Drilled & Slotted Rotors

CrossfireLTD · #1 (**permalink**)

I am currently planning to change the brake rotors on my Roadster. I will replace them with "Drilled & Slotted Rotors". Any recommendations or thoughts would be greatly appreciated.

BREMBO what else is there...

i don't think you'll ever generate enough heat on the road to actually feel the benefit of cross-drilled and slotted rotors, and our rim spokes are a little too thick to let them show through for bragging rights. if i can be nosey, why are you getting them?

I put Brembo slotted cross drilled rotors in mine and other than the looks it seemed to improve the braking mechanism plus the nice "swooosh" that you'll hear everytime you apply the brakes!

Just for looks, hopefully they will not compromise the braking ability of the car, I am in the process of getting new rims also. I have seen a few sets on Ebay and I know Brembo's are gonna cost. Just wondering if any other members have changed their rotors and what they went with, and their comments. I plan on keeping my Roadster a very long time, just want to dress her up a bit.

I agree, I do feel the difference and I could feel the difference in my brakelines also! Plus they look great. Don't forget to order them plated.

that's surprising. just might be worth looking into now --

i would definitely recommend Brembo or another big name you trust. once you drill a rotor its much more prone to cracking.

i would recommend the brembo's as well i got mine nickel plated from www.brakeworld.com they look awesome!

Dittos, mine are nickel plated grey!

They look awesome and stop different don't they! Nice sound too.

Mine seemed to change color like a rusty orange tinged, does that mean it's not plated? I bought it from TireRack.com.

Dan Root · #12 (**permalink**)

Yes, they all charge extra for plating the hub and vent holes, when you first got them they would also have plating on the rotor also, it wears off after a few brakes.

Where did you get your Brembo slotted rotors? Let me know.

Does Brembo carry them for the SRT?

Brakeworld.com carries Brembo.

Cross-drilled or slotted rotors are not ment to dissipate heat. Vented rotors are. Cross-drilled or slotted rotors allow the expanding gases that build between the pad and the rotor (when the brakes are applied) to escape. This makes the brakes work more efficiently. Plus they look really cool!

actually I believe the cross drilled rotors are not designed to remove gasses even though they do have that effect, but the real reason for drilling out the rotor is to remove excess rotational weight from the car's driveline. this is only necessary for full balls to the wall race cars who are trying to shave off every ounce of weight.

I doubt drilling perhaps 100+ 1/4" holes in the rotors would amount to any significant reduction in rotating mass. Also who in their right mind would choose to lighten (hence weaken) their primary safety system??? It is known that there is the possibility of cracking rotors at the drill points due to extreme driving conditions.

Are you kidding me ...anytime you can lighten up the rotational mass is a good thing...

At least that's what I learned in drag boats...the 10,000 rpm 2 stroke motors would always like the lighter parts...everything would last longer.

And yes nothing is safer if you’re pushing it!

First off the post was a discussion about Drilled & Slotted Rotors, not internal engine parts.

Second off you missed my point. Re-read my post. What I am saying is if you are concerned with weight and you want to drill your rotors [to shave some weight off your rotating mass] do me a favor, collect all your little drill shavings and weight it for me and let me know how much your diet worked out for you.

If you truly want to lighten your rotating mass you should buy a carbon fiber or aluminum drive shaft, ceramic brakes, carbon fiber wheels etc.

My point? That Drilled & Slotted Rotors aren't for weight savings, instead they help relieve the expanding gasses that build in turn forcing the pads away from the rotors. To back up my point I attached a screen shot from Baer brakes website explaining the purpose of the Drilled & Slotted Rotors.

Oh and what the heck does this quote mean.
