Default what kind of rotors

i am looking to upgrade my rotors because i am tired of the rusty look.
i was wondering what type of rotors can i purchase.
i was looking at the brembo slotted rotors.
but i am not sure exactly what type.
i know that drilled rotors are useless so that isnt really an option.

you've "heard" that drilled rotors are useless.

anyone with little enough information on rotors that they'll go to HT and just ask like that should first assume they know less than that about what they're asking about.

if you're tired of a "look" get a different "look"

if you're tired of rust, get some brembo blanks or drilled or slotted, or drilled/slotted.

whatever makes your magic stone glisten.

Just pick up a set of AutoZone/Duralast or Brembo blanks. If you don't want the hats to rust, paint them with brake paint.

the purpose of drill rotors is to disperse heat better...better ventilation
slot rotors will have better braking. because of friction. (physics)

I have had Brembo Drilled rotors on my EF for years now and autocross the car and hae not had any problems with them. Thats my experience though. I would definitely stick with a good manufacturer though like Brembo or equivalent.

Only downside to drilled rotors on daily driving is with basic pads they wear out faster. I believe if you get upgraded pads with stronger material they last alot better (kavler i think).

As a matter of fact, a good portion of that is indeed for aesthetics. High-end auto manufacturers are not immune to the customer's demand for a "sporty" appearance. Also keep in mind that some of these high-end rotors are actually cast with the holes, not drilled. In most situations where brakes are used <u>hard</u> in a track setting, drivers tend to find that the drilled rotors are more prone to developing cracks, and do not provide a discernible benefit. In fact, the holes actually reduce the overall mass of the rotor, thus also reducing its ability to absorb and dissipate heat. A well-designed internal vane structure is far more important than holes, but obviously doesn't offer the "bling" that many people are after.

Can you elaborate on this?
