Aftermarket Brake Setup for IS250 AWD
So, i m do for some new brake pads and rotators
but i would love to do a BBK
but if anything for now i would jus do some aftermarket pads and rotators
so i jus wanted help upon what i should go with and all
thanks my ppls

You want better tires. The tires are what actually stops the car.
Whenever does come time to replace rotors you also won't want drilled or slotted ones, as they eat through brake pads 25% faster than blank ones do, while offering no advantages on a street car. You'd want OEM replacement blanks. (centric generally makes good ones).
(if it were a track car then I'd suggest slotted rotors... there's really never a good reason to put drilled rotors on a car other than a show car)
If you'd like to understand why upgrading your brakes won't actually stop the car any shorter, you'll want to read this:

Mainly slotting is more for keeping the surface of the pad clean ...street driving generally won't cause the problems this solution fixes unless you're doing something wrong though.
Removing mass from a rotor (slotting or even moreso drilling) actually reduces the capacity of the rotor to absorb heat. Rotors are heat sinks after all...a smaller sink holds less.
Here's stoptech on the topic:
(the "bite" is more a feel thing, as always your rotor won't reduce your stopping distance).
The "pad cleaning" characteristic is also why they eat through pads about 25% faster than blank rotors will.
This is a worthwhile trade on a track-driven car, not on a street driven one.
Drilled rotors will also clean your pads (and eat them faster) but are more prone to cracking than slotted and don't really do anything else for you that slotted ones don't, hence drilled is the least desirable choice for all conditions but show cars (since they look good).

Slotting helps wipe away debris from between the pad and rotor as well as increasing the "bite" characteristics of the pad.

I agree with you in some part concerning drilled rotors - they are prone to cracking (most likely due inferior materials and how they are made). But why do manufacturers like Mercedes Benz, Porsche, Ferrari as well as others spec drilled rotors on nearly all of their vehicles? I'm sure there is a performance benefit to having the rotors drilled. If there wasn't a quantifiable performance benefit, these manufactures would be spec'ing something else. What about Brembo?? Their claim to fame is their brake systems. Are their drilled rotors just for show?

Doubly so since all the fancy cars at car shows have em!
If there was you'd think F1 or NASCAR would use them, but they don't.
yes, they're for show.
Ask them, they'll tell you for severe applications they recommend slotted rotors, not drilled.
Ditto stoptech.
The rest of that stoptech quote from earlier in fact is:
"StopTech provides rotors slotted, drilled or plain. For most performance applications slotted is the preferred choice. Slotting helps wipe away debris from between the pad and rotor as well as increasing the "bite" characteristics of the pad. A drilled rotor provides the same type of benefit, but is more susceptible to cracking under severe usage. Many customers prefer the look of a drilled rotor and for street and occasional light duty track use they will work fine. For more severe applications, we recommend slotted rotors."

Slotted are fine for track use, but they'll wear out pads 25% faster and gain you nothing on the street in exchange for that faster wear. Drilled just suck at everything except looking good.

hahah yea i hate drilled so thats out of question
but i think i mma go with slotted because i was happy with them on my IS300
but yea gotta find some legit ones
