i just got some brake pads on monday. my mechanic told me that i need new rotors. i felt the rotor and a has small lip on it. my questions is should i buy the standard rotor(i know about warping from past topics)or get the drill/slotted ones

I think the d/s are not that much more. But might have to be ordered online, but I could be wrong.
Brakes

so if i get the d/s what pads should i buy? or can i keep the same ones i have now?

If you buy new ones, get ceramic. Some get the Hawk Ceramic pads, I think they run little more expensive, but I have heard, especially on here, that they are great!

OEM rotors are fine replacements. But I highly recommend spending the little extra for Hawks high perf ceramic pads. I have those and have no squeak and the brake dust is much more manageable. My fronts get as dirty as my rears use to and my rears stay a heck of alot cleaner now.

I just bought D/S rotors from eBay seller Gripforce. $147 shipped for all four. Pads will probably be $100 or so for the top quality ceramic pads, so if you care about the looks and lasting quality, go D/S instead of OEM replacements.

I bought Powerslot Slotted rotors and Hawk Ferro-Carbon pads. Sure, it's about the same amount of dust, but still much greater stopping performance. I noticed the it was much more cost effective to buy performance than stay with OEM
