Best Rotors
 
I will be replacing the rotors and pads (Hawk Ceramics) on my daily driver which will see occasional track use this year for the first time. I own a base 997.2. Girodisc are the best, but that is outside my budget. I keep hearing to get slotted rotors rather than drilled ones. Is that true? I also hear do not go cheap as you get what you pay for. These are the brands I have heard are good: ATE, Zimmerman, Sebro, Stop Tech, DBA, Centric, Bosche and of course stock ones. Did I miss any? Any I should stay away from? Thanks in advance.

what size are your current rotors? On the 997.2 S its quite easy to upgrade to the 350mm 997 turbo rotors. You just need a small spacer for the calipers. Its said to show marked difference in braking and faster cooling.

Not sure on the exact rotor size. My car is a base 997.2 and I have read, although not verified, that the rotors are smaller. I know the calipers are different from the S model. At this point I am not interested in upgrading the brakes besides pads and rotors. I will already be running RBF 600 fluid.

When you are ready to buy check out fcpeuro. They guarantee the rotors and pads for life!!

I have looked at them and asked if they have the exact part numbers I need. I have not heard back from them yet. Just need to figure out rotor type and brand first.

I like dba slotted - 2 piece in front and 1 piece in the rear. Run these on my wife's car with the Hawk Ceramic pads. I have the Girodiscs from a 993TT on my 928. Both are good.

Drilled rotors crack between the holes when they get hot, so yes, slotted are better. Still provide an out-gassing path, keep the pad surface fresher, and don't have the cracking issue.

For dba rotors contact Ken at KNS Brakes (www.knsbrakes.com).

Are Zimmerman rotors equivalent to Porsche OEM rotors?

Yes Zimmerman rotors are the same as Porsche rotors. I put Zimmerman rotors on my base 997.2 and they had the same part numbers stamped on the hat.

I believe brembo is one of the oem suppliers and offers the rotors for the 997. Ive seen them on ebay and tire rack..

Brembo is the OEM for the calipers and Textar is the OEM for the pads.

FCP Euro describes Zimmerman quality as "Genuine." I believe that's because Zimmerman is an OE supplier to Porsche. I've bought that brand before for use on our 2007 MB C230. Quality is excellent.

Here is your "progression" list from street use towards track. Zimmerman/Sebro/Ate for drilled (street); Sebro for slotted (track); Larger 350mm slotted from Turbo w/brackets for track; DBA/Girodiscs 2ps slotted for serious track; StopTech kits for...

Good to know. Thanks.

For the money I run Sebro Slotted. I see mostly street and fun canyon runs with about 6 DE's a year. They are cheap and seem to hold up pretty well.

Good to know. I do about 4-6 DEs a year, thinking I might give them a shot. What pads are you running?
