Rotor Recommendations

Wrniknbl · 12-02-2013, 05:06 AM

I'm currently running Ferodo DS2500 with OEM performance Drilled and slotted front rotors which have been great on street and track.

However recently have noticed hair line cracks on the rotors and pads are starting to wear so am considering alternatives.

What have others moved to?

To be clear I'm after a set up that retains the stock caliper (but would consider a stainless steel piston upgrade) just don't know if there is a rotor/pad combo that I haven't thought of yet which still provides a reasonable DD (some noise and low dust) and is very reliable on track - can handle heat - 20 min sessions - without fading.

I'm also looking at recommendations. StopTech makes slotted/drilled rotors for our car. Not too expensive either. Anyone use them?

Just throw on a set of stock rotors.

Really depends on how much abuse you put your rotors through. Spoke at length with a track veteran who recommended I use cheapest blank rotors (no slots, no holes) such as Centric, Zimmerman, OEM etc, and treat them as disposable/wearable item, if they are going to see heavy track use. The brake pads are what matters the most. Best option is dedicated set of rotors + pads for track, and another set for street, if you are a DIY person. Not fun if you visit the track very often.

I still have my stock blanks so I guess they are going back on. Thanks for your feedback.

I agree with dcaron. Brake companies are great at convincing you their $200+ cryo treated, metallurgically aligned, yada yada yada rotors are better than $40 blanks from Autozone, and at a scientific level they probably are, but the actual impact on driving performance is debatable. The most I can say is they might last a little longer.

I do know there is a very good article out there from Stoptech themselves that says slotted/drilled rotors are basically for show. Outgassing is a thing of the past (pads aren't made from asbestos anymore), holes just lead to risk of cracking, and slots just wear your brake pads faster (with the minor benefit of keeping the pad surface a bit cleaner).

Personally I wouldn't buy the cheapest option available, but I'd go for a mid-low price range blanks from a reputable brand, giving a little piece of mind that your brakes were developed with stringent QA tolerances but don't come with complicated manufacturing processes that just drive up the price.
