Gents, I need to replace my rotors and pads for my first upcoming DE event. So I'm a complete newb when it comes to this. Tried a search but the function isn't working well presently.

What rotors would you recommmend for replacement on my 964. Here are a few I've come across:
1) Porsche OEM
2) Pelican has stock non drilled Zimmerman replacements
3) Slotted (what vendor?)
4) Cross drilled. From what I've read they have cracking issues.

I really appreciate your help and recommendations. I'm all ears.

Dan,

Over the years when I was running my 993 everyone recommended and I had great luck with the Porsche stock rotors. They were cross drilled and do crack, but don't wear out that quickly. Some cracking is OK, but you have to watch them.

I'm new to the 964 platform and have carried over my approach and am using Porsche stock rotors and have been pretty happy with them, but still sorting things out a little. I'll be interested to see what others recommended too, but think that Porsche rotors are a solid solution over aftermarket OEM. I have some friends that run an aftermarket cross drilled in the rear, but stock up front. I don't know if this is better or not.

Porsche oem, good track oriented pads w/ thermal barriers, functional cooling scoops, fresh Motul RBF600(Castrol SRF is a little better but 3x as costly)

Skip and Bill really appreciate your input. Oem rotors do seem like the way to go.

Bill, if you don't mind what are thermal barriers?

Dan

Bill Verburg

Modern track oriented pads, like Pagid RS14 and up, incorporate thermal barriers(usually some form of ceramic) as part of the pads design. The whole point is to keep heat away from the pistons and hence fluid.

pantera43

Ok, I understand. Don't they also make stainless backing shields that will do the same thing? If so any idea where I could purchase some.I'll go with the Motul 600. I was thinking of using Porterfields R4s. I'll have to check with Porterfield to see if they use thermal barriers.

Another bump for Pagid. I use the RS14 (black) compound.

As for rotors - I've used Zimmerman and OEM and can't tell the difference. I go with Zimmerman since they are about $100 cheaper per axle.

Pantera - If you are going to be doing lots of track days, a solid or slotted rotor may be a good choice. They will take a fair bit longer to crack. Also, if you are going to do lots of DE's, you may consider getting a seperate set of track pads. It's tough to find a pad that is good on the track and is quiet / low dust on the street. The 964 is nice because you can change pads on all four corners in about 20 minutes.

Good luck!

Appreciate the help guys.

NoSubEDU $200 hundred dollars is quite a savings between rotors. I was concerned with the quality aspect. I'm surprised you found no differences.

Porsche917K my car is seeing double duty as a street/DE car. I suppose I'm not going to have my cake and eat it. As you suggested I might be better off just getting two sets of brake pads one for street and other for the track. From my research the Porterfields sounded like a good pad for double duty.

For track days I found the Porterfield R4s pads to be lacking compared to Pagid yellow or PFC 01s. For rotors I have had the same luck(time to crack/wear out) with factory and Zimmerman cross drilled. going to try slotted this year.

great info...thanks...does Performance Friction PF97 pads have thermal barriers?

I like the PF97's because there is no break in for these pads and they seem to work better for DE's because I change out the race pads to stock pads for street driving.

Hopefully not thread jacking...
To you guys that are changing between street and track pads, are you using them on the same rotors?
Have you had any uneven pad deposition issues?

Edward

I used to track my 993 and did just that: swap from OE Textar pads (Porsche box) to PFC97 track pads ...on OE rotors, daily driver. No issues with deposits, noise, or whatever, whatsoever, and that over maybe 3-4 years of tracking that car. Hope that helps you.

Anybody else using aftermarket rotors vs OEM rotors with good results? If so what vendor? I just want to be sure I purchase a good quality set of rotors.

Never any issues with swapping street pads for Hawk HT-10s in my cars.
