My question is if putting on new wheels will result in being able to see the rotor better,,and I decide to put new rotors on too,,,"drilled and slotted" or just "slotted" which would look a whole lot better and better braking,,,,which rotor would be a good choice? Not intending to change caliper, stay with stock,,,may consider new brake pads,,,,but with that said,,,which rotor would be a good replacement?

Thanks

Well the only way to properly see a rotor would be to go with a wheel that has excellent view through them. And to answer your question any rotor is technically better then the one you already have. I would say to steer clear of any drilled rotors, a lower quality rotor will tend to crack under any sort of excessive heat issue just around the drilled area of the rotor. So just stick with slotted rotors for the time being, and you should be just fine.

Do you by chance have a brembo brake setup? If you don't you will most likely run into an issue with any aftermarket rotor, being that they will vary in MM width causing a fitment issue.

As for the rotor question, what are you looking for performance wise out of your rotors?
What is the intended purpose of the car? (daily driver, weekend autox, strip, full on gt racer) A good choice is dependent on what you want to do with your car.

With that said, drilled and slotted rotors sacrifice friction surface area to improve initial bite (adding leading edges that grab the pad a little harder) and improve cooling (partly by having less mass to heat and partly by allowing more surface area to be in contact with the air, thus improving convective heat transfer).

So if you want optimal street use, leave it stock, because you simply don't need what drilled and slotted rotors offer. If you want some added initial bite, go with slotted over drilled and slotted for the cracking issue mentioned above. Cracking occurs from excessive heat and rapid cooling. So the metal gets super hot when the pad is over it, then cools too quickly once the pad passes (also can cause warping).

The thing with stopping power is that if you can activate your ABS you already have enough, what aftermarket performance systems attempt to do is maintain that stopping power for repeated hard use. Stock brakes will lose performance the more you use them, performance brakes attempt to minimize the loss of performance from heat. If you're looking to reduce stopping distance for a single emergency stop situation (the end of a run at the strip), you should start by getting stickier tires.


If all you want is a cool looking rotor, I think those wave slotted look really cool, but that's down to personal preference.
