-in-law used to own a GS-R with identical suspension, brake pads and street tires, but the only difference was my brake rotors were cross-drilled and we ran similiar lap time (within .5 second of each other). After each lapping session we measured our rotor temperatures with a laser pyrometer and my brake rotors were usually 100-150 degrees less. So, I'm a firm believer in cross-drilled rotors. BTW, I have had my Integra rotors cross-drilled for 8 years now and I haven't had a single problem.
For my CRX Si cross-drilled brake rotors I used a "swept" pattern (see picture below). With this pattern there is a left and right side pattern.
For my GS-R, I used a more univeral swept pattern (see picture below). This allowed the same pattern to be used on either rotor. The pattern that I used was not a tightly spaces (ie. the holes were spaced out more).
I layed out the pattern on a large thick piece of paper, using a compose. After the pattern was made, I transfered it onto the rotor. I drilled the holes using a drill press and a 1/4" titanium drill bit. I also chamfered the holes using a countersinking bit.
Well, there is my $.02 on the matter. HTH.
