Cross Drilled / Slotted Rotors

What type of replacement cross drilled and / or slotted rotors should I put on my 04 6mt with brembo's ?

Not sure if I should put cross drilled and slotted or just slotted or just cross drilled ?

Any advice ??

Thanks

Either is fine, just make sure you go with a brand name to prevent the crackings if going with drilled or the combo ons drille/slotted.

I'd go with just Drilled rotors. I just figure you'd lose the slot first time rotors get cut, but I don't know that for certain.

Slotted rotors are really all the average "spirited" driver like us here will need. The downside to them is shorter brake pad life since the get shaved faster.

Cross-drilled rotors are more for real racing applications where you have to worry about the weight of the rotor among other things. And with road applications you have to worry about the drilled holes actually cracking with some of those cheaper products.

As far as loosing slots with cutting, there should be no need to have the rotors cut/turned if they are of quality! I've had my racing brake rotors for nearly 70+K now and they still brake as well as the day I got them. No shimmy, no vibration, nada!

STOPTECH/Powerslot make great quality rotors. I'd highly recommend their product. It features a power alloy compound, black coated hubs and vanes, and in some instances a curved vane construction.

Slotted package:

http://store.excelerateperformance.c.../i-304786.aspx

Drilled/slotted package:

http://store.excelerateperformance.c.../i-338784.aspx

We also have individual rotors for sale on the website:

http://store.excelerateperformance.com/

Just choose your vehicle and look under Brakes, then STOPTECH for drilled and slotted or Powerslot for the slotted rotors. STOPTECH = Powerslot

I've read/been told the opposite. I was always told to stay away from drilled rotors if you're going to track the car.

OP - If you're not tracking the car, go with whatever you like. If you plan on tracking, do some more research or just stay away from the drilled rotors just to be safe.

cross-drilled are better for "real racing" where every 10th of a second matters. Reducing weight on the rotor makes a large impact on handling and acceleration and braking! The downside is that they heat up a bit faster but in racing applications, that really shouldn't be an issue with the high speeds and amount of air-flowing through them.

Slotted on the other hand make sure the brake pad always is clean and has the MAX surface area to brake on.

IMO and good company who sells regular blanks with a better internal structure than stock will fair better than the OEM ones. The OEM ones warp due to heat, a better internal structure such as Racing Brake's will easily stop the issue. Only problem is racing brake has that improved structure on it's slotted and/or drilled rotors!

I've actually paid money to read the research on drilled vs slotted vs blank in addition to helping with a well known race team. I posted a brief summary of the results on here a long time ago.

Yes, there are cooling advantages to drilling under some conditions. No, pad life is not affected from drilling or slotting at normal to moderate brake temps. Yes, drilling gives a more conisistent pedal feel from cold to race temps.

Okay, so the requisite question at this point is -

^ I agree...unless its pure racing app(but still)...Brembo is suppose to have some really good blank rotors.
